One of the fellows at my home club has one with an Evolution 1.00 in it - I've had a fly of it and it flies great.

He used all of the stock standard equipment in it (built it in 2 nights then maidened it the following day) (He's the original miser when it comes to spending money on additional equipment) It's never given him an ounce of trouble. It was all set up as per the instructions (CofG in the middle of the recommended settings and throws as per those recommended in the manual)

Based on the Evo 1.00 working well - I'd go for the Saito 1.25 if there's a choice but the 1.00 will probably work fine also (I'm a power junkie - I tend to go for maximum engine size).

Good luck with yours

BTW - I hope you didn't have the 1.25 in your Aeroworks Edge!!
