I think the problem is as someone pointed out on a different thread that japanese standard (JID) philips screwdrivers have a differently designed tip that does not jump out as opposed to "normal" screwdrivers. If you can get one of those you won't have any problems with the screws. I personally use good quality tungsten carbide tipped screwdrivers with a nice soft handle so I can apply a lot of torque and control the force easily.

ran it yesterday, it is loads of fun. the drivetrain on this is whisper quiet, gotta find some loose dirt and let it rip. might drop-in the 4600kv in there.
the chassis is a vacuum cleaner
