I recently flew my Funtana 90 with a 150 Saito in it for the first time the other day, and I love the motor so far. I only have one issue with it. I can hover the plane at about half throttle with a 18x8 prop, but if I try to give it anything more than that it won't pull out of the hover. I don't think I am under or over propped, so I am not sure why I don't get any more after half throttle. I bought a tach yesterday and this weekend I will figure out my rpm's.

I am running 15% nitro in it.

Could this be a prop issue?

Thanks in advance for any help!
