Your needle hex should look like this, you have the old carb there.

Have you run the motor yet? I have two "old" style TT.53s running on CP 30% without an issue (no shims, original carb). One of them has about 8 cases of fuel through it. If the motor doesn't work properly, contact me via PM and I can get in touch with the Canadian dist. on your behalf.

Cheers,

Colin

Hi Colin,

No I haven't run the motor yet, but would rather not have any issues with it. As long as the dist replaces it once I do have issues then that is ok.

I will try breaking it in with 15% and see how it goes. Since I live in Winnipeg and don't like to fly in -1000C I won't find out for a while hehe.

Should I pull out the needles and locktite them (air dry)?

Thanks for the help,

Ron

Hi Ron,

I wouldn't loc-tite them unless you need to. The low end is the only one you'll have to worry about. If you feel it moves too freely then you can use a bit of blue on the last few threads. Mine is a little loose, but it hasn't moved in flight. Putting loc-tite in that area could create a problem that you wouldn't have had without it. I'd suggest running it as is for now. If it moves then a bit of loc-tite should hold it.

Keep in mind your older style of motor has the same warantee that the latest motors do. So if you run into any issues HCC will look after you.

I feel your pain with the cold... we had a few days last week that were -40

H3N
The only needle that needs the loctite, should it be loose is the one that is in the carb barrel.....

The now infamous Hidden third needle...... We need an acronym for this thing..........HTN H3N ??????????

I'm getting this sinking feeling that someday somebody might loctite all three needles into the carb and then be upset with the complete lack of tunablity that would cause.

Burned through another tank last night with no issues, super consistant run

yea, you have the old needle like I did. I got mine from a high volume dist. So I thought I would get the motor with the new carb. But ended up with the old carb and no shims. TT gave me the new carb in less than a week. But no shims.
Should I try and break this motor in with cp30 or should I wait until I get the shims.
Thanks,
Bob

At this point I'd like to at least find a reliable source and part #'s for the TT shim pack...... so we at least have more options in tuning.....short of cutting them out ourselves.

I second that. If I need a shim I would rather order it instead of punching one out.

Where did you get your bearings, are they stock TT or did you use an aftermarket brand?
Im just using original TT53 ones from the LHS. I got out for a flight with new bearings and the extra shim, so now thats both .004 & .008 shims on 20%. First thing was that i had to lean it out because it got richer i think its due to the .008 i added. It seemed like some vibes were gone but its still not 100%. I did realise there was a slight loose of power and the idle seemed to be slighly rougher, it sounded like it was predetonating. Before the extra shim in tic-tocs the tail would wobble out going from + to - pitch and back. it doesnt seem to do it as much although im still testing it out. I will keep on flying it like this and see how it goes.

hi
Im using CP 30% with the new carb..

NO SHIMS... My power is simply ballistic with 14 -14 pitch curves at 2200 RPMS..

Im having absobutely NO issues.. I dont know why Redline would NEED shims with 30% cool power...

I absobutely LOVE this engine.. I should add, Im also using Hatorai 523 muffler...

20 tic tocs in a row and this motor keeps asking for more like it wasnt being worked enough.

Crash-Prone and overcoming it!!!

I am realy confused about this, in the UK there were no shims when I recieved my TT53 with the new carb. A lot of people are reporting great flying with the shims added and it seems that quite a few are having great experiances without them as well!

Any other UK users care to comment?

Today i went out for another fly. Tail wobble in tic-tocs is gone, it is holding more solid but it just seems to me that there is a slight loose of power still. I noticed with full power climbouts that at the top of the climb the tail would wobble aroung abit. Not too sure if im going to leave both shims in there as im thinking of taking the .004 out and leaving the .008 Its all trial and error i guess as to what suits the flying conditions fuel and so forth. If i do take out the .004 shim i will let you know how it all went.

Cheers bboyy

I'm still running mine with .004 and have a few gallons through it now. She's breaking in nicely and seems to be gaining power as I go. I'm thinking of trying some 30% with this shim and see how it runs with that. Right now 20% CP is $30 and Wildcat 30% is $30 so it might be worth the switch. Either way its making lots of power. I think running both the .004 and .008 is a bit over shimmed as .004 is recommended with 20% nitro.

Rajesh The STD head shim in my older 53 measures 0.43mm (this motor came with the old carb and no aditional head shims)

The STD head shim on my new 53 measures the same 0.43mm (this motor came with the new carb and 2 x aditional head shims 1 x 0.1mm and 1 x 0.2mm)

Hi everyone

I just asked Thunder Tiger Europe about the application of various shims. I don't know if this will help any one of you...

I'm using 30% nitro for 3D performance. So they told me to add the 0.2mm shim additionally first. If the adjustment of the carburetor is still too sensitive I could add the 0.1mm shim as well.

Here is the original answer from Germany:
"bei 30% Nitro sollten Sie zunächst die 0,2mm zusätzlich mit einbauen. Sollte das Einstellen des Vergasers damit dennoch sehr sensibel
oder kritisch sein, können Sie zusätzlich noch die 0,1mm Scheibe einsetzen."

Greets from Switzerland,
Dodi
