    Idle needle factory setting?

    It's very known that to reset the High Speed Needle to factory settings on most RC 2-stroke engines is 1 and one half turns out from closed, and to reset the Low Speed Needle, 1 and one quarter turns out from closed. Question: How many turns out from closed should the big idle needle be?

    Normal to have to change tuning after pipe?

    I had the stock muffler on my 26cc 001 and tuned it a little rich as it's still in break-in mode. I ran it around then changed to the tuned pipe (love the sound difference!!). Anyway, I had to really lean it out to get it to run after installing the pipe. Its still about 1 1/16 out so I think...

    Engine tuning in colder temps

    As we near the end of October, I was wandering what people do to run their trucks in the colder temps and possibly snow? Do you still tune by temperature? Any tips would be greatly appreciated. Thanks.

    Tuning engine with Jetpro pipe

    HELP!! Tuning engine with Jetpro pipe I put a Jetpro pipe on my stock (23cc) DBXL engine. From a stop I go to full throttle and it takes time to come on the pipe. In that time if I let off the throttle it keeps accelerating. I can only get it to stop by hitting full break.

    After our visit to Largescalerc in Monon, IN, I deduced that I desperately need to figure out a better tune for the loose hard pack of their track. I am running the orange springs, and stock tires. I had next to no steering on power, so I know I'm going to need to do some diff work also. Any...
