And the wings are started
I also contacted 4max for their advice on an electric set up
He thinks my weight estimate is way off, he thinks 20 / 25 lbs and has based his proposed set up on this figure, never delt with them as i think they are expensive, dont know how to put his email on here
But his power set is EXPENSIVE

I presume the wing joint position means there will be 4 engines outboard of it.
Interesting that you have set the wing joint perpendicular to the airflow rather than aligned with the sweep of the wing.
Apart from the geometry involved I can't see it makes any difference.

I presume the props were a typo, and you meant 3 blade?
But what is the other line? (or was that the props again - another typo?)
You might find that APC props are cheaper.
Who is the motor manufacturer (PO)
Who is the speedo manufacturer (4M)
Without a name, they can't be looked up for the spec's.

Don't forget you want FOUR speedo's, one for each motor - and 40 Amps is pushing them to their limit, I'd fit 60 amp or bigger.
if you are calm and collected when all about you are going berserk - you've missed something important!
