Hi, I´m a new STS .28 engine owner from Spain. My english is not very good, but i want to try.

I´ve got a XTM Mammoth with a XTM .24,7 engine and i want to ask you some questions.

I don´t know : How many Hp has this engine ? what about the RPM ?

I have recently purchased the .28 STS engine and i want to break it as soon as i can. what % nitro gas for break in ?Can i use my XTM mammoth pipe for the engine?. What pipes do you use on the STS28 ?

there are too much questions but i hope you help me.

Thanks you for all.
