Actually, i still have spare parts for the tricopter other than this stuff. This is all the extra stuff for smaller multicopters, foamies, etc. My tricopter actually takes 10x4.7 which i am keeping (11x4.7's don't work as well, wobbles on descent, vibrates more, etc.) ...
I should still be able to fly after the surgery (im hoping) but using what little pain free time i will have will not be for scratchbuilding, only flying.
