Thanks, your engine really sings. I'm thinking to get one over the winter.

@rcst67eve

I can help you on a cilinder if you have all the parts , otherwise get the evo rcmk cilinder......

[johandraijer1981]

Chrome is ok , this cilinder runs for more then a year now , also had some dyno tests with it and still is in verry good shape , engine get new bearings and new piston now.

Very nice sigma, i have one but its not that fast... Can you tell me what kind of prop do you use and if you use a strut or a stinger? What is your point of balance? Many thanks in advance

[johandraijer1981]

@varadero21

It has a strut , prop is 7016/2 and psr nb01 , point of balance is at 460mm from transom , this is without trimtabs and the fuelbag is between engine and rcbox.

Thanks for the info. I will try this setup ( i am using 6717/3 and a stringer. My CG is at 43 and i am using a stinger with ttim tabs) Although i believe that your RCMK is blast and can spin anykind of prop.

@varadero21

That is true , i had other engines in it and also the rcmk in stock form , it was no fun :-).....

Thanks, I have a older cylinder from a few years back. Tried on a Zen26, didn't work as good as the Zen. Yes, the s254 evo is what I order. There is some guy here saying the seals on front bearing need to be "ca" to stop them from poping out.

well tuned engine. How do they hold up? I heard someone had problem of chrome in cylinder.
