I just got my Guillows 20 inch Piper Super Cub 95 in the mail like 20 minutes ago! I had to check out a conversion video to see if it's actually possible, well done.
Don't forget to wax over your plans stopp the glue sticking so that when repairing after crashes plans can be used again.Nice work thanks for showing and yes very valid tip not to pin through the stringers and longeronsetc.Sheet balsa is ok if away from the edge.Try glue in the holes may strenghten up he balsa after pins are pulled out? Be Blessed
I have had lot's g Guillows kits but the one I am working on just now is so bad I had to use my own wing's. The Balsa is so fibrey it is just splitting as I cut it with the blade. Not seen Balsa as bad in my life but from GUILLOWS it is unbelieving to me.
I built one as well, buy used a 2 cell system with a 3000kv motor, a smaller battery, a Eflite 6410LBL receiver and 2.3 gram linnier long throw servos. Your set up looks very heavy. Did it fly? I haven't flown mine yet.
