I built my first FT SPITFIRE and when we do the simple overhead throw takeoff it doesn't fly right and flies about 15 feet before hitting the ground. I don't know if it is nose heavy or tail heavy or unbalanced? I have a 2200KV motor with a 8x6 xoar prop. It has a 11.1 volt 2200mah battery. I'm using a FLYSKY FS-i6 transmitter with a FLYSKY FS-1A6B receiver. I'm wondering if anybody knows what could be wrong please help because this is my first FliteTest build and first 6 channel. I've seen the FliteTest YT video on the review and saw how they launched it and we did the same thing but could not get it up. Please help! Thank you!
