Rgt rr-4 Found this guy on ebay for $210, at a glance it seems to be similar to the redcat Everest 10. I bought one, will post my thoughts/overview when it shows. "thumbsup" Published specs: length:480mm Width:280mm Height:210mm Wheelbase:350mm Ground clearance:84mm Weight:2800grm wheel diameter:54mm(2.2inch) Tire diameter:140mm Radio System:2.4ghz Esc:Waterproof 45A 2in1 esc Servo:Waterproof 9KG Battery:7.2V 2000mah nimh Motor:Brushed rc540 Gear ratio:1:48 http://i498.photobucket.com/albums/r...man271/6_1.jpg http://i498.photobucket.com/albums/r...man271/5_1.jpg http://i498.photobucket.com/albums/r...man271/4_1.jpg http://i498.photobucket.com/albums/r...man271/3_1.jpg http://i498.photobucket.com/albums/r.../s-l1600_1.jpg http://i498.photobucket.com/albums/r...ttman271/8.jpg http://i498.photobucket.com/albums/r...man271/s-1.jpg |
Re: Rgt rr-4 Without further ado... Some interesting features not mentioned in the ad: The body is hinged at the front and the whole thing can be removed with two screws. It also has two working headlights. Here is the truck without the body bolted on: http://i498.photobucket.com/albums/r...1/DSC_0258.jpg http://i498.photobucket.com/albums/r...1/DSC_0259.jpg Links: 6mm O.D. Links w/ 3mm threads U joints: are metal of some description with plastic driveshaft tubes Wheel wideners are an extra 15mm on each side. http://i498.photobucket.com/albums/r...1/DSC_0260.jpg Esc is an actual 1040wp, ran it on 3s and it didn't blow up. It also comes with fake deans, not the tamiya plug. http://i498.photobucket.com/albums/r...1/DSC_0263.jpg http://i498.photobucket.com/albums/r...1/DSC_0264.jpg Much to my surprise the tires are super nice, feel like a good compound and the foams are also well suited for the weight of the truck. The rims are an axial copy of the face but as a glue on, they also seem to be well built. http://i498.photobucket.com/albums/r...1/DSC_0265.jpg Side note: Don't boil or bake the rims to get the tires off it just warps the hell out of the rim. Here they are vs the proline http://i498.photobucket.com/albums/r...1/DSC_0261.jpg http://i498.photobucket.com/albums/r...1/DSC_0262.jpg What I like: Truck generally seems well built Not too much slop anywhere Great tires Standard size equipment Shocks aren't leaking What I dislike: Abysmal turning radius Philips hardware Brittle plastics...... Had the truck out for it's first run and snagged a tire on a rock, my fault but I'm convinced those stupid wideners had a hand in this http://i498.photobucket.com/albums/r...1/DSC_0266.jpg http://i498.photobucket.com/albums/r...1/DSC_0267.jpg I'll be damned if I'm dropping $30 to replace the parts on these axles, going to slap something else under it. Ask away if you need any measurements or pictures, I'll do my best to provide"thumbsup" |
Re: Rgt rr-4 Does look very similar to the Everest 10. Not sure if I like the 2 tits on both undersides of the pumpkin/diff housing. Hope it turns out well. Will check back to see the results of the reveiw. |

Didn't know they were like that on the original scx10 axles unless the previous owner of mine grinded them off. Sadly I got rid of it before I could do any real crawling or modding. Did pick up a new 10ii and TH U4 though. *Update* Everest 10 axles you stated.. they have the post's too I see.. |
Re: Rgt rr-4 Come to think of it, I ran those axles on a mutt hilux build too. http://i657.photobucket.com/albums/u...1AC672C329.jpg |
Re: Rgt rr-4 Like with my rgt rock cruiser I bet it's a clone of something ecx and hsp has in the works they haven't released yet. And with the axles are Everest 10 based that good at least axial parts will work to beef them up. |
Re: Rgt rr-4 I think that's a pretty good looking truck. TVP chassis suck though. That price though! I read it as $120 which would have been great. $210 is too much. |
Re: Rgt rr-4 i kinda like it. subscribing for the review. might make a decent beginner crawler for my will be 8yo for christmas. plus being basically an axial rip, parts will be easy enough to sort out. |
Re: Rgt rr-4 Oh btw. Plan on replacing the lockers soon after the first run with some axials. The stock lockers in those axels are plastic or well they used to be anyways |

Truck is scheduled to show up Friday, will give it a rip this weekend |
