Garry Posted February 8, 2010 Author Share Posted February 8, 2010 Easy answer When meshed 'right', you should be able to rock the spur gear backwards and forwards about 0.75-1mm. To get that, theres two methods (until you can tell by sight/feel): 1. Get a piece of paper and put it between the pinion and spur gear, mesh them, and pull the paper out. It should be marked from the teeth, but shouldn't have made holes. http://www.rc-car.com/index.php/site/article/137/ 2. If you want to use a 22t pinion, fit a 23t pinion and mesh it as tight as it'll go, then take it off and fit the 22t pinion. Either will get the job done though.

carlcurtis83 Posted May 8, 2010 Share Posted May 8, 2010 I have a couple of questions. I have just done a brushless conversion truggy. The center spur is 46t...I don't know what the pitch is. I have found a few pinions with a 5mm bore which is what I need. Can I fit a 32DP/48DP pinion? Does it have to be a MOD-1 pinion? (They are expensive) What would be the best size pinion to get for general bashing? What would be the the best size pinion to get for speed runs? I have found THIS and THIS are either suitable for my needs? Sorry for the q's but I don't want to be spending money on pinions that turn out to be no good.

leongordon234 Posted December 16, 2010 Share Posted December 16, 2010 So thats why when i put a 16 or a 17 tooth pinion with a 88 tooth spur that my hpi blitz has good accelaration but poor speed , it came with a 18 pinion and thats alright so looks like its time to buy some bigger pinions off model sport Quote Link to comment Share on other sites More sharing options...

Mr crew tk Posted March 9, 2011 Share Posted March 9, 2011 Hi there, I saw videos of the mamba monster conversions and I was amazed at what they can do. So I bought one the 2200 v3 combo for my hyper 7 , but I am unable to do wheelies like I've seen in the videos. And the videos was of hyper 7 and truggys. I have a 15 t and a 4 cell 21525c lipo battery, is there any chance you can help me? Do I need to programme it via the USB , if so what's the settings? Please can you help.

Garry Posted July 8, 2011 Author Share Posted July 8, 2011 Sounds like the motor is just undersized for that car, they really need low-KV 550-sized motors. Quote Link to comment Share on other sites More sharing options...
Wrcallar Posted July 18, 2011 Share Posted July 18, 2011 How do I go about knowing how to gear my MERV with an Ezrun 13t and 35a in it? And what mount do I need to purchase? Thanks Quote Link to comment Share on other sites More sharing options...
seanmcgrath48 Posted October 27, 2011 Share Posted October 27, 2011 Hi ,, I've been reading throu this thread, but I must be missing something.... I'm using Ansmann Racing Drift Kenjo Motor - 21T with a 54t / 32pitch Spur , 12t / 32 pitch Pinion.... Do I go Smaller/Larger , Spur or Pinion for more speed..... Don't know my Gear box ratio...

Garry Posted October 28, 2011 Author Share Posted October 28, 2011 More speed = bigger pinion and/or smaller spur gear. 1 Quote Link to comment Share on other sites More sharing options...
seanmcgrath48 Posted October 28, 2011 Share Posted October 28, 2011 More speed = bigger pinion and/or smaller spur gear. Thanks Garry for the reply... Don't think I can get a smaller spur gear ,that would fit... Bigger Pinion yes... 14t or bigger ? Sean... . Quote Link to comment Share on other sites More sharing options...
Garry Posted October 29, 2011 Author Share Posted October 29, 2011 Yep, don't go up by more than 2 or 3 teeth at a time to make sure you're not going too far on the gearing and damaging the motor by overloading it though. Jumping 5 teeth in one go may be too much to ask 1 Quote Link to comment Share on other sites More sharing options...

Chris-RcDrift Posted August 27, 2012 Share Posted August 27, 2012 Hey guys, was wondering if someone could help me out, I still cant get my head around this gearing business but i just bought a ezrun 9T brushless combo, the car its going into is my tt01 i mainly use it for drifting but throw some normal tyres on the odd time just to fly about on. So what would be a good gear setting or would the standard set up do? Any help would be much appreciated Quote Link to comment Share on other sites More sharing options...
NuttyProfessor Posted October 11, 2012 Share Posted October 11, 2012 25/55 fella, thats how i run my 9t combo, on road use mainly but you can fit a 28/55 gearing for outright speed Quote Link to comment Share on other sites More sharing options...
bunnie Posted December 1, 2012 Share Posted December 1, 2012 hi all, im fully struggling to work out gearing on my hpi sprint 2 sport. ive just put an ezrun 9t combo into it but unsure what pinion to use. i plan to use both 2s and 3s lipos. any info will be much appreciated!

rcrallyuk Posted February 19, 2013 Share Posted February 19, 2013 Hey guys. I have tried to read this thread and get an understanding of it but i am failing haha. Some help would be great. I ren a TT01 Rally conversion. I dont care for fast cars and rapid touring spec. I just want to be sure that i am running the best i can for my style or driving (rally) Reading this, it looks like i need to be running a high acceleration as i usually run off road on nature tracks and trails. I have a 27t Sport tuned motor baught of the MS website. I think its just the standers spur and pinion i have. Anyone reccomend a good spur/ pinion set up for ralying. Thanks Andy Quote Link to comment Share on other sites More sharing options...
