80mm EDF Eflite radian disaster 

maybe just a gentle horizontal launch ? Great experiment 👍

try to mix elevator proportional to the throttle due to the momentum that the engine is creating. And try to launch gentle while running, dont stop running and throw at a stance. 😀

😂 We tried multiple times. It had over 1200 grams of weight added.

Don't get your football playing buddy to hand launch your sail plane. That mistake is on the builder as you should know better.

Dudes... what are you doing.... ? You can not push by hand that hard the plane... The hand is never correctly oriented with the correct plane direction... you will always get 'dangerous' results... The arm/hand should just support with a gentle push the direction the plane is taking during the launch, while at sustained throttle...