Re: Rgt rr-4 The everest has 2.2 and plastic lockers. Most likely like the Everest you are going have to file down the axle shafts to fit in the axial locker and if you go axial gear shiming the pinion too |
Re: Rgt rr-4 I found this by accident while looking at battery chargers. It was $187 here, but is OOS now. RGT 1/10 Rock Hammer Crawler RTR (Yellow) |

Re: Rgt rr-4 Updated second post with my initial thoughts |
Re: Rgt rr-4 Kinda a sham about the c-hub and axle shaft. |
Re: Rgt rr-4 Most people replace those knuckles a nd c hubs with axial ones. Also the locker/spool in those is normally plastic so you need to cut the plastic post off and drop in an axial locker. Then you can also run axial axle shafts. Alternatively you can buy the hsp locker. 180009 is the part number. But the axial shafts don't work on the hsp/rgt locker as the tang on the hsp is thicker than the axial one. https://uploads.tapatalk-cdn.com/201...541e0e744f.jpg Sent from my SM-G930F using Tapatalk |
Re: Rgt rr-4 Good deal on the review. I still think it's bs to pay that price for it and it needs locker upgrades right out of the box. At least on this it has rear lock outs unlike the Everest 10. If this would come down to Everest 10 pricing I'd consider picking a couple up for my daughters. |
Re: Rgt rr-4 G’Day all, I spotted one of these on eBay and picked it up in the hopes it would perform the role of a cheaper Rock Racer + kids bushwalking car + loan car for friends. I’ve got a Redcat Everest 10 (E10) that currently performs this role but I’d been finding it a bit too slow and not well suited to aggressive driving. So here’s my 2c in additional to what’s already been mentioned, specifically compared to my E10 which I know is not a like-for-like comparison but hey, its what I was comparing it to and as mentioned earlier they share lot of drivetrain parts. Likes * Tough plastic tube frame body structure with front bumper bar – I’m not having a panic attack every time the kids pick it up by the roof or when it rolls * Faster than E10 – Whereas the E10 has a 40T brushed motor, this has the same motor as the HSP brushed drifters, rally cars, etc so it should be 27T motor. On a decent output 2S LIPO you could say it has Rock Racer speed (just), on 7.2v NiMH its probably more like a quick crawler * Lots of drivetrain parts shared with E10 (see further details below) * Better tyres compared to E10 - Softer / stickier compound, slightly higher and narrower providing better grip * The front axle is rotated inwards slightly vs E10 (due to lower angle of the drive-shafts as the transmission is lower), which raises the height of the steering links which in turn reduces their exposure to damage * The battery tray has raised sides vs the E10 one, keeping the battery in place much better * The lights are a nice touch * Light and compact transmitter with throttle EPA * Ease of switching around the battery and electronics front to back (the mounting points on the chassis are identical front to back) (which way is best for rock racing??) * The driver figures are a nice touch, especially for the kids * Like the E10, axles are somewhat compatible with Axial parts * The ESC is good for an RTR with easy swapping between NiMH and LIPO * Wiring is less exposed than the E10 * Has a proper chassis-mounted front bumper vs the E10 which has none Dislikes * Axle internals aren’t the same part numbers as E10 and aren’t easily available yet (can anyone recommend any sellers of hard to find HSP parts?), but I guess you could always use E10 parts if needs be * The turning radius / steering angle isn’t great (similar to E10). For trail runs it isn’t doesn’t present much of a problem but for precise crawling its pretty average * Would have been nice to have some more drag brake options as 100% can be pretty harsh * Cheap feeling transmitter What key parts are identical / different vs the E10 * Faster brushed motor on the RR-4 as mentioned above * Axle shells are the same but not the internals * Link mounts on the axles and servo mount are identical * Steering knuckles and C hubs are identical * If you upgrade to an alloy locked diff the part is identical, but the stock parts are different. Maybe they put a stronger locked diff in the RR-4 after