I've had both... OS ran great always. The TT53 is now sitting for inspection at Ace Hobby. I couldn't get it to run right at all.

It seems the TT53 is more difficult to get dialed in but those that have got it running good really like it. Mine either ran to rich or when it was running great seemed to be too lean.

If it was running great , what makes you think that it was lean ?

At the end of the day , it gets dark .

When I landed the red head wasn't red anymore... it was all discolored. When I grabbed the temp gauge it read 230 but that was about about 2-3 minutes from shut down.

I know it was running rich prior to this because it would bog really bad. I then proceeded to lean it out a few clicks at a time until it ran great. When it ran great I flew out the tank and landed to see the discolored head.

The .53 gave me a little grief untill I checked the 3rd needle.

it was open 1.5 turns.
I set it at 2 turns and now this baby rips. PERIOD END...

It is an excellent motor!

it idles awesome, makes a ton O' power
and after ripping it up and landing with the T-hold on the motor does not hang lean on the idle it just works great from full tank to fumes...

cant wait to get my mits on the 1.06

The 3rd screw isn't a needle at all. In fact it is the seat for the low speed needle. Moving that out just moves it further from the tip of the low speed needle basically doing the same thing as opening the low speed needle more.

If it were truely a needle that Thunder Tiger wanted us to have access to and adjust then why did they hide it under the throttle linkage arm?

Thanks

But you are wrong about screwing out the idle screw...

moving the 3rd needle or "seat"
effects when the idle screw is fully out of the seat

it's not doing the same thing as moving the low end screw out

lets say that at 1/2 throttle the engine is lean and you move the low needle out now it will be too rich on the low.

it has to do with the amount of fuel needed at a certan carb opening
adjusting the 3rd needle or"seat" changes the %of fuel delivered at that carb opening without sacrificing low end relilability.

It's just a seat so how can moving that further from the needle effect the way it runs if the idle screw is already "fully out of the seat"?

I don't understand...

ok, i wil try to explain it the best i can .

if the 3rd needle is set at lets say 1.5 turns
and the low is one turn out from flush the needle will be exposed at
lets say 35-40% throttle the engine will be pulling a vacuum through the carb to take the fuel and air into the motor and you will be running the low end richer than required at this time to try to get the motor to run smoothly through its full range of power

now if you set the low needle to "flush" with the carb body
and the 3rd needle to 2 turns out your needle will be exposed at 45-50% throttle ( this is approximate and just for explaning purposes only) the engine is pulling less vacuum and requires more fuel at this rpm.

Remember the needle is tapered,

if someone can explain it better please do so!

the engine is set up from the factory to what appears to be ment to run on 10~15% nitro hence the seat set @1.5turns lower nitro will require leaner needles.

I see that you are running an evo/.53

if you want to try it, open the throttle all the way and check to see where your needle is set if you are running 30% set it at around 2 turns and run the low flush then tune high for your altitude.

it made all the difference in my motor..

I sent mine back to Ace Hobbies on the 3rd and they still haven't looked at it. I was on vacation this week so I thought it was a good time to send it in. I didn't know they would sit on it all week or I wouldn't have sent it in.

I have just flown my new redline for the first and second time today and i have to say i'm very impressed. I ran it on coolpower 30% with the hatori SB-50TT. It started and idled PERFECT AND LOW on the first start without touching the needles. The only thing i had to do to get it running cool was ritchen the main needle. I have run two tanks through it so far. I also like the hatori sab-50tt nice and quiet but the motor really likes it.

Mine ran GREAT for the first 2 gallons and then it started getting worse as it seemed to break in. I hope I get it fixed because it did show some excitement.

I guess we will see how she breaks in. I knew i was taking a risk wanting to try something different but he who is without risk is without gain. I hope your motor works out. I also hope i don't have to send mine in. I'm not a very good at waiting for costomer service.

tt53

burned 6 tanks thru mine today and 4 last weekend which were the first. I took everybody's advice and opened up the "3rd" needle before even firing it up!
Running great! and I expect it to continue this way.
