Great engine! Lightweight and reliable, I am using this in my JP Prangster 3D and it works really well. Good fuel efficiency and power.

One of the smoothest running, most dependable and efficient 40's available. It's light weight make it an easy drop-in upgrade for any 28-35 size
plane. I replaced a finicky high performance 32 in a sport-pattern plane and got better fuel economy, lighter weight, and unlimited vertical with
set-it-and-forget-it neddle settings. rnrnMy hands down recomendation for any of the 40 size trainers available as the easy starting, rock solid
dependability and crash resistance quickly make it a student's (and instructor's) best freind. So much smoother than any of the other 40 -46 sport
engines out there!

I have had an AX40 AME for 4 years now. I installed it in a Model Tech Magic 36 because it requires a lightweight engine. I think the AX40 likes to
go faster than what I am using it for, low end torque. It performs beautifully, but I would like to convert it to diesel to got more low end torque
for the Magic.

I have had one of these for a few years but havent found just the right airframe to fly it in yet. I have bench tested it and found it very flexible
and powerful for its weight. Mine seems to like lighter props about 10X5 is very peppy. I have a Shukoi 30 that might be a good match , we shall see.
Another option is the SIG Kobra, it is only a .25 size plane but I understand this light weight engine might be made to fit and provide mega power in
comparison to any .25 out there. I have even heard of one being used on a SIG Wonder, if you dont know, the SIG Wonder is a .15 size plane that was
apparently insane fast with the Norvel AX40