all the reports of the E10 plastic ones failing * Transmission (including spur and pinion) are identical (so same gearing) * Transmission mounting plates are identical * Centre drive shafts look similar but are different part numbers. Perhaps the RR-4 has longer driveshafts but I couldn’t tell any difference * Shocks on the E10 are much longer * Each uses different links (including different steering links) but note all the RR-4’s ones are straight, there’s no bent ones like the E10 * The rear axles use lock-outs / rear axle covers (what’s the right name?) (similar to a SCX10) vs the E10 setup. The E10 looks like it has half the pieces ready for rear steering to be added – Can anyone help me understand the significance / benefit of each approach??? Key dimension comparisons vs the E10 * Axle height off the ground is almost the same. The RR-4 has slightly taller tyres but it would only be a mm or two gain. Note my previous comment that the steering links are slightly less exposed on the RR-4 * The height of the transmission base plate off the ground is 81mm on the RR-4 and 98mm on the E10 * The RR-4 has a slightly longer wheelbase 335mm vs the E10 at 320mm * With the wheel wideners (correct name??) the track width is wider on the RR-4 at 220mm vs the E10 at 205mm * The RR-4 can get a front wheel 100m off the ground before a rear wheel starts rising (measured from the lowest point of the front wheel) while the E10 can get to 115mm before this happens Thoughts on the radio system (HTX-2) My initially thoughts on the radio system were not great. Compared to the standard Redcat / HSP remotes (the Flysky GT2 knock-offs) (which although quite basic, I’ve yet to have a problem with one) the transmitter felt really flimsy and there is next to no travel on the throttle (works like an on/off switch) or steering. Having said that it‘s very light (4x AA’s) (good for the kids) and compact (I can drive with one hand while jogging). It has the standard servo reversing and trims, dual rate steering and surprisingly throttle EPA which can help slow the truck down to crawling pace or for kids to use which was an unexpected / uncommon bonus. I thought for a minute that it might be a full 3 channel setup as there is space in the receiver and a switch on the transmitter, but so far testing the lights I can’t get it to work. Note also that the on/off and 3rd channel switch covers are small (like choking hazard small) and will pop off easily. Misc notes * Design wise the RR-4 keeps it’s weight lower and spreads it further front to back vs the E10, more suited to a Rock Racer I guess * Those posts under the axle pumpkin on the E10 (used to mount a bumper on the HSP Pangolin variants) seen in some of the marketing shots weren’t there on my one * When I initially went to pull the body off to access the battery etc, it felt like I was going to break something. With the levered body you’ve really got to give it a solid tug at the back to get it to pop over the rear body posts * The WP1040 esc on/off switch can be mounted upside down and accessed easily through the bottom without taking the body off * Mine came with Deans plugs although the advertising pictures were of Tamiya plugs * The levered body is a nice touch and strengthens the front bumper somewhat, but sometimes it can make it difficult to work on the car Drive Impressions I should note here that my experience with Crawlers is limited to a SCX10 Honcho and E10, both largely stock (the original E10 plastic diff lockers are holding so far!). More relevant is the fact I have no experience with Rock Racers. What I was after was something with a little speed that I could take on trail runs; Something that I could bash and leave my SCX10 to be kept in decent condition; Something that wasn’t going to cost a lot; And something kids / friends could drive on bushwalks without me cringing every time they crashed. Again I was comparing to the E10 which isn’t a fair comparison I know. It’s early days but so far this truck delivers on all of the above, so much so that I’ll probably offload my E10 and get another one of these. In terms of crawling ability they’re almost on par in stock form. The better tyres of the RR-4 give it a bit of a grip advantage and the lower CoG can help with