I need some advice from the experts here on how best to solve the stalling problem on my scratch built canard. It trims out nicely and glides beautifully on hand tosses but porpoises like crazy when launched. I added nose weight and it helped some but it still dives and recovers in large 4' loops. I used an online CG calculator to get an estimate and it's within 1/8" of where trimming tosses result in a nice glide (also input a 10% static margin). The canard wing is airfoiled and fixed.
From what I gather on other forum threads the canard's incidence may be too much (it looks like it's at about 5° or 6° instead of the 3° it was at before I reglued it back on after it snapped off on a trimming toss). I can either add more weight to the nose (simpler fix but adds a ton of weight) or rip it off and put on a new one at the correct angle. Or I might be diagnosing the problem wrong. If it isn't already obvious, I'm a total newbie at this so any advice/guidance/suggestions (in layman's terms) would be very much appreciated!
