I was given the opportunity to build production versions of Art Applewhite's 18mm and 13mm Helix monocopters and some BETA versions of the 18mm and 13mm Double Helix. The latter are not technically monocopters, I guess they are bi-copters. I previously flight tested BETA versions of the Helix monocopters. Art has optimized (simplified) the design and improved performance. If he gets them any simpler, they will be ARF kits (almost ready to fly). We had some terrible storms with a power outage and minor flood in our basement. So, these can even be built while dealing with a minor disaster!
No pics or details until Art announces them. I hope to fly all four at MDRA's June launch in a little over a week from now.
