RE: Help! Need "first principal" assistance
The first flight I had was a disaster. The glider had hardly no power with the speed 600 drive train I was using from FMA Direct. It started sinking after a hand launch and hit the ground with a hard belly landing. The tail elevator snapped off. I was warned about this glider's weakness in past reviews.
I upgraded the motor to a 8.4 V Ripmax 600 Litespeed geared motor and used a bigger prop that was supplied with the motor. I also made sure the tail wouldn't break off too easily. I have reinforced this with 2 triangular fillets of balsa each side. The climb was good at about 30 degrees and the glider flew really well. From this experience and past gliders I've had I recommend upgrading the stock motor with a gearbox and a bigger prop.
