Fried the QX90C mosfet

Yes, by the 4th flight it was baked. The mosfet labelled A08K 77 overheated. I think possibly because we are NoObs at Quad flying and so hovering around indoors on and off the ground without much air movement over the mosfets doesn’t give much of a chance for heat dissipation.

We ordered some mosfets off Ali Express. They should arrive in a couple of months and then we can test our micro soldering skills. Util then we’ve ordered some more QX90C’s and will also order a spare flight control board.

Maybe it’s worth sticking a baby heat sink on these mosfets.

We flew this for the first time on the weekend. We can’t fly quad to save our lives, but it resisted all our crashes. Shows what a lack of mass does for your survival rate. Quads are great FPV practice as a transition to wings. Get’s you used to floating in space and moving around through the goggles without the device moving away from you at a million miles an hour.
