Hello everybody!

Yesterday I've received my Epsilon 120 from CAmodel. It's ARF, so I have to think about what engine to use. I'll use it for competing on Artistic Aerobatics and to start on F3A. I was thinking about three engine options:

1.- Electric powered. What e-setup (engine, speed controller, what and how many batteries, prop...) do you recomend me?
2.- OS 140RX or OS 160FX: I really don't know which one would be better and why. One problem about glow engines is that I think it's near impossible to install a large pipe, because the epsilon is wood built and the wing (is a one piece wing) is installed on the inferior of the fuselage (like the widebody or epsilon 60), so I think I'll have to install a stock muffler?

I need your advices

Thank in advance
