you have a couple oxymoron's going on here. A 232 doesn't glide very well, besides you get your slowest landings under power, if you get it too slow your going to tip stall it or snap roll it in. an FA65 is a 4 stroke. and you can slow the plane down by going to a 13x7 or 14x7, probably a 13x7 since you want throttle response with that kinda plane, just make sure your rpm's are within spec.
