EDF Control Problems

Thanks, I'll try your suggestions.

Btw, can you pinpoint the correct cg?

I honestly can't remember now. I no longer have this plane but I do recall that on the kit version, it's marked on the wing with an "X". If you downloaded the plans and cut your own pieces, then it might be indicated on the plans with the "X". Here's the YouTube build video and it might give you this information somewhere in there.

Found it, approx 55mm from the forward edge of the main wing (the foamboard part).

I balanced with a 2650 mAh lipo: it has to move forward, partly inside the nose cone, but no extra weight needed. Back to 1225 grams. Now on to measure the thrust, after resetting the throttle range for the ESC.

Thrust shouldn't change on the basis of mah size, only if you're using a significantly newer or higher "C" battery.

I know, I was referring to the programming of the ESC.

edit: max thrust is 0.84kg. Which leads to a ttw of approx 0.7 with a 2650 lipo.
