After the first crash we replaced the prop. Thottle was at zero and not armed. Connected the battery and immediate smoke from the motor then ESC caught fire.
Yeah, so what happened here was that the initial crash stuck the motor and overloaded the ESC, fusing one or more of the transistors into an ‘on’ state. Normally, there wouldn’t be any electrical flow from the ESC to the motor with the throttle off, but the blown transistors were just dumping that current right into the motor, but not turning it because it wasn’t timed. All that current burnt the insulation of the windings of the motor first, and then the ESC got hot enough to catch fire. That’s tough, but it gets better! Fwiw, you can usually tell a blown motor or ESC visually. For a motor, look at the windings. They should be shiny. If they’re dull or black, it’s a bad sign. I’ve had a few that have gotten hot enough to turn dark and still work, but it’s a crapshoot. For the ESC it’s usually more obvious. The shrink wrap will usually visibly melt.
Good news about the Tutor. The COG points are pretty good out of the box. The Tiny Trainer is a little off, causing some difficulties with that model, but you don’t have to deal with that on the Tutor.
Where do you live? Somebody from the forums might live close to you and be able to help in person. I’m in Madison, WI.
Good luck! Post videos!
