Printing some frames and experimenting.
Nice flying frog!!!
I like your compact design.
Could you give us some more info? Part size, what 3D printer did you use? What filament? Is stiffness enough or you are getting problems with autotune?
Thank you I am using the CR-10 printers with inexpensive filament, The stiffness is fine but i added a spar in the center arms. i prefer to manually tune the pids normaly just a little reduction of the bad rotations takes care of any issues. Ribbit!
