Since you don't know what kit this was built from answers might be somewhat vague. There are many new "CAP" kits on the market of current designs which fly like "pattern" planes. If you look at the designs you will find in many cases they are actually "disguised" pattern planes. The CAP 21 had a fairly long tapered wing which caused it to "snap" at some most unfortunate times. Actually what most of them do is to tip stall and drop a wing on landing. Throttle management is the key to good landings with any plane. It is most important with this type of plane and with most "warbirds" which have small flying surfaces (fin/rudder > stab/elevator) arrangements. The placement of the stab in front of the fin makes the elevator more sensitive to input (pitch sensitivity). If you give too much elevator on landing the plane will just stand on it's tail. Elevator must be relaxed and power applied to avoid this (assuming it didn't also tip stall and go in already). Try landing approaches high enough to recover from a stall and learn the characteristics of the design. In the air the CAP is my favorite aerobatic plane. Nothing else tumbles like a CAP. Yes I am a fan of the design and own several from a Midwest 'Lil CAP to a 40% Carden. Enjoy, Bill
