Excellent! Will be watching to see your progression.
What transmitter did you end up getting? [Never mind, I see you went with the Hitec.]Question: For delta wing elevons, what mix of elevator to aileron do fliers suggest?
For RC setup:
As suggested in kit instructions have both dual rates and exponential set up.
Question: For delta wing elevons, what mix of elevator to aileron do fliers suggest?
Kit instructions call for each to be 50%, but some online references suggest more like elevator:aileron on the order of 4:1.
Primary motor: G64 or G80
The stiff, rigid airframe and strong elevon hinges should not have a problem with the estimated 165mph peak launch speed - straight up. This will allow me to use common, low cost G motors and standard rail setup.
If all goes well on the first few flights, 2nd/3rd stage: D11 or D12
At an HP launch would use E9 for 2/3 stage. Can't Saturday as total propellant mass would be too high.
2nd/3rd stage relay switch triggers at about 80% deflection, so sensitivity is perfect for this application. Set the lower dual rate that I would have set for liftoff to 0% for this channel for safety during launch prep at the pad. Confirmed that rudder stick will not trigger relay at all at this setting. Also confirmed that powering up, or loss of Tx signal also will not trigger ematches.
After main motor boost is done, flipping elevator dual rate enables rudder stick's ability to fire one ematch at 80% right and the other at 80% left. One side does double duty and also activates buzzer.
Boris, it looks very twitchy, maybe throws are too high and cg a bit far aft, it looks like you never were really able to get it trimmed and gliding in a known attitude...Just based on the video. Maybe a G-40 or G-33 would give a slower boost. Even in glide it looked like it was really twitchy, more in roll but also in pitch.
I'd say you were doing pretty well to get it to land inverted flat...
Is that what you felt?

In addition to balance, would the flat surfaces on the front of the glider and thick airfoil of the wing also make it more vulnerable to the effects of the wind?
of course you know that batteries don't do well if they get cold(below 40F).
Thank you for the input gentlemen.
However the servos were very active fighting a losing battle with the wind and this was at the end of the second flight.
