.............or at least someone tell me what they "think" might be wrong.... give me your opinion.... im at a dead end.. and just orderd 2 more stock spur gears from redcat, i shouldnt be eating gears like this!.... i think im "meshing" them right.. using the old piece of paper trick.... would that be my problem?.... to much power using 3slipo? wrong gear meshing?

look at this pic.
its the redcat drift lightening.
i believe it has the cover you are speaking of.
its a 2 piece part right?

i used to run my lightening on 3s. make sure you have the "E" clips that hold the spur in place.
check over the ball bearings that hold the diff pinion.
and did you change the pinion gear?

thats the brushed one... mine is the epx pro... "brushless"doesNOThave a gear cover...but yes to yur questions.i went through the whole damn car thinkin it might bea bearing or somthin.... its the problem of the gears stripping out, because of too much power to them or im not meshing them right.but everone says use the "paper" trick to mesh.. all i know this problem is starting to cost $$$ and ill be damned if im goin to give up on this lil lightning!..... come on people give me some ideas!...lol.....thanx for your responce though!

the part # of that cover is 03401(redcatracing.com)
even tho it comes on the drift, it should work on the epx pro(same chassis and upper plate)

what ESC do you have? when i ran my lightening on 3s, i had the 35amp ezrun speed control. i had the punch control set all the way down(soft)
since the car doesnt have a slipper, a powerful brushless motor on 3s can do some damage if no throttle contol is used.

redcat also has a 64t steel spur gear : http://www.redcatracing.com/RC-Cars/...ts/11188-48T_2

combine the gear cover and the steel spur gear and your car may hold up better.

sorry for some of my replys,
there is another post on the asking a simillar question about lightening spur gears....i got confused between the 2 LOL.

2s lipo will certainly help the stuff last longer.

but so will using a ESC that has punch control.

the gear cover may help if you dont already have it, as dirt/pebbles can get caught in the gears teeth and cause damage.

that stock 70a ESC is the HSP novatech one right? that esc has no settings for punch control or braking ect.

do youself a favor and buy an ezrun 35amp ESC with program card. then set the punch control down, lower the braking force, even add drag brake if you want.

i had the novatech esc on my lightening when i first started running lipo, a set of tires would go bad in 2 runs.(even if i was gentle on the throttle)

then i switched to the 35amp ezrun esc and adjusted the settings. tires lasted much longer after that.

punch control slowly ramps up the power to the motor. this gives a gentler start, saving on the drivetrain and the tires.

the epx pro's now ship with the ezrun 35amp system, instead of the novatech system.

you can get the ezrun 35amp esc on www.hobbypartz.com. its not super expensive, and the settings will go a long way toward saving your drivetrain.

the novatech esc is nice, in that its a simple unit. it self-setup and programing is nice, but doesnt alloy for any adjustments.

i miss my lightening. i sold it awhile back. i did have some issues with the spur as you have, but everyother part held up like it was made of titanium!

i mean, i was not kind to my lightening. i jumped it off ramps, ran it in the dirt with rally tires....always with either 2s or 3s lipos. I bashed the crap out of it.
never broke a hub, a-arm, camber link, shock, steering link ect. for those parts to hold up under the abuse i put it threw was amazing.

the lightening epx pro, RS10 XT and tornado epx pro are my Fav redcat models i have owned. SOO much fun for the low cost.

Stop with the paper trick for setting up......... this may be a bit of trial and error but Istopped usingthe paper between the pinion and spur after I learned that ........ you just want a "tick" of play..(just like in diff shimming)....... and after you think you got itrun a slip of paper thru just to rest easy that you got it right...............
