I was telling MinnFlyer and I believe RCKen that I decided to use the new OS 75 AX. After my experience today our uncut flying field, I made 6 attempts to fly, two were successful, and I spent a lot of time walking down to the end of the runway gathering my plane because it could not get enough speed to take off. That won't happen again. The Protege will get the .75.
CG,
I'm in the process of doing a review of the 75 AX for RCU. I can tell you that if you put this in this plane you're gonna have an overpowered rocketship!!!!
It's a very strong engine that uses the same bolt pattern as the 61 FX. It's a nice engine though, you'll enjoy it!!
