In my last blog I posted a plane I made from foam plates, using a 40mah lipo and Air Hogs Havoc heli tail motor. It flew, although not very well, and I said I would make a plane that climbed faster, flew slower, and has no wing rock.

That was accomplished with my second plane I built with more care, in this case a biplane with a V-tail. I fixed the problems of the first, with it trimmed to making tighter circles, flying much slower, and no wing rock. The lack of wing rock improved the climb rate.

As a result, though the start was slow, it soon cleared the treetops and was free to go higher and higher unobstructed. Though I started to run after it as it drifted with the wind, I soon stopped because it became evident it wasn't coming back. For at least 4 minutes I watched it climb higher and higher until it just vanished! I bet by the time it landed it had drifted at least a mile with the wind.

I wondered if it was possible to make a tiny free flight plain using the tail motor from an Air Hogs Havoc helicopter. To my surprise, with a 1 cell 40 mah LiPo, they give off enough thrust to power a small model.

In about five minutes I threw together an airframe from masking tape and a single foam plate I bought in a pack of 30 from the $1 Store. I taped the wires together, and in it's short indoor test flight it quickly stabilizes and climbs at a good angle. Of course, being overweight, it flies super quick.

I was going to try it out this morning, but it was raining. Looking forward to a true "fly away," as this motor is perfectly content at running at 1.5 volts, and the LiPo starts off fully charged.
