First flight was made on Sunday 09 August 2009 in Tehachapi. One flight was made, but not without problems. The plane seemed underpowered, and required much more up elevator trim than I thought it would. There also exists about one ounce of lead in the nose, this could probably be reduced. Upon landing the plane ended up on the side of the road with damage to the nose. The plan is to repair and improve it. A thrust tube was not used on the EDF, although the thrust ring was present. I'm doing research on what the optimum thrust tube dimensions should be.
The plane is heavier than I would have liked. I had a 3S1800 lipo for it, but even with the battery pack all the way forward the plane would not balance, so I used my heavier 3S2250 lipo, and still had to add a little noseweight.
Anyway, it was fun to build, and I learned a lot since it was only my third EDF plane.
