I've tried a few batteries this past weekend with the new rubber sealed bearings. It is just fine. Only one change btw that might or not had influenced in cracking those bearings: This time, I'd closed the top front gearbox cover a little bit on the loose side, to the point of almost having a lost screw. Next time, gonna screw it a bit tighter to see what happens.
I was reading your other topic again, the TB-01 and also checked a picture of that rally track you run, its pretty tight in there isnt it? Do you have any vids of some of your weekend races there? I'm quite curious how both DF03ra and TB-01 handle those tight corners powered by that monster brushless motors of yours. Oh btw, how did you managed to "fix" that DF-03's lousy steering play? One last question today I promise, what is a shrink wrap? I got my steering tangled this weekend by a small rock and remembered your solution, but having never seen such a product before, I can't translate it to any languages that I speak.
Cheers
