Hello,
I am sizing the model for these motors: wings span, area, moments, tail configuration etc.
David Felinczak uses 2820 in his Legacy but he wrote that this plane was "heavy at 58.1 oz."
Cobra 2826/10 and/12 are a little more powerful than 2820/12 or/14 so the plane of Legacy size weighting, say, 54 oz. should fly well, I suppose.
As usually, I would be grateful for your suggestions and comments.
Regards,
Matt
