Thanks for your note. This gliders platform is based off of Dr Drela's Supra thermal duration model that is winch launched or hand towed.
I significantly changed the build as for an electric assisted model it does not need to be anywhere as strong as his original design.
The name Red Merle I gave it is the color of our Mini Australian Shepherd. I made it a beer as ALES pun just worked well with it.
Plans are available on the first post, I think they are up to date.
