A model that "lands too fast" is either overweight (and that's easy to figure out) or the engine isn't idling slowly enough or you've got too much pitch on your prop. Or some or all of the above.

My CAP lands about as slowly as I wish. Matter of fact, most of my bounced landings happen because I'm not bringing it in fast enough and I wind up sorta dropping it in, and it bounces. I've got an OS46AX on her and it'll idle nice and slowly. And I'm running either an 11x6 or an 11.5x5 prop most flights.

I haven't noticed mine slowing down much when it's thrown around. If I don't pull the throttle back, that OS won't let her slow down. And she balanced left/right ok right out of the box. I do know that since I've put in some rudder/elevator mix to solve the pitch-down on rudder movement, she flies better. CAPs are known to have a pitch couple coming from rudder movement. A guy who's had more than a couple of CAPs said that the rudder increases sensitivity from aft CG more than the elevator does, but that's just hearsay to me. I've not noticed that... yet....
