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.

Testing the weight shifter.

Just tested the weight shifter at skenners. Flew perfectly … in a straight line. Flight weight 836g. Too much lift on these wings. Also the lift goes all the way to the tips rather than being laterally centralised. Thus the weight shift makes bugger all difference in this wing.Using 50mm thick foam sheets as wings is great as you don’t have to laminate them, but then they’re heavy, cause way more lift and require more power, torque, mass movement to drive rhem.
