Nic, your plans are great and really well detailed but speedwing isn't working too well when you're just flying on FT pack setup. Stalls are pretty common when on low speed :/ I made some planes designed by you, mini P-39, 800mm MiG-3, 1m Ki-61 and 800mm Chipmunk with undercambered wings - Ki and MiG-3 were really nice to fly unless I was doing stupid stuff like hammerheads, spins or inverted 1 meter above ground
the chipmunk was really easy to fly and it looked great (until my brother crashed it lol) I'd love to make and fly planes designed by you but with FT style wings (undercamber). I'll be really happy if you consider adding undercambered wings for your plans
Keep up the great work !
