Hi Flymyplane,

I'm surprised that DP told you that it was alright to run the G45. They've obviously changed their tune about gas engines, and it's about time. I think the G45 is a bit heavy, but definitely will work fine. I remember someone that put a G62 in theirs and it flew ok...but that definitely wouldn't be my first choice.

By all means put all your goodies in the rear. You're most likely to have the reverse problem with the G45 and need some extra tail weight. I'm guessing you'll need your receiver batteries in the rear of the of the cockpit area to balance correctly.

As far as the prop size, 18" sounds a bit small for that motor. I'm not an expert on the G45, but I'd guess a 20X8 or 10 would be more like it. Don't be afraid of the large prop sizes for this plane, they will work better overall. My favorite on my Taurus TS-42 ended up being a Zinger Pro 22X8 and I tried a bunch of props on it from 20X10 to 22X10 (Moki, Zinger, Menz Ultra and S).
