Rite Pitch props

Post  Oldenginerod on Tue Mar 03, 2015 1:17 am

Just got 3 wooden props as a bonus in an ebay purchase.   Thumbs Up I didn't bother getting a picture of the engine I bought.  It's an OK Cub .099, but has marginal compression, all mount holes broken out, head rounded off and no NVA.   Thumbs Down  But it does have a pretty vintage glow plug.  Cost me $5 USD posted.  The only redeaming feature is that it's a square-back model which I don't have.  It was pictured with a wooden prop installed, but arrived with 3 in the package. The one fitted is a "Power Prop" 6DX5P and looks unused.  It was acompanied by 2 "Rite Pitch" props, both look unused but the smaller has damaged decals.  As you'll see from the picture, the larger is a 7DX3P and the smaller is 6DX4P.  Sorry about the fuzzy picture.

I was wondering if anyone has any experience with these.  They're an odd looking prop with a wide blade & square tip.  Are any of these usable? Are they any good? Are they worth anything? I mainly want them for display anyway.

I'm no help, sorry I've never seen that brand before. They look cool though. Nice for display for sure.

I've never used them myself, but I seem to remember reading last year that they were good sport props. Not high performance by any means, but the guys who used them loved them.

Thanks guys. Doesn't look like they're so common. I'll preserve the nice one, try the one with the decal damage and maybe use the Power Prop which looks a little more conventional, although it is a 5" pitch.

Hi Rod. I really like the way wooden props look on an airplane. I have a bunch of old "woodies" in my prop bag. I don't have any 6 x 5 props. Would those do well on an .09? Is the hole in the hub bigger than a std. Cox 6 x 3 prop? I wonder how a Norvel .049/.061 would do with a 6 x 5... I have a McCoy .098 that I've never run. It doesn't have much compression. I think it has a 6-32 prop-screw and it's prop-driver has a center-boss. I think that I have an old wooden "Rev-Up" 7 x 4 that fits it.

The Power Prop has a regular small hole so will fit a Cox, but the pitch is probably too great for a standard .049. It would probably unload well in flight on a quick airframe. On a ground test it may not show its true potential. It's very light. I don't think it would be suitable for the Cub .099.
