RE: How much pitch control would elevons provide
It is done except some buttoning of securing balancing weight and wires and final gluing of wings into fuselage. Wing area is 351 sq in and weight is 9 oz for 3.7 oz/sq ft loading. CG is 1.93" aft LE for abt 30% mac. Btw it required 10 cents (pennies) to balance. If elevators are not needed, it will lighten up a good bit as the elevator servo is somewhat aft with wire linkages and these offset by 2-3 pennies.
The config does use three ch, with two for elevons and one for elevator. The elevator is switchable in and out with the mix switch to test possibility of not needing, which would simplify RC conversions.
I'll report back after testing on whether elevons offer enough pitch control.
Just remembered I need to check to see if the elevator trim will follow the mix as it is plugged into the rudder port on a 4ch RX.
Tried to upload a pic... server not taking it... will try another route and provide link in a short.
