Stripping screws
You have some problem to remove genuine screws on your caliber 30. They seems to be made of a very soft/cheap metal.
Cause?
Head screws used are Japanese Industrial Standard (JIS). Regular metric screwdrivers will not work.
Possible solutions:
- Buy a set of JIS drivers from Heliproz/Cyberheli/www.custom-rc
- Buy stainless allen head replacements.
- Buy an upgrade kit at www.custom-rc
