The Epic .18 is 1.8hp @ 39,000rpm wich puts out as much as the stock ofna .21 and .26.

I ordered this engine 2 days ago after i saw that some else has it on the forum.

And i bought the O.S .15 from my friend yesterday for 30 dollors and ordered a new piston and sleave for the .15 and see which one i like then sell the one i dont like on ebay.
