Hey Bill, I have had to goose the throttle several times on landings but only becouse this plane slows down so well I thought I would stall it if I did'nt. I was running a Menz 22-10 for a while even on break in, which I'm still doing just over 2 gallons later, but I had a little crash and broke my prop so I went ahead and threw a NX 23-8 on it becouse alot of people say this is the prop for 3D with a DA50. I thought it might be a little early to do so but I got to say this thing pulls verticle better than ever! I'm not sure if it's becouse the mototr is coming around or just the prop itself but my uplines are unlimited pretty much and I'm loving this combo. On up lines my Edge wanted to fall a little toward the nose does yours? How about knife edge? Does yours roll as well as pull toward the gear? I got a new stab and elevator set after mt little crash but only changed the left side. Afterwards I noticed that the new elevator tappers off from the inside to the outside at a different angle then the original set. I flew it anyway and did a couple of loops to make sure it would'nt snap out becouse of this and it was ok. I am going to change the other side now so it matches. I guess they changed the design of the elevator. I dont know if thats causing my upline pull or knife edge roll or not thats why I'm asking if yours does it. I did'nt notice it before the left side was changed but then again I was mainly just trying to run fuel through it for break in and was'nt doing much more than flying in circles at the time.