side hilling, while the higher transmission mounting plate and longer shock travel of the E10 give it an advantage re break over angle and when the axles get all crossed up. Obviously adding some decent tyres to the E10 would give it the win though. Both suffer in this area with poor steering angle / turning circle and a weak servo. In terms of Rock Racing, in stock form the E10 isn’t really in the picture. A faster motor could be easily added but the crawler design I’d suggest doesn’t lend itself rock racing. The E10 also gets a decent amount of torque twist which the RR-4 doesn’t seem too. Final thoughts In stock form the E10 is only a Crawler whereas the RR-4 can be a Crawler or Rock Racer. So for what I want it to do, the RR-4 gets the win for me. As a cheap Rock Racer, a trail truck for the kids or for those wanting something faster than an E10 it certainly seems to fit the bill… Cheers, Crouch |
Re: Rgt rr-4 Is there a source for replacement parts? I really want the cage/body! |
Re: Rgt rr-4 Quick update, I ended up getting a second one of these which came with Tamiya plugs and a different radio with similar electronics and functionality to the normal redcat flysky GT2 ones but with a different shape and only 4x AA's. Cheers, Crouch |
Re: Rgt rr-4 Guys I'm about to buy one of these for my 8yo birthday in august, being based on axial I figure they're pretty tough? are the elecs actually waterproof at all? |
Re: Rgt rr-4 Quote:
Can't comment on the toughness yet as I haven't driven it enough but i'm hopeful! Some of the electronics are advertised as waterproof but personally i'd take it with a grain of salt. They may well be but i'd suspect other parts of the car may rust... I'd treat them as splash proof personally but not much more. Cheers |
Re: Rgt rr-4 Cool, that's fair enough too. As things break I'm sure I can fabracobble on my axial spares n such. Keen to see his reaction. It's the 20th this month. |
Re: Rgt rr-4 3 Attachment(s) Here is how the original truck has progressed. Not much left other than the trans, skid, and chassis plates. 😁 |
Re: Rgt rr-4 Hey, Quick update on the two i'm running with a couple of things to look out for. I handed them over to my kids and their cousins (aged between 5 and 10) (just on 7.2v NiMH) and let them run amok in an empty dam. Pretty quickly the steering went on both. The stock set-up has no servo saver and both of the plastic servo horns stripped, plus both servo's now have problems centering now. Additionally the servo has a metal head on it and normal screw thread (not tapped) and both screws holding the servo's horns backed themselves out. A little disappointing given they're supposed to be rock racers but I guess not surprising considering the price point. So I strongly recommend adding a servo saver immediately to avoid this problem and extend the servo life, plus thread-locking the servo screws in place. Secondly the plastic rear locker/spool in one gave way (as expected) but thankfully I had one of the HSP Everest 10 metal ones to swap in. Recommend ordering one or two of these to keep on hand. Apart from those two minor / expected problems i'm pretty happy with them as crawler / rock racers for the kids to use. Cheers, Crouch |
Have one and love it!!! Bought on eBay for $115 used. Had to upgrade Servo, one came on it stock actually melted threw in a tactic and it’s been great. Thing climbs unbelievably well. Did strip out locker but upgrade aluminum parts for these rigs are plentiful on eBay, for 10.00, hoping it’s ok quality. Have ordered aluminum c hubs and steering gear to help poor turning radius. Wish I could figure out how to post vids on here cause took some great ones today with only three wheels crawling like a champ. Great for trailing as well, little more speed be ok so batteries next 3s ready so that’s big bonus. But for less than $200 gonna have awsome tough rig. When u pick it up just feels rugged. Softer shocks be nice though. OP right about tires as well nice grip for stock! BTW also goes by FTX Mauler Crawler, British, but has all parts for sale online . FTX has cheaper 2in1 esc/reciever. Also Exceed Maxstone 10 also shares many parts like E10. Honestly it’s kinda like a Wroncho. Has wide stance like wraith but more of an scx10 