How many teeth is the spur? Someone might have a 64 pitch gear on it or it is chewed up.

Yes pulling the trigger is forward.

I would do searches for pinion or gear mesh that can help you out. With out more details or even a pic it is hard to tell. If you goto tower hobbies our your hobby store by you can see what a spur gear should look like - just making shots in the dark in what the problems are.

Lots of people on the board here that can also help. Just be patient.

It could be that the motor is hitting the trans and needs a bigger spur gear (if the pitch is correct)

i have an evader st, which is close, but its a good buggy. like they said it might be the pitch. look on towerhobbies.com for the stock part to find the gear pitch. also i was just curious , what controller and esc are you using? if you neede new ones i have a few cheap good sugestions

i looked at tower hobys and they said that the origional spur was an 81 tooth 48 pitch gear, I showed the guy at the hobby shop and he said the spur was ok but could be replaced,He didnt have one ,joy!and im using the stock sprint esc and a dura max rx 100 controler

In case your hobbyshop owner doesn't know, any Associated Electronics or Kimbrough spur gear designed for oval/roadcourse type cars (pancars) will work with the Evader cars so it doesn't have to be a Duratrax "specific" spur gear. As a matter of fact I'd switch to AE or Kimbrough just for the fact they are more readily found.

What do you mean by this?

Are the teeth not reaching far enough into each other or is the mesh or pitch not the same? Or could they be misaligned ?

are you sure your mesh isnt too tight id also change the esc im running a novak xrs, with a 15t fireball, which by the way is a crazy fast setup!, also take one of the heat sinks off your old esc if you get a new one, and ca it to your motor plate, it helps the motor run cooler! also change the servo, the stock sucks!!!!! oh and a good idea would be to change the tires to proline street tires. also if in the near future you find yourself rich get a new controller, youll be better off, hope this helps and good luck!!!!!!!!!

when the motor i set in and i try to tighten the screws the teeth do not come close enough together

rctazmanmc · #11 05-25-2006, 08:41 PM

take the screws out and mount them in the other holes in the motor - there should be 2 sets of holes.

That or your pinions is to small.
