Demon Cortex Glitching In G.P. .40 Sized Cap232 - Help!
Hello Folks,
I purchased a Demon Cortex last week to try in my G.P. .40 sized Cap 232. I followed the
instructions, got it all installed, and it seems to do what it's suppose to do until I start the
engine. I have an S.K. .50 in this airplane. The gyro seems to just jump all over the place
throughout the RPM range. I obviously cannot fly it like this.
I have the gyro mounted on it's own platform, just above the receiver, and used the thicker
of the two supplied mounting pads. It is mounted inverted, but I set it up for this using the
software programmer tool.
Can anyone suggest what I need to do to try and get this thing to stop glitching do to
engine noise/vibration? Do I need to add more foam padding under it to help dampen
the vibrations? Is there settings I need to change using the software tool?
Any help would be greatly appreciated, I would hate to have nothing more than a $300
fancy paper weight!
Thanks,
Patrick

Hi Patrick I have three of the Demon Cortex standard model, not the Pro. Two are in turbine airplanes and one is used in a glow powered warbird. I think where you may have gone wrong is to mount the unit inverted. I think it imperitive that you mount exactly in the direction and orientation pictured on that little instruction card. In addition as close to the aerodynamic center of the airplane (this is near the CG) as possible.
I do not use the patch cord at all. Instead I just do the little stick dance decribed in that one little paragraph on that instruction card to allow the cortex to learn the airplane. Each move ot the stick dance a tiny little movement of the respective surface will glitch just once.
