Fastest reedy??

This is from the info pack that came with the plans. Building one is on my "to do" list.

Here is the start of one, it didn't sell         http://www.ebay.com/itm/COX-TEE-DEE-049-WITH-COX-SPEED-PAN-/281381069629?pt=Radio_Control_Parts_Accessories&hash=item41839e633d&nma=true&si=HqZklAIW4lYNs98%252FulUFR%252BEQg5M%253D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557

Crank,
Thanks for the heads up but I already have one. Picked it up in the used bin at the LHS for ten bucks

The Seeking Mark

Mark, search. 1/2a speed on eBay .

This is just two examples, there's a lot that comes up .

$45 for a Cox pan with a TD and it didn't sell? That sounds like a pretty good deal to me, was there something I missed (or just don't know)?

The Wasted Mark

I've been thinking something like that would be fun too, Mark. The reed speed contest really has got me interested in speed flying, just not enough to get serious about competing!

Dare I ask what you'e chosen this time, or is it going to be a surprise?

What is the best reed material to use that can handle / provide high rpm?

While others may work OK, the mylar reed had shown me 24,500 RPM steady state on the test stand many years ago...  One was used to set the current AMA national Open Mouse Race record back in 1999. Can't go wrong starting there.

BTW, that was with a Cox 5 X 3 prop (if I recall right). I would expect an APC 4.4 X 4 would turn up significantly more. Lord knows when one crank sheared at the splines the RPM went off the clock for a short while... I would think in the air (with the prop unloaded) there would be several thousand more RPM. I never endevored to measure the in air RPM though. Would be interesting to know.

Imagine if Leroy had took a look at the Pee Wee and said lets make a Lil Wee .010 reedy.. the question of rpm abilities - perhaps 27k???

He did but there were issues with it. I believe the issues had something to do with the reed floating at such high speeds. Mud has some of the parts from it https://www.coxengineforum.com/gallery/Personal-album-of-Mudhen/Reed-Valve-010-Engine-Parts-pic_196.htm
