I started this in Dec. but waited on parts for a month. I didn’t have the plans for the center board and guess looking at CPO. I’m a 1 1/2 inches longer. Flew once with stock KK board and went to high and lost it behind my house. I cut thottle and went and got it. The left prop had come loose and crashed. Got it repaired and flashed KK board with beginner program. Took it to club fling field and flew two batteries. Stay lower and closer. Wind was blowing about 10 to 15 mph. It did good. I’m happy.
