Well I upgrated my Hawk Sky motor to a Grayson V3. It took off like a rocket at 1/2 power.
I gave it full power, went vertical for 100+ feet and the motor blew out of the fuselage. Luckily broke a wire and it shut off. Did adecent dead stick landing.

I'm now trying to figure out how to put it back and have it stronger.
So far I'm planning on epoxy and zip put ties thru the motor cowling and thru the wing <font color="#1d7cfe">slots</font> reinforced with tougue blades.
Any other suggestions??
