Hello,
I have become proficient flying a HZ Super Cub. Felt confident enough to finally step up to an EDF foamie. Put together a Phase 3 Fantom EDF, a delta wing edf with twin vertical stabs and elevon control surfaces . Sadly it crashed on take off during maiden. Following a level hand launch at full throttle, I pulled back ever so slightly on stick to gain abit of altitude. The plane rolled over on its back and nosed right into the ground. The fuse is badly damaged, in more pieces that I care to count. CG and elevon throws were verified prior to flight. Wind was calm. Flying 2.4GHz. What did I do wrong?
