body for Ultimate Rockbull II Crawler...

[WRXronald]

your comments: Ultimate Rockbull II Crawler RTR..

ok hi all....

after searching the 'for sale' lists... i deciced to just go all out on the first shot here (wasted so much money on a stock t-maxx upgrading it, then a micro T-Rex heli and upgrading that)--- now i'm just trying to get into Crawlers HEAD FIRST DIVE with something cool.

I discovered Rc rock crawling.com and they seem to have the most 'tricked' out kits and so i skipped some of the hassle of build up and bought the RTR Ultimate RockbullII Crawler.

what do you think of this rig? Will i be able to get some serious practise and learning done in the crawling hobby with this rig?

this is a link to the RTR setup--- What body can i get look 'right' on this setup? i want it to look 'monster truck'.

here is a link to another truck on the site--- this is the type of body i want to get. Does anyone know where i can get a body this size and looks like that?

scroll to the bottom and see pics of F-150 body painted with flames. very cool body and looking for vendor selling something like this.

thanks for any links or advice.

i also purchased a couple battery packs from tower:

Associated Hyper Pack 3600mah ----- http://www2.towerhobbies.com/cgi-bin/WTI0001P?&I=LXLPW0

will these batteries work ok? can i use an old MRC 15minute quick charger that i have from yrs ago... (probably at least 15yrs old). (used to use it on regular 7.2v batteries for my electric buggy 6yrs ago). if these batts are ok, what kinda run-times should i expect?


also--- anyone know the plain 'driveability' of these setups, other than crawling. i realize the diffs are locked for traction, so jumping and whatnot is certainly out. but can i still tool around the backyard and 'bash' a little with this. or should it be purely reserved for ROCK only climbing/crawling?

thanks for a little patience, i'm a nOOb to crawlers, but not to R/C models :lol:

No, first, MRC chargers suck and second, that charger probably wasn't made for Nimh batteries. I suggest this charger. Its not the best, but it works. I've had mine for over a year now without any problems.

those crawlers are rip offs u could build a real nice txt for that much u do not want to buy one of those

 

[WRXronald]

well...

its late for that now.. cuz i already ordered one. from what i could see those kits have some pretty good articulation and whatnot. i'm just looking to do some 'backyard' crawling and whatnot, nothing REAL serious-- just another toy for me really. consider it like this, i was going to just get a mini PTI Goliath for crawling and bashing, and i don't even think you could compare the 2 on any level, but i realize that what you're saying 'for the money' it may not be worth it to most. but if i have the money to throw around and not the time to model it, then it was the way to go for me.

guess i'll just be using my 7.4v lipos instead in the setup. those should suffice, no? 2220 Tanic Taps and Thunder Power 2100mah lipos--- have several of each.


might even be able to parellel two 2100's for a LONG run time that would be cool. fitment in question of course.

what about larger/longer body's. probably looking for something over 20inch, but i can't find one anywhere.

 

[EeePee]

I wouldn't take advice from people who don't bother to capitalize, punctuate, or spell worth a damn. And if he wanted to build a TXT for that much how is it any different than this truck? Maybe he wanted a Clod and not a TXT. DUH!! :roll:

WRXronald, check out this site http://www.tri-statecrawlers.com it's where the Ohio and neighboring states chit chat.

Since the differentials are locked they don't turn very well, but that's what 4 wheel steering is for. Crawlers tend to be pretty slow, so backyard bashing isn't really all that great.

 

[spookyseven]

wow, for $1500 you could probably have a nice serious big crawler, like a txt, clod or maxx, and a tlt with a lot of money left over. you better turn around and assume the position cuz you just got pooned.

oh, and the body with the flames is a juggernaut body, if you dont even know that, you shouldnt be spending money yet

sorry if i am harsh, i just hate it when people get ripped off

ProLine has lots of body choices. Any of the lids designed for the Maxx trucks should fit.......

bum...

i thought the TXT was 1/8th scale? that's what this truck is. seems big enough to me. hosed or not, i have what i have. now i think i'll just focus on having some fun with it, and that's my whole idea about it. personally, of all the rigs i've looked at so far in the last 9 days trying to familiarize myself with the 'hobby' of crawling-- its the coolest looking one i've seen so far. ESPECIALLY with the paint job on that :roll: juggnaut:roll: body (sorry i did not know what body that was. yes its too early for me to be spending money on this, but what's new. i tend to do that. I bought what "looked" to be the most decked crawler i could find as RTR as i could possibly find. that's pretty much opposite most you guys like to do, model the HECK out of them is all.

