a 320 degree novarossi sounds like a bigger problem than a cooling head. more like poor tuning or an airleak in the engine or carb...

Also, does anyone run a ko 2143 servo in their car? It rubs the rpm ball cups slightly and the servo can't be moved back.

Any help appreciated.

Yeah to a certain degree I guess I can but not too much to limit the strength. What about the steering throw, it just seems very small, especially if toy get stuck and need to make a tight turn quick.

Default 320 degree Novarossi....

I made sure the carb setting was correct I even had a few other people check it as well. The problem with the S5 lies in the head design. The head has 2 less fins than a regular Novarossi head. If I had not changed the carb settings and replaced the head with the CNH one then the OEM Nova head is the culprit, not a leaky carb or engine, and I doubt it was in the tuning. This is my fourth engine to tune, and at least 7 or 8 engines total that I have tuned for others as well ranging from a .12 to a .24 engine. I know the difference between an engine in tune and an engine that is poorly tuned so I doubt that was it. I am happy that the head swap did work especially after I spent baucoup $$ on the S5 motor. I need input frpm you guys on my next question. I want to purchase a legal motor. I have narrowed down the choices to 3. A .12 Sirio, a .12 Rossi Pixi Black, or a Novarossi engine. I am not too particular about claimed HP or what not since I will end up modifying these engines anyways. I will order a couple of sleeves,a piston,a rod and a crankshaft as well so I can experiment to see which one will give me the best result. The mods are going to be kept to a minimum so not to sacrifice reliability and fuel consumption. Which of the three choices do you guys think is the best to modify?

Default steering throw

I have found on my NTC3 that I needed to move the steering servo arm to a steeper angle than they show in the manual. Try removing your servo arm and moving it one more tooth to the inside. Shorten up your steering link to correct your angles and you should have full throw, lock to lock, without hitting anything. I have also always used stock ball cups up front, they work best because of the tight spacing around the steering rack, the bigger ball cups (RPM,ect.) always needed to be shaved somewhere. My ball cup on the servo arm has always rubbed on the servo, I think the only fix is to shim the arm slightly away from the servo, that fixed mine last season. This year I'm not going to worry about it, unless it's hanging-up it's not a big deal.

simonfdr,
Thanks, glad to be of help, need to keep all these NTC3's competetive. I just picked up my 3PK last night, simply awesome radio. I also tried the S9550 servo in the throttle position mounted below the deck, man does it look cool, and if functions perfectly. I'll post some pictures tonight. Good luck today!

Default S9550

Here are the photos of the S9550 in the throttle servo position. They don't really do it justice, but you can get a general idea of how low it is. I don't take credit for this idea, I saw it here, or on another board, but it does work.
