Actually it looks like 9x7 will give me much more airspeed with a little less thrust and keep the amperage at about the same level that it is now. The prop will be stalled until the plane hits about 5 mph or so, but I don't think this will be a big deal at all. Plus, the 9x7 will fit right on my gearbox without an adaptor.

Hi ho, hi ho, off the the LHS I go...
