I havent tried a 14x6 however I have tried a 13x7 as I wanted to see what it would be like if I let the OS really rev as the quoted max HP is at 15000 rpm which is where the 13x7 revved it was well loud but hey just 1 test!

It did pull well but it seemed to run out of puff low down where you really need the power ... when will engine manufacturers ever publish torque curves so we can prop to how we want the plane to feel

To be honest the best combination which I curenlty have on my Seagull Harrier is the Blue OS hatori pipe set long with a 15x6 as this hits the tourque curve smack on. Its pulling about 10k and pulls the harrier (8lbs 6ozs dry) out of the hover ... not like a rocket but with enough authority to give you confidence.

I must say the YS is the only engine in this class that has the right power in the right place at the right time .... it simply can not be surpassed (excuse the pun)

Good luck with the evo 100 I have been intregued by this engine but scared by the sc / asp type of carb. Please let us a know how you get on with it

How are the other pilots out there getting on with there Epsilons
