This is a little RC copter I picked up recently. It’s great for crashing into walls, windows, floor, blinds, you name I can crash it into it, surely flying a full size copter couldn’t be this hard. Anyway every half dozen crashes or so something breaks, bends, twist, whatever, hence the different colours on the blades etc. This is a co axial type RC copter, it has two rotors on top and one at the back. Co axial copters are prone to toilet bowling when something in the gyro train binds, bends, breaks comes undone; or, basically every time I try to fly it. There is a little blade/gyro stem seen in the second picture, with hinge points jutting out the side, every now and again one or both of these little hinges breaks off or wear down making the copter toilet bowl, fortunately I did have a spare but of course all this crashing into anything that happens to be in the room soon saw the demise of both and I was ready to throw it in the bin and take up something simple, like brain surgery. Instead this afternoon I retired to the workshop and had a shot at fixing it. The gyro stem is quite small, about 22mm long and 3mm in diameter with two hinges on the side. First I had to remove the last remaining hinge then drill through the 3mm shaft with a .8mm drill and then enlarge to 1.4mm, once done I cut a 10mm length off the drill shaft and located it in the hole then reassembled the gyro/blade assembly and then re assemble the copter, dammed if it didn’t work, so I got the spare and did the same to that as well. No idea how long it will last - depends on how many objects in the room I guess. There is a reason why I’m playing with toys: I intend on getting a larger RC drone or copter with camera but rather than crash an expensive copter/drone into everything in sight I thought I learn on this little cheapy first - just as well it seems!
I think this would make an excellent project, using the plastic body parts and copying the working parts in ally, might even withstand my piloting skills!
