We found the Zero flies better between the two, but then again the corsair may be a bit heavy in comparison due to the complexity of the wing. Only my ol' man has the corsair however, he made it before I could trace the plans onto a sheet to scratch build one. So I only got a zero while he had both.
I am not holding my breath on plans being released soon due to simple stick STILL being delayed, I really wish they would give some kind of announcement on why or when about that, but I get the impression they may be holding out on releasing plans for several months going forward with all their planes instead of just one month. Business and needing funding after all.
We fly ours on a "F pack" equivalent motor, paired with a 950mah 3s lipo. which fits great in the battery area. The Corsair has a 6x3 prop on it and my zero has a 4" 3 blade prop.. I actually threw a 2700kv motor on my zero, and it absolutely SCREAMS at full throttle!
Neither plane did we bother with rudder, saves weight and we found we never really use the rudder on the mini series planes, they're just too much fun as a bank-n-yank with ailerons and elevator.
My biggest complaint about them is the flat bottom tail looks terrible. you CAN round them out by curving the bottom corners of the former pieces, and cutting the rounded foam piece shorter to match, it's a pain, but the end result looks 200% better I believe. Also yes the default way the servo wire goes is a bit more of a bend than I feel is nessesary, maybe it helps keep it steadier this way, but I also straightened the pathway out so it's easier on the servo.
We BOTH agree however, that the New corsair flies much better than the original mini corsair did. lighter, and more forgiving characteristics. Also the battery hatch is a vast improvement.
