Hi Kelly,

Thanks for the info.  Yes, I am quite familiar with your airc= raft. I have seen a couple fly at some airshows I used to attend and have a= ctually been inside of them.  The ones I saw had a 180 Lyc with a fixe= d pitch prop.  Once airborne they seemed to perform quite well, but ne= eded a lot of runway to get airborne.  Probably a CS prop would have m= ade all of the difference.

I would recomme= nd our VP2 series prop, a 3 bladed prop will give a very smooth performance= .

Hi Kelly,

Thank you for y= our inquiry. We custom build the blades to fit the application, so there re= ally is no maximum diameter. The diameter is determined by the prop tip spe= ed at takeoff RPM.
