I run a 46 AX on my
SSE. The APC 12.25 x 3.75 pulls my plane like a tractor(after I removed the muffler baffle for that extra little bit of ooph). With your 55 AX it will easily have very nice vertical pull. Sounds like a great setup! Check out some taller landing gear if you go for the 12.25 prop as the stock landing gear will put this prop very close to the ground if I recall correctly. I purchased some gear and bent it to get another 3/4"-1" or so clearance which helped.
My .46 AXes are rock solid once tuned. Start very easily and I've yet to have one die. Running A3 plugs on both. Pondering a move to the A8s.

miles ahead of ya on that one. I just happen to do fabrication/structural maintenence on fullsize planes in the USAF for a living, so i have a whole fab shop at my disposal. in fact i already made some taller gear for my buddy's SSE. since i was looking to get one at the time, i just happened to make 2 sets. so I have that covered. as far as the .55 goes, that came as a suggestion from the same friend who i believe has a .46 on his as well. tell ya what, that .55 ran better about 30 seconds after i cranked it than my super tiger .45 does after countless hours of flight time. I might just turn into an OS convert as a result. I broke it in with the A8 that it came with. I will play around with props and plugs when it is in the plane and i can do some real world testing. I also happen to have a 12.25 X 3.75 APC prop sitting on the bench (the ST .45 didn't like it much). the manual with the .55 says 12/6, 12/7, 13/6, 13/7. so that 12.25 might be a little less prop than it likes. like i said, real world testing will determine that. I do expect some stellar performance out of it though.
thanks for the input.
