Hand Launching the Dynam EZ Hawk and Hawk Sky-- TIPS

I tried the FMS FHX-1280 ( I have no idea what those letters stand for, but the 1280 is the wingspan in mm) in a fairly high wind, 15 mph gusts, and found it stable and easy to control. It was easy to gain altitude, power was so problem, and it was easy to launch. The Dynam EZ Hawk, also flown today, requires a lot of up elevator, even when the cg is spot on. Hand-launching is tricky because of the down thrust. Immediate up elevator is required to keep it from nosing into the ground. Also, don't launch at more than 1/2 throttle. Trimmed out properly, you can fly those Dynam powered gliders way up high, kill the power, and just glide them around. They don't fall out of the sky. I have room for another plane. Hobby Zone had an email offer, $20 off a Firebird Stratos and free shipping, so I ordered one of those. Check the Hobby Zone website-- these are really nice planes and it'll be yet another great micro video camera platform. My pnp Hawk Sky from Grayson Hobby should be here tomorrow. That plane will be the basis for several modifications. I know what to do to improve it in several ways.
