1/2A props

Besides APC, who still makes a decent selection of 1/2A props?

Graupner "super-nylon" are good props too that are still being made, same design as 30 years ago...

Cox props are also being made again, go to coxengines.ca

Thanks, you two. I had forgotten about Master Airscrew for some reason. Senility I suppose. I had already looked at the USA Graupner site but didn't see any small stuff. And I have no idea what all those acronyms are. CAM??? CFK???

As for Cox props, I'm surprised! I had no idea that Cox International was actually making Cox parts again. I thought they were just selling left over parts. Makes me want to dig out my box full of 'em , clean 'em up, and play with 'em again!

Bernie who owns Cox International is producing quite a few parts and is planning on more stuff.

By the way Geoff, what are you thinking for sizes?

You can find the Graupner range here; Graupner.de

They have a lot more than the Super Nylon ones now, there are also props with svept tips (CAM) and their speed props that go down to very small sizes too.

Sizes of WHAT???
Engine-wise, I've got Cox engines from an ,010 to an ancient Space Bug to a mess of Babe Bees, Tee Dees, and an Olympic .15 that needs a reed. It seems the Canadian outfit is not selling reeds for .15s. :-(

What got me interested in 1/2A again is having obtained a diesel head for my NIB Norvel .061. I want to break the Norvel in on glow, then switch to the diesel head. But then I dug into my pile of small engines and found all those Coxes, two AP Wasp .061s, and a Norvel .074. Soooo, I've got a whole heap of 1/2A and small A-size engines doing nothing. May as well put some of them to use.

BTW, since you're in Corvallis, have you run into Luke Middleton? He's the moderator of the sticky on Ivan Pettigrew designs in the Scale Electric forum.

Geoff,

I fly mostly free flight, and a little bit of electric R/C as of lately. I have not gotten back in touch with the Corvallis R/C club. Maybe I ought too. I don't beleive I've met Luke.

Not sure he's even i a club, given that he's been really busy of late.

I bet you mean prop sizes! Duuhhhhh.... 5.5-3, 6-3, 6-4, 7-3, 7-4 ought to cover both glow and diesel.

Geoff the ex-Portlander.

No need to buy a reed for the Cox engine. Just crack open an old floppy disk and cut one out. It doesn't have to be exactly shaped, it'll work. Floppy material is a bit thin but it'll work for a while. Better Mylar can probably be found at an office supply store in the copier paper department. That stuff will be as good as the original reed. Don't try to cut stars, just cut round cornered rectangles.

Oh, so you used to be geoffinpdx huh... Those prop sizes should be ease to find as long as you don't mind triming some down a bit.

There is also an APC 5.7x3 that works well on cox .049 engines, it has a little less load compared to the wide bladed cox 6x3.

Steve Wilkes of Eliminator props (going from memory) has some single blade props for a bit more money than the garden variety, and there are some Russian fiberglass ones available fairly cheap if revving up is your thing.

Yes, George, I switched names when I moved from Portland (airport call sign PDX) to rural Indiana. Since I don't live in Indy I can't be GeoffinIND.

Thanks, y'all, for the prop info. My initial post said, "besides APC," for a reason: I threw my kitchen knives away and now use 10" to 14" APCs. Them there props is sharrrrrp!