BTW i found out the body is for sale, i'm buying that too. should be pretty cool looking custom airbrush with skull on the hood (according to the vendor). i'm getting ho$ed on that too and won't even say what paying for it. alot but its a BADASS paint job.

But i do model, SO much as a matter of fact that i needed a break. TRY maintaining Trex 450x Helicopter and not to mention flying it. (can take a bunch of your TIME). so anyways i just looking for a break from that in the winter and nice easy RTR truck for some fun, i 'stumbled onto' crawling and thought it looked quite neat.

hope i get at least 'some' of what i paid for.

 

[EeePee]

I don't think these people realize what it is that you bought.

Full metal light weight rockbull chassis
Full metal straight axles (front & rear)
Adjustable piggy shocks
Aluminum 4 wheel steering kit & servo mounts
16.5" inch / 440mm wheel base
Two high torque motors & full ball bearings
Aluminum spool gears (locker) front & rear
Chrome platic wheels and moab tires
Weight: 10 lbs / 5 kg (approx.)

well the link is there... just in case there was any confusion. EP you saying this is indeed a good kit and capable climber/crawler?

 

[quick5pnt0]

First things first. This isn't meant as a flame so please dont take it that way, but what is with people who ask about a product AFTER ordering it. No sense asking whether it is worth purchasing anymore if you already took the dive.

Secondly i think you'll do just fine with that kit. $1500 sounds like a big chunk of change, but most people dont realize how much they've actually spent in the long run when building their rigs. It doesnt matter if you spend that amount $100 at a time or all at once, in the end it comes out the same.

Good luck and when you get it all setup and running post some action shots!

 

[EeePee]

Yeah man, it's based on Clod Buster axles, which are very popular, and very capable. Then everything is metal, which is cool as ****.

 

[WRXronald]

yes no flame taken, (i expect to get flamed anyways) since this i am exactly the type of person that everyone would be flaming on the helicopter forum for asking questions about a specific corner of the hobby like rock crawling, whilst knowing VERY little about the hobby as of yet). but i learned R/C helis INSIDE and OUT, UP and DOWN, in less than 12months. confident i'll learn rock crawling as well.

Exactly as you said, either $100 at a time or $1500 up front--- i spent ALOT MORE on r/c helis in 12 months (bout 4.5times that if you really want to count $$$) and i have LESS to show for it then this truck. (one FULLY decked out Trex450 micro-heli and ALL the supporting lipo/brushless/tooling to go with it-- NOT CHEAP).

so for almost 1/5th the cost i get a COMPLETE truck setup that is ready to crawl like a champ (from what i could see anyways).

so thanks for the comment. i have LITTLE doubts that much FUN will be had with this rig.

as for asking if its worth purchasing? honestly--- i wasn't really asking that. i took it upon myself to assess whether i thought the kit was worth purchasing and decided yes it was. now i just want to know if some peops "in the know" feel the truck will perform, not if it was worth the money. I'd be elated to hear that it will perform as well as a decked out TXT or Clod (i think it will easily match those), but even if folks don't think it will perform as well, i'm STILL going to have lots of fun with it. (i came VERY close to bidding on ebay for a stock rtr TXT used in good condition with battery and charger, etc-- buy it now was $475 shipped). i can say this rig for 3 times the cost DEFINATELY looks to me 3 times cooler than that TXT!!!

