Thanks Oliver !

Yes, my initial impression was also that they looked fine, just needed confirmation from a pro

The receiver was "mounted with a showel" inside a small (but very fast) delta wing (1,3 Kg, with a 9x8 prop running at 17K RPM), and I regard this airframe as "a no loss" should "something" happen

Both flights was actually going out far away (at least 400 meters to each "side"), I choose this plane also because of the "easy to see" shape, so I know I can follow it far away.
I will play a little more with it, and then mount one of my 12 channel micro receivers in my P160SX powered Elan, that one consumes a lot of airspace pretty quickly

Thanks for your help (and especially this thread), it's much appreciated, and very comforting with a group when this new technology comes out!
Now, if just Weatronic would step up to their customer support, and start answering emails !?!?!
