I don't get this. The airplane is either flying or it is stalling. There is no in between these two conditions. The only exception to this would be in 3D flight when the airplane is in a stalled condition while hovering. If you lost a side in that attitude with no airspeed you're pretty much out of luck. I don't use choke servos (though I did give it serious consideration) for one reason...a bad pot can leave you dead stick. In a meet that can really cost me. In practice it's possible to come up short of the runway. I really don't like dead sticking these big planes, and have never had to with the exception of the meet last weekend where I lost the side...actually it was not a true deadstick as the airplane was at low idle, but it wasn't really pulling any. It really would've been better if it had gone dead actually as it would've went farther and I could have brought the airplane a little closer to me on landing. hehe If the airplane has too much speed to land it is still flying I could easily fly it out of gas. It may be hairy getting altitude, but if it has speed that can always be exchanged for alititude. If the airplane is stalling, altitude can be exchanged for airspeed. If there is no airspeed and no altitude, the only choices left are to land or crash...hopefully not crash! In any of these circumstances a choke servo really will not help matters, and is why I opted not to use one.