EP thanks the linky, i'll swing over to that site shortly. hopefully gets some picks up once i get crawling.

anybody ever use a brushless motor to power these rigs? guessing probably not because of motor-cog on a some of the brushless setups? maybe not smooth enough on engagement. (and since brushless setups run ideally at 100% throttle engagement that is not ideal for a crawler that is trying to be geared low. although brushless motors DO produce INSANE torque comparatively. why not use them with something like a high quality Kontronik JAZZ ESC, should be able to produce smooth enough slow engagement?)

sorry for the lonnnggg post.

heck look at the shocks on the thing-- they are quite awesome i think--- huge resevoir piggyback w/HEAT SINKS on the piggy portion, to keep the oil a consistent temp inside the shock??? i mean hello? i don't see that on too many Clods or TXT's around the forums? i thought that was a SICK option (in a good way of course ;-))

I'll stick to my plastic shock that wiegh a 1/8th of those. You won't EVER need a shock like that on a crawler. We don't cycle the suspension fast enough to heat up the oil.
Yes it will perform well. But it is really heavy wich will hurt you on most climbs. It will get hung up on the center chassis. It will also shorten the life span of the motors.
It's a good crawler if you like the look.
You will have a lot of fun with it any crawler is fun. ;-)
IMO it has too may parts that you don't need. The lockers jb weld works great. The aluminum gears. I've never had a problem etc....

[WRXronald]

yeah...

good points.

i guess i'm just a sucker for BLING parts. always been one of my fatal flaws. :mrgreen:

again--- could brushless be used in these trucks? to get longer motor life and increase effeciency? how long or many drives should these 55T lathe motors last?

are the brushes replaceable i assume? thus the motors just need to be maintained over time and they can be used.

although no matter really---- from what i saw the 55T Lathe motors are DIRT cheap!

heck i'm used to the brushless motors cost-- i've spent over $150 for just one Lehner brushless motor (hand made in Germany) for my micro rc helicopter!!!

$25 for a 55t lathe motor is an not bad at all on the cost-front.

at $50 for 2 motors, if i am replacing them monthly or something i would CERTAINLY try to make the brushless setup work out--- lifetime of a brushed motor would be insane comparatively.

but if its something where i am going thru one pair of motors per year, then i would likely be content to stick with the brushed lathe motors.

of course--- Brushless = BRUTE POWER!!! muhahahahahah!

i put a brushless Warp4 motor in my MiniQuake SE with a 11.1v 3cell lipo--- top speed 40mph!!! YEASH its fast.

the crawler not supposed to be fast--- but it could be SHEER powerful with brushless!!! :lol: ha i trying to mod this thing already and i don't even have it YET... :roll: can just see it now--- twin lehners (2039kv) with twin Kontronik JAZZ esc's and twin 2100mah Thunder Power 7.4volt lipos!!! this could get outta control fast. just what i need, another money pit! :roll:

or why not use 2 of these? Novak SuperSport plus brushless http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXKUX5&P=ML

does novak make a brushless capable esc that can power 2 motors at once?

probably tear up the drivetrain if not careful, eh?

here's a link to the motor: http://www2.towerhobbies.com/cgi-bin/WTI0001P?&I=LXFPW1&P=V

high torque, good driveability per the notes, 540sized should be ok fit, and ultra effecient. if theres room to squeeze 2 escs, 2 batts on the chassis somehow... this SHOULD make a stupid powerful and effecient crawler, no? or maybe now i'm just talkin' out my arse... :mrgreen:

That's funny right there ^^^^^

The rockbull pictured in the links WRXronald posted was built by me. If anyone thinks that it is not a comp worthy rig, you are wrong.

Ask anyone who has seen it perform what they think. I've been able to go places with it that other rigs can't. Or at least not as easily.

It may not be able to hold it own against a stick (not sure, never wheeled with one) But I would gladly put it up against anything else out there. ;-)

WRXronald, Don't let these guys who have no clue what they are talking about get you down. :lol:

 

[JohnRobHolmes]

you have checked out the brushless thread, read up on what we have learned. Outrunners would do just fine in a clod, but not inrunners. Brushless is totally workable, and the outrunners spin slow enough that near full throttle running is possible all the time.


your rockbull will do just fine. Your bling wont last long, and you will probably need new shocks if it falls hard a few times on the aluminum piggys. Still, it is a nice rig.

Bwahahah!

You mean like this?

Looks like he bought this one, and it looks pretty darn cool! Post some pics when you get it out on the rough stuff.

Awesome ride!
