Yeah, it’s unlikely that this was caused by a defect or a nick in the winding. You probably would have seen jittering in the motor prior to the accident in that case. Since this happened immediately after the prop had ground contact, it’s almost certainly due to getting power while locked up.
One time I had a plane that “landed” on tall grass with the prop facing upward. I thought it would be cute to take off straight up without retrieving it first. Well, there was enough grass impeding the prop that after a couple seconds, it let the magic smoke out. Lesson learned. 😂
man…gods honest truth, thats exactly what happened on the three i speak of. if i am lying we can stand before god about it after i die. i think i even have talked about it in the forums here. all three i thought i had RF interference from my radio being to close to receiver, so i throttled down, started over, held plane as far away with left hand, radio in right, throttled up with my teeth, launch, dead.
i am still going to trust the OPs word that motor was cut before landing. no disrespect guys…in short you are telling him he is a liar. which is exactly how i get treated here if i say something counter to the “accepted” opinions here. legit, no disrespect guys, but rather with as much respect as i can give…have you considered how demoralizing and disrespectful it is to someone who is learning when every thing they say is automatically shot down, dismissed, and told is wrong?
where i fly is an airfield, 7000x4000 feet, the grass is usually 6-8” tall, every time i land, i am throttle at zero, elevator down, you can see the prop spinning from air friction not throttle, plane lands, grass wraps around prop. if i am ever doing a low fly and hit ground or legitimately crash with throttle up when hitting grass, it never wraps around prop as the thrust just cuts the grass and ejects it out.
