I don't want you to abandon speed wing idea, it's really good and scale looking and works fine if you want to fly fast, but it requires a lot of work and skills to do. Undercambered wing will be easier to be done + easier to control. I guess that designing it won't be some big challenge for you
Thank you for sharing this great design with us Nic!
For me this plane was the 3rd scratch build after a FT Alpha and an FT Spear wing, but even with that little amount of experience I found it to be relatively easy to build it following your plans, the build video for P39 and at some points the pictures shared by others builders.
I've build it using xps foam 6mm thick covered with laminating film and at the end it exceeded by far my expectations regarding looks at least and, while flying it is a bit tricky for me because I'm still a beginner, I can say that the controls feel crisp and it flies nice even at the lower speeds that I'm flying it.
Alright, I started building one of these bad boys and have a question about power. I don't really want a speed demon. I have a rs2205 2300kv, and I know that would work. I also have a HURC 370 size 1100kv that might be a bit more tame. Does that 370 on a 9x6 seem like it would be enough?
Also, Nic, if you're still watching this thread, how did you apply the tissue paper covering? Thinned elmers white glue? WPBU?
Seems like it is coming along just fine, the NN designs always take a little more time than the FT models. Also, using gorilla glue to help with the weight, so that takes a little more time.