chassis etc. honestly the chassis and frame is unbelievably nice better than axial imop!! Little video of it crawling on rocks for anyone that wants to see it basically stock diff body I had, and new Servo, along with it bein 3 wheel drive in vid cause of shitty diffs. New ones haven’t arrived YouTube Rgt rock racer crawling pt2 http://youtube.com/watch?v=GZR2dGa3ROE Video of rgt rock hammer flexing over rocks with one rear wheel slipping. For anyone looking to help steering radius, go on eBay buy hsp crawler Steering c hubs and steering arms come in sets of 2 aluminum upgrades. Trading those out for less than 15$ will seriously help out the steering radius, the stock ones that come on all redcat, exceed, hsp, and others are bulky and hit impeeding on turning and burning out servos also I believe. Upgrade also looks good |

an ally locker won't hold up to xrmod steering. i shredded a gpm ally locker in my ar60 with universals. |
Re: Rgt rr-4 Its the same axle as Everest 10 / gen7 axles it will fit lots of Everest 10/ gen7 guys use them. I even have underdrive gear and locker in my Everest rear axle. |
Re: Rgt rr-4 Aren’t the axles wider on the rr4? It’s axles are same width as wraith, where the gen7/e10 more like scx axles. I realize this has nothing g to do with steering upgrades, just observation. The aluminum ones I put on almost let front tires rub bumper. And when I put stock body on today, been running different body, there was tons of rubbing. They still stick Dow where as high steering ones don’t. Could one of u post link to highsteers u put on? |
Re: Rgt rr-4 Quote:
The axles are the same, the hexes are wider. Its cheaper to make new hexes and stub shafts then build a brand new axle design. All hsp based rigs use the same axles. 1/10 rigs and 1/12-1/18 rigs there are only two axle designed 1/10 is base off ax10/scx10. 1/12-1/18 are based Off of losi mrc/ vaterra slickrock.

Re: Rgt rr-4 THANK YOU hillbillyrc!!! "thumbsup" Thanks to Photophucket's now infamous Debacle, your post was the first look I've had at this interesting Rig. I'd say it's a decent bargain Rig..... They just Forgot the bargain bit! I'd try one, as I NEED lower priced Stuff. But over $200?? NO freaking way! Thanks for all the insight in this Thread. If I can find one used...... ;-) |
Re: Rgt rr-4 I've seen them prices below 200 and free shipping |
Re: Rgt rr-4 Seems too me that $200 is fair market value for this rig. Haven’t run a gen 7 myself, but this is definately comparable. I’d actually be surprised if gen7 can keep up with rock hammer under almost any test stock. Climbing mudding or racing. Gen 7 has scaler body, but that only bonus, throw a proline on this and it will look bad ass!! Only going at gen 7 cause same price range, and seems to be standard bearer for that price range. |
Re: Rgt rr-4 The HSP version sells for about $220 AUD down here. Approx $170 USD. Sent from my SM-G930F using Tapatalk |

Re: Rgt rr-4 The gen7 tires do look nice, watched bunch of videos on em after my previous post. The rr4 tires are very sticky, but tread not as aggressive looking? The rr4 tire is a 2.2 they’re big, and heavy. Been driving in snow and cold mostly and they get hard, still work good cold, but they’re very soft at room temp. The gen7 looks like a great car as well, as far as the electronics transmission axles etc they’re same rig, with different chassis and bells and whistles. After watching a ton of videos on them don’t think I’d choose it over the Rgt, for rock crawling the rgt is awsome, which is what I like doing mostly, with wideners however cheap and long wheelbase it’s super stable. Little video nothing special driving one handed for first time� http://www.youtube.com/watch?v=VkolVgk5PyQ |
Re: Rgt rr-4 G'Day, Just a quick note that Tower Hobbies is bringing these into stock under the name of 'Force Hammerjaw Rock Bouncer', looking largely the same as other offerings (FTX Mauler) with different body graphics and electronics. I notice in the pics that some of these more recent models have a guard over the spur gear which I think is a nice addition, as i've had a battery cable get chewed up as it passed straight over this area. My two are still going quite well despite my kids giving them a beating! Cheers, Crouch |
