A while back I bought a really nice looking Tee Dee .051 but was told in advance that it had a broken crank shaft. Sure enough the crank pin was broke slap off. No other damage can be seen. So I have been sitting on this a while and have seen several left hand cranks go across the sales boards and I have had to stop and think more than once, should I try one? I feel like kicking myself for letting on go past for just six bucks...

Two key reasons to consider this. I haven't seen any standard rotation cranks and wonder about availability and price. In addition, it just won't stand much chance of running if I don't do something.

I have seen a few medallion cranks go across the board as well but aside from not being able to get the better performance, would a medallion even run in it? Timing and bore should be the same. Assuming of couse.

For now I have seven left hand props so no problem for now but in the future could be a huge problem.

Robert,

Running a Medallion crank in a TeeDee makes for a nice handling engine. The mild intake timing of the Medallion crank with the venturi and bypass porting of the TeeDee works well together.

Thanks Tim, I had a feeling that was the case, thanks for verifying this. It is nice to know there are choices but inj the end I do need to eventually come up with a conventional Tee Dee .049/.051 crank if I ever wanted to sell it.

For $6 get one and run it for now. In the meantime keep an eye open for a RH crank. At least that way you can run it.

Where'd you find so many left hand props? I'd think these days that they'd be as rare as hen's teeth.

Bruce, the 6 dollar one slipped past me. It was the opening bid and I just didn't bother. Later I saw that only one had bid on it an it sold.

The props I have accumulated over the past few years.
One is a white Grish Tornado 5X3, another is a 5.5DX4P black Cox two blade and the rest are 5X3.5 three blade black Cox.

For now there seem to be plenty so getem while you can!

I can get plenty of the medallion RH cranks for five bucks a pop too for now.

I think I will spring for one of those next week and shipping ain't bad either.

I believe the LH Tee Dee cranks were primarily for the control line speed crowd and probably incited into production by Dale Kirn.

I've taken the Medallion crank with the round, intake port and ground the port rectangular, like the TD crank. I didn't change the timing and it worked as well as a stock, TD crank. Worth a try if you have a steady hand.

Robert,

I think if you look closely at that Medallion crank you will see that it is a LH crank not a RH crank.

cheers, Graham in Ottawa Canada

Graham! You are right my friend! The attention is in the details they say...

I just don't think I have known of any LH Medallion crsnks. Honestly I would not have known by looking at ther product as I don't have one nor have I seen a standard Medallion shaft to compare.

Just the same I may buy one just because the price is nice. I just won't be in a hurry to do so as priority is pretty low right now.

So.... To show my ignorance a couple more questions, one pretty silly.

Left hand cranks were made by Cox for which engines?
Now the sillly one, why didn't Cox offer a .020 in the Medallion line?

Hey guys I have plenty of new Tee Dee cranks in stock. I have RH & LH, I also have the very rare Tee Dee .05 Crankshaft that has the crank pin drilled out and balanced like the Killer Bee's. If you need one shoot me a PM. Oh and I also have plenty of the LH props too.

Cheers, Reggie
