Bullet nose collet style Prop Adapter for 4mm?

I've been digging though all the vendor pages and can't find a nice looking bullet style prop adapter to fit 4mm shafts. Everything I see terminates in just a nut on a 6mm thread. Any ideas of where to find a 6mm bullet nut?

Not talking about a big spinner. See Corsair pic for example.

Not sure if its quite teh size you are looking for, but this http://www.aircraft-world.com/prodde...J-8032&from=63

combine with this...http://www.aircraft-world.com/prodde...J-4703&from=63

And you may be OK, sadly the nut may need re-tapping to M6 tho

Did you see these (bottom of page)? If a true collet adapter is what you need, I'm pretty sure the Graupner bullet prop nuts have the same threads as the hex-nut using collets at the top of the page. Cheap enough to try a mix & match. http://www.hobby-lobby.com/propadap.htm -thumbs

I think thats a 3mm shaft, so if you cuit it back any 3.2mm bullet/collet prop adapter will work?

MPjet do a collet that fits those I think - not sure if their nut fits it tho.

Mmm. they do a 3mm adapter with a M5 thread, and the nut is M5...I think I have both of those - lemme see.

Yup. MPjet 3mm adapter will take their domed nut . Not totally as nice as the Graupner, but good.

So MPJ8030 ot MPJ8031 parts will take the nut MPJ8032. See Nippon Daves site at www.aircraft-world.com for all details and prices etc.

3mm shaft to domed nut.

Use the shorter adapter on thin hub APC props, and the longer one on others. It fits pretty well on the only GWS box I have - an IPS box - and if the shaft on the 300 box is the same thread, it should work well .

I'd try and fill the threads a bit tho - collet adapters on threaded shafts? Hmmm..

Anyway, its not big money, if you want something a bit prettier to try out on the front of a GWS box.

MP Jet 5513

I finally found a M6 prop nut to fit the 4mm/M6 collet adapters that looks pretty cool. The MPJ 5513 from MP Jet on page 11 of their 2003 catalog.

Anyone know who carries a full line of their products? I only see bits and pieces at some places online. And of course nothing at the LHS.
