My plane pulls to the right during takeoff then as soon as it’s airborne it does a half circle and crashes. Any idea why? It’s 4 channel trainer.
Thanks!
Is it front propeller plane? If it is then you've encounter an effect called "torque roll", its the inertial force from spinning propeller that twist the plane body to the left or right especially during full thrust take-off where not enough wind speed accumulate under the wings to counter the roll of spinning prop. Same effect goes to what happen if your remove tail proppeller from a helicopter.
If its a pusher prop with small propeller behind pushing the plane, then check if the plane tail boom doesn't twist or wag around especially the ones made from foam.
