I compared weight to HP between all three, and for the HP vs weight the 55 AX won the battle.
Actually it didn't. You cannot calculate with
false advertised data and get any true answer. Tower shows OS specs:
Power Output: 1.75 ps/16,000 RPM
How long do you think the nickel liner will last at 16,000 rpm on that engine? Did you use a tach to produce that 1.75hp @ 16k?
What size prop do you think Tower used to achieve 16k RPM? Probably had a pitch of 1, or less. How much flying do you do in a Decathlon at 16k rpm?
The Decathlon flies fine with a .46, it's basically a trainer in disguise at low rates. I thought the goal would be to fly it scale?
Watch out for those weak tail wheel assemblies on all Phoenix models.
