Re: Choosing a motor and ESC for your Wraith - Gearing Added! Cheers bud, that was my plan. big thumbs up to the support you offer here. are you aware of anywhere in the UK that can support me in my quest for parts? Or even a reliable US site that is prepared to ship to the UK. I'll probably keep the setup while i save up for parts and then place a big order for many items in one go. |

As far as international shipping, I am sure RC Rock Crawlers - TCS Crawlers or www.rpphobby.com will ship overseas. For electronics, holmeshobbies.com will ship overseas, John is very accomodating, send him an email if you need help. Otherwise, I hit TCS first for anything I can buy, then go to RPP. All of them are great guys to work with "thumbsup" |
I think I've decided against the Pro4 as I personally see that much power as overkill, and don't want to have to upgrade all these parts. Instead I think my choice will be the Tekin redline 13.5 or possibly 17.5. I'll mainly be using it for trail running, any crawling will probably be only what's encountered on trails, and maybe a bit in the garden. Would the 17.5 have sufficient speed to take off over small jumps and race uphill or do I need the 13.5? I have MMP and currently 2s Lipo. my Wraith kit is on its way with a brushed motor but may decide to return it and get the Tekin from the start. Sent from my HTC Wildfire |

Re: Choosing a motor and ESC for your Wraith - Gearing Added! Running HH 16t crawlmaster. Just installed RRP steel gears and 54t slipper with a 15t pinion. Running 3s as well. Didn't take the temp gun with me but the whole setup was HOT, motor and transmission. Am I way off with this gear setup? The performance was great, crawled like a beast. Motor was too hot to touch and the tranny case was way hot too. |

try a 11t or 12t pinion, should be much better and will crawl better too. |
Re: Choosing a motor and ESC for your Wraith - Gearing Added! I think the gear mesh was a little tight, causing the friction. My radio crapped out while I was testing it after adjusting the mesh though. Won't this 3.6:1 ratio be better for crawling than a higher 4:1? |
Re: Choosing a motor and ESC for your Wraith - Gearing Added! So i am pretty much completely new to crawling & rc period, & i have done ALOT of reading but I get more confused the more i read & i feel like i know nothing about motors & esc's, i know all motors are different turns for different uses.. so how exactly does it work, i mean is a higher turn better for crawling or is it the opposite? & are there specific esc's for specific turn motors or how does that work? any help is appreciated |
Re: Choosing a motor and ESC for your Wraith - Gearing Added! I posted in the wrong thread so I'll give it a shot here.. I need a little help with my setup. Looking to build a trail runner type of rig; crawler/basher type. I know you cant get everything in one package but just need your suggestions/opinions. I am trying to find a happy median.. So far this is what I have MMP CC BEC tekin Redline 10.5 wratih trans with RR gears/C.I. outputs revo shafts. Plan on running 3/4s I am about to order gears for the axles/spurs and pinion gears for the trans side. This is where I need your help. On the axle side...Should I get: Stock F and R UD F and R OD F and Stock R Or any other suggestions?? I plan on running lockers F/R with 2.2 CAC with tsl (dont know if wheel/tire size affects pinion choice in rc's as it does in 1:1) Also for the trans spur and pinion setup. I want to upgrade to 32p. What ratio would be ideal for my current setup for trail-ability?? I want to be able to run this thing for about an hour on our trail hike without overheating the motor/esc. Any help would be greatly appreciated. Thanks in advance.."thumbsup" |

Re: Choosing a motor and ESC for your Wraith - Gearing Added! Thanks Harley for the info.. Will get those gears together and try it out. |
Re: Choosing a motor and ESC for your Wraith - Gearing Added! so does the 56t/14t gearing for the pro4 apply to all 3 motors? i have the 4000kv one, would you still reccomend this? do you know the gear ratio at 56/14? awesome thread harley, thanks for all the hard work"thumbsup" oh and is all this gearing for 64pitch? right now im 32pitch and 12/64 and it seems like i should gear it down a little, let me know what ya think.. |

Best thing is to apply small amount of loctite and not overtighten them. |

Re: Choosing a motor and ESC for your Wraith - Gearing Added! Quote:
You need to get lots of gearing options and go test the truck to see what setup will keep things at a reasonable temperature and such. Personally I think you'll have a hard time against the Emax. That truck has a drivetrain that is more capable of holding up to the power that you will need to reach those speeds, especially in sand. Even a beefed up Wraith is going to have lots of stresses on the weakest points. Good luck and I hope you do win. |
Re: Choosing a motor and ESC for your Wraith - Gearing Added! Quote:
Im just tired to hear those guys wining on me just because i have a wraith and not a slash or a e-revo or e-max, and i want something to keep their mouth shut, just that. I know it will be hard as hell, but i will try it out anyway. Thanks again harley. |
Re: Choosing a motor and ESC for your Wraith - Gearing Added! Quote:
Thats really the only way to do it. I still think that a Slash or Emax is going to be tough to beat for this type of thing. A solid axle truck is going to be much harder to run at speeds like that. |
Re: Choosing a motor and ESC for your Wraith - Gearing Added! Quote:
robinson spur gear 56 tooth pinion 20t final ratio = 2.8 the one i am using now 80t 48pitch 28tooth pinion final ratio 2.8571... the best that robinson or supershafty is the strenght of the spur gear and the pinion but wouldn i need a lower drive ratio to get more speed? i maybe wrong but with that set up i will beef up the spur gear and pinion but the top end speed would be almost the same or am i wrong? tanks for the reply HARLEY I LOVE YOUR THREADS AND COMMENTS AND I REALLY RELLY ON THEM.
