To SRA Foam Flyer, as you can see from my post, I flew the plane STOCK (the kit) and it flew WONDERFUL right off my hand at almost 45 degree UP. 8/cells, 600MA did just gooood, not HOT after fly and so the motor (the 6V). I din't add ANY weight at all, like I said, I split the 8/cell battery pack, 6 right after the aileron servo and 2 cell up in front after I dig lot of foam in front of the canard. I keep repeating this because the plane is GOOD, I don't care what ANYBODY also said! Aldo
