Hey all
I started (after 30 years of trying) flying a no control plane it was this one
http://www.raidentech.com/newdesmrarec.html .
I set up the plane using no power, at first all I did was test glides, if it doesn't glide well it won't fly well.
I made all the adjustment for gliding then I powered it up. because of the motor torque it wanted to fly in a circle. because I was use to bending the rudder and elv for gliding I knew what I needed to do.
in the end this plane flew straight at 1/2 power ( all it needed to cruse), I got almost 3 hours of in air time with this plane ( over may flights ) then I lost it.
I had tuned it up so well I lost it in a strong thermal, because of the gentle circle it would do ( no motor torque) it got caught in the center of the thermal.
I watched this plane for 1 hour and 45 min circle UP and UP and UP, it was a speck in the sky, I blinked and it was gone.
SSOO what I would recommend is, do a bunch of test glides, play around with bending the rud. and elv. when you get it to the point of it gliding straight try some short bursts of power
Have FUN
