He usally finish 3 - 4 laps down on the top 3 everytime.

We have stopped inviting him to race, practice he can first (Joda talk )

i am having problems with the M05

for the last few weeks it has been chewing gearboxes , 1st i thought it was just the 3Racing gears being too soft/hard but then a tried 2 sets of tamiya ones for our 6 hours race and they are now dust

there is no sign of wear in the chassis the bearings are new , the pinion is a new tamiya one and the shafts are not bent

i can see no reason for the damage , i have tried various oils/greases inside the gearbox but nothing seams to help

any ideas guys ???

Have you tried not using any grease at all? I know some plastics are considered self lubricating as they heat up and additional lubrication will just break them down.

Hi Phil, have you tried the M03 gears (dirty white color) instead of the M05 (very white gears)? Though I've not had any problems with either.

If you lock the diff so its like a spool it will cause a lot of stress on the drive train. Clipping corners and hitting things will make it worse since there's no "diff action" to give so something will break.

Yeah, tell me about it.... Will post of a race with the rest of us later.
Then you can see we are not so bad racers...

I posted new best time with m-chassi at our last meeting. The record was 10.050 sec. My new time was 10.020...
.030 sec improvment, it's close at the top. Normal race you get best lap of 10.100 sec and average 10.600 sec on 20 laps.
We run laps and not time races. And no cutting corners.

Have encountered this problem before. Drilled some holes into the chassis to at the gear housing side to cool the gears down and no such problem since.
don't mind giving it a try guys. If regulation at your state allows.
Make it work like a scoop vents on the under side works the best.

Our phil is running 3racing ball-diff. So it shoudn't cause any problem.

Btw Phil, how long/many minute do you run each time? If anything more than 10 minute, think you should need a stop watch while driving. Anything more than 10min of run, the heat in our enclose gear box won't be able to take the heat.
