Hi all, i need some help. I have a Kraton V2 and a Typhon V2 on 6S. Both are the best RC's i have owned. Fast, very tough and easy to maintain. The only thing that is really starting to anoy me are the rear hub inner bearings. After 2 to 3 packs i have to replace them otherwise they get stuck and destroy the hub. The front ones last for over 20 packs. I know the rear ones are more stressed but it's no fun anymore. I have found multipule threads in different forums about this problem. So i started to investigate what the problem is. I first made an outer protection but it made no difference: When i was cleaning the hubs yesterdey i noticed the inside of the hub and bearings is full of sand. So i started to investigate why and figured the problem is in the wheel axle. The slots in which the dogbone moves are too long and stretch beyond the bearing. Thats where all the sand comes in: The sand gets behind the bearing and is pushed in. The front CVD's do not have this design, they are closed, so i think that's (also) why the front ones last much langer. Now i am trying to find a solution. I have tried to close the slots with heatshrink tube: It doesn't really feel like a solid solution. I thought of placing CVD's in the back, but that's an expensive solution if possible. Maybe some kit or shoegoo but i doubt that's going to last. There is very little space between the bearing and the hub so the options are limited. Does anybody have an idea how to fix this for all Arrma enthousiast facing the bearing problems? Thanks!!
