Ray,

Ed did thinking a lot of the way I do, only he did not had the electronics.

The Taurus, is designed by Ed (and Top Flite) to fly with a speed as constant as possible, but there will be variations. (proportional control loop)
The drag of the plane, especially the wing, is greater than normal, so with reduced RPM the speed will be low also vertical.
That's the reason I did use the Taurus to try speedcontrol, engine to accelerate and drag to reduce the speed.
My cruise control works excellent and I do use it often.

So, Where Ed did stop, we can continue.
An other dead end road for him was the proportional, not familar with, but also to big.
Now we have our modern proportional radio and I think his original contest Taurus deserves another change.
That is why!
