I finished my test jig. It looks pretty good.
What it is: just two 2' long 2x4 pieces of lumber. Around these are these 4 'springy rings' I made from scrap iron clothes hangers.
The foam training gear balls just fit under the rings. One for each. Now then, there is no freaking way this heli could lift those 2x4's, but I put two more 1/2" boards across those! Suffice to say, we are totally anchored, but the rings allow for a few inches of movement. I really doubt the heli could tear its skids out of the training gear attachments, either. Let's hope!!
Ideally, I should be able to hover freely just an inch or so off the skids, but be unable to blade strike or move off the wood bars.
I'll take a pic when its ready. If this works, I'll recommend it for any Maiden flight on any kind of small experimental aircraft or any newbie looking to get a feel for the micro heli controls in the living room with complete safety.
Muhuhahahaaaa... [>:] * batteries charging *
