Falcon 3D Repair Pictures

My first crash in my new Falcon 3D remote-controlled helicopter was caused by pilot error. I was comfortable hovering indoors, so I took it outside for the first time. The wind was calm and things were going well. Then, a gentle breeze blew. Now, when a wind hits a helicopter, it makes the helicopter more efficient, and adds lift (transient lift?). The wind caused the heli to gain altitutde from about 3 feet (where I was comfortable hovering) to about 30 feet. That freaked me out and nerves got the best of me, and i lost landed too hard, causing a boom strike (where the main rotor hits the tail boom).

That crash didn’t do much damage. It bent the boom, but I bent it back with my hand.  It also broke one of the main rotor grips, which I glued. Glueing that rotor grip was my biggest mistake, because it re-broke later during normal flight, causing a more serious crash. Now, I know better than to try and glue one of those high-stress parts.

Anyways, after a couple of minor crashes the main gear seemed to be a little rough at certain points in the rotation, and the main shaft seemed a little wobbly, so I decided to replace the boom, boom linkage, tail gears (which had a messed up tooth), main gear, main shaft, and of course the broken blade clip. That was a nightmare–it took me several hours. Most of the parts are cemented together, which makes them very difficult to disassemble. In fact, to remove the tail gear from the shaft, I had to cut it away with a dremel. I tried to replace the spindle shaft, but I couldn’t manage to remove the screws, and finally gave up (it seems ok, though, i just wanted to replace it to be sure).

Anyway, I took a lot of pictures before the repair to help me re-assemble it correctly. The instruction manual does have exploded views, but it’s not always clear how things connect. The pictures are huge to show the most detail, and I’ve adjusted most of them to show detail in the dark plastic.

Sorry, i’d put thumbnails, but I guess WordPress can’t deal with images of that size.
