I agree with Bob. The choices are to use a P30 prop that requires hours of scraping and doesn't have enough blade area or use one of the Ikara props. Indoor models are fragile by nature. When you get a P30 prop down to the weight of an Ikara prop it can be pretty fragile also. Either one performs better with a rigid prop shaft and a decent bearing.
The prop/bearing assembly that results from the modification I suggested can be tuned the same way you would tune any other indoor duration prop. The shaft can be bent where it enters the prop to equalize the pitch and tracking. If sloppy plastic bearings and freewheel hubs were a good thing you'd probably be seeing them on Nats winning LPP's.
Note in my description of the shaft and bearing modification I said "this is the way I do it". I'm not against any scheme that you like or that works for you.

Junk? I totally disagree. While it's true that they are somewhat fragile and
often need balancing and repitching, it's clear that many excellent Wright
Stuff flight are being made with these props. Overall times are up from
years past. The students I've mentored have done well with Ikara-equipped
models. I'm flying my Comet Phantom Flash ROG with one. It took third at the
2006 FAC Nats and flies well indoor as well.
