FFS people. If you want to do aerobatics, GREAT, go use a proper plane and get proper training from someone who knows what theyre doing!!! as an AVID aerobatic pilot, and knowing the forces and what a botched maneuver can lead to, id be TERRIFIED to think to try maneuvers in a plane not built for them!!
it makes me cringe every time i see videos of people rolling planes with horrible technique and no clue what theyre doing. sad this kid found out the hard way.
GET PROPER TRAINING / USE A PROPER PLANE FOR AEROBATICS.
if i found out someone had been rolling a plane i had to fly next, id insist on them paying for a very thorough inspection first!!
note: im not accusing here, just saying if anyone gets a wild idea to do stuff like roll a plane thats not built for it... DONT DO IT.
