Hobbyzone Super Cub Lives!

After many months of trial and error, and replacing every part except the motor and gearbox, the Super Cup flies! My lack of experience accounts for the necessity to replace almost every part, but I learned a lot in the process. In the end it turns out the wing was to blame. Though it looked true I now know the dihedral was off (as a result of crashing several times) which cause the plane to pull hard to the right.

I am in the process of doing a custom paint job so I'll hold off on any pictures until that happens. As I mentioned all the parts have been replaced with stock parts with the exception of the electronics and wheels. I currently have a HiTec Mini 6S 72Mhz receiver and a Great Planes Electrifly C-35 ESC. I went with a higher amp ESC that I really need but I want to be able to use it in the Estes Air Force One when I finally get around to modifying it. I decided to take a chance and go cheap..real cheap on the servos, I ordered a Hong Kong special from EBAY for around 5 dollars each including shipping. They are called SG90 and are have similar specs to other 9 gram servos on the market. They are a perfect fit, and other than being noisy, they seem to work fine. I realize there is risk of failure, but the fact that this plane is very cheap, and that I fly at a field that isn't heavily used, makes me worry less about safety concerns. In my quest to find cheap parts I also picked up an Esky brushed 40A ESC on EBAY for 14 dollars (including shipping). Though it is supposed to have a low voltage cut-off, in my tests it ran the battery so low that the receiver started to cutout and send intermittent inputs to the servos. This isn't a risk I am willing to take so I wouldn't reccomend going cheap on this part.

Initial Flying Impressions:

After flying only the Multiplex Easystar for so long this is really a change. I think the Super Cub is a good step up as its flight chararcteristscs are less glider like and more in line with a regular plane. Its also nice to have wheels to make landings and take offs more realistic.

More two follow after the paint job...
