Wondering if someone can splain me whats going on. I might be missing something

I have a HBFP with training gear on it and when igo out to practice i cant get the skids more than about 5 inches off the ground. Battery has a full charge.

no wind, sunny out, Esky TX that came with HBFP

Is the training gear that heavy that its keeping it grounded? (carbon rods and foam balls)

Thanks for explaining

Steve
