There's a bit of polyhedral, it's up to you how much you want to build in depending on the performance you want. Tail is programmed as a v tail.All right, I have all the parts cut and ready to go. Is there dihedral or polyhedral in the wing? Did you set up the tail as a v-tail (programming wise)? At this point I’m trying to decide between an 1806 or 1407 motor. Either way I was just going to use a 900maH 2S as both the motors are pretty high Kv.
