With the lower half of the PVC fuselage cutaway back past the wing to save weight, I also got the wiggling of the tail after snaps. The same with full power spins.Īlso tried a V-tail on a PVC fuselage like a SPAD. I could snap a couple of times and release and watch the tail rock back and forth. ![]() Talk about a graphic demonstration of rear fuselage torsion from a V-tail. I once built a Duraplane with reduced incidence (stock, it has a lot), downward tip plates to reduce effective dihedral and a V-tail. ![]() I'm not a pattern flier, but I do like my fun fly planes to fly somewhat correctly. When you are in a bank and use elevator, one half of the tail is pulling the wrong direction. In an acro plane you want to decouple all the axes so you can use rudder, elevator and aileron independently. You get a lot of unwanted yaw & roll from them. In my opinion, they are fun for a while, but not very good from an aerobatic standpoint. V-Tails: I have flown several and built a few. ![]() We seem to talking about 2 things here, V-tails and anhedral stabs, so I'll comment on both from the standpoint of an aerobatic plane.
