Horizontal Stab stalling/ ballooning?
I have never flown a Cap configuration until my present model. In level flight I give a little rudder and it seems like I must have moved the elevator stick the same amount. It dives for the ground.
Although I expected some nosedown I was still amazed. I have been pulling some pattern ships out of mothballs and (after replacing some motors and radio gear) had just flown a QuickFli III (trivial coupling) and a Curare (small coupling) and they were quite benign by comparison.
In looping and rolling maneuvers and even at low speeds the Cap is comfortable to fly, no worse than a lot of airplanes I have flown.
But considering the rudder coupling and the work required to trim it out I have no idea why someone would choose this airplane given the other designs available. Well I do, it does a lot of things right and is good at snaps, etc. but....... yeech!
