Wanted crankshaft for Tee Dee .020

Thanks for the encouragement. I will keep looking. Thanks again. Jim

Jim,

Consider a used engine. The market currently is on a down swing and I have seen things go pretty cheap. That way you have your crank and spare parts.

Welcome to the forum.

Ron

I think you are right. I am going to keep my eye out. Thanks, Jim

I will try to find him. I have a search saved on ebay. That should help. Thanks for the help. Jim

About 6-8 months ago Dan had TD .020 crankshafts on a BIN acution. I bought the last one - or so I thought. I get a PM through eBay from Dan that he could not fulfill my order as he did not have any more. He refunded my purchase and I eventually found one on eBay that was NIP.

Thanks Jason, it would appear ebay is my only hope. Jim

Or parts lots that have a bottom end of an engine. Every now and then parts lots show up on eBay. Some hidden gems if you know what you are looking for.

I have yet to stumble on the "coffee can" full of Cox parts engines at a swap meet.

Here is my ordeal on looking for a TD .020 crank that started in 2012.

I also sent you a PM.

california-dream is Dans handle at the moment he is selling striped down engines and parting out them to eek out max bucks its a shame they go this way just for the dollar but he does have Cox parts and its just a matter of time before he has some TD cranks for sale. He will part out portions of a engine hold the rest of the carcass back for 2 or three months then toss out some more crumbs for the folks till the engine is no more.

Many of these engines were ravished up and hoarded by the free flight crowd. I would think that a search for free flight clubs may just turn up something. Ken

If we were to entertain the thought of manufacturing 020 cranks, TD or PW or both? And, what would be a price-point for buyers to actually by the things?

I bought a NIP TD .020 crank in back in March for $55 on ePay.

The better question is how many TD .020 engines are out there in need of crankshafts? Mid to upper $20's might catch some sales to resurect an engine.

Pee wees are in need of backplates most of the time. The crankshafts do break easy on these though.

More folks have a few Pee Wee's on hand most would rob the piston / cylinder and glow plug off the engine to put on a retro lower end kit for a TD .020.

Cheaper could be a simple Medallion retro kit less parts to produce.
Cheaper still would be a Pee Wee with a retro kit consisting of a rear aluminum assembly for a throttle carb body back plate with the same footprint for the mounting screws of the fuel tanks back plate. The existing needle would be used / the tank and back plate would not.

I took a TD backplate the idea is to butcher the Pee Wee aluminum fuel tank to put in between the backplate cut out to allow the intake tube to pass thru cut the tube down and mod for a needle body and venturi off a TD.

Imagine this manufactured all aluminum with a throttle barrel carb integrated rear induction reed with same footprint as the fuel tank back plate to retrofit the engine. Many would mod there Pee Wee's there are soooo many out there.




Second pic is a typical space hopper idea less the throttled carb.

The upswing more fuel and air for more rpm.

WELCOME to the Forum Jim, I dont have one but there is a guy on the bay you mite want to contact to see if he can part with one or find you one he a very nice gentleman .. http://www.ebay.com/usr/thomasjconsulting  , and yes the priceing has really gone down right now i have tooking a whipping But i guess i will wait it out till things get better Eric

Jim,
Think you'll really enjoy this forum.... You're looking for something extremely rare in the TD/020 crank. I got a new in the pack one off Freebay about 5 years ago for $5.00 on a BIN about 3 minutes after it was posted! Don't think I've seen another since. It went into a TD that I got from a free flight guy who used it as a lawn dart.
About 5 years ago a guy in the Atlanta area got the remainder of the Cox R & D department inventory and even he didn't have any TD .020 cranks. I know because I spent a great deal of time looking for one.
I did pick up a LH TD .020 crank at the Perry , GA swap meet 3 years ago from an old time CL guy. He said Cox only made 50 and of course I paid too much for it..
Have a good time in the forum and the hobby...
Steve.....

This is his .020 parts page there are curently TD .020 parts there no cranks worth keeping an eye on.

Is there a consensus that TD 020 cranks would sell at, say $14.95?

That price is reasonable for owners who have this engine and if not to have an immediate need for a crank may opt. to buy a spare to have on hand just in case. Low risk limited run within reason as I would imagine units will be sold slowly to depletion over the course of some years. Perhaps 100 -150 units tops. I own 6 TD .020's 2 in use 4 spares for future projects.
Another option to want a spare is to have one to trick it out for more rpm.

I'm guessing Bernie's price is based at 1k units min.

More like in the 300pcs range.

I would imagine / guess there are about (safe est.) 2500 - 3500 engines still in running condition and about 30% in use or on a plane. If there is a known total production number floating around would help. Knowing there is a spare crank available could have most being more brave to use them in the air again.

You could take all TD .020 sells related to parts Bernie to extrapolate activity least on your end. Perhaps Matt will collaborate on his end then add a percentage on public sales of parts and on ebay.

World wide counts - it is difficult to tell one thing is for sure these smaller TD engines have always been looked after by most. Many have prompted themselves to try the engine on a plane the enticement to do so is human nature.
