HeySig,

I hear ya. I had a few choices for the power plant. I bought this engine last year thinking "Somethin Extra" I have decided to take it easy and slowly grow into a SE. I believe if built correct the 4 Star 40 is a good match with the 46FX. I am looking into a Thunder Tiger 42 or 46. Hell there is a guy at our field that flies a ST 51 in his trainer. We also have a few folks who have dropped FS 52s in their trainers. If I purchase another 40 size engine before I mount this one, I will swap and save the 46 FX for the SIG SE I just bought.

Pale,

I have some photos for you.

First is the bottom of the wing with servo in wings

Hope it helps you!!
