Modifications To gtx800

Here is some pictures of the modifications i made to the gearboxes I have change the gears for motif which is stronger as there is more surface area I have put twin bearings in and shamed the gears are now running with engine oil hopefully they will last much better there is a couple of pictures of the motor If you use the outside screws which hold the motor together take two of them out opposite each other they line At perfect you do you have to mess with the screws to get them to Bolt together
