Hello, Roary m

I put 8 flights on my U-Can-Do 46 today with an OS 50 AX mounted inverted, and had a great time. The engine uisn't totally broken in yet, but performed well. I used a 12-4 APC prop and will play with other props later.
Yes, I fly the Ucan with an OS 91 pumper which I need with floats. I take the floats off and fly on grass also. If you get in trouble trying to hover, the 91 will pull you straight up. I use 15% cool power.
I will be trying to do the rising inverted flat spin. I will probably wet myself if I ever get it done. I know I won't do it with the 50AX
