Yeah, I don't think It would fly well with a Saito. But, I bet a Big Gulp that that plane will be nowhere near 11.5 lbs with a SPE 40. You should buy a lottery ticket if you can get it under 15.

That Edge has similar dimensions as the old H9 Edge...and also has a very similar profile. The H9 was 12.75 lbs with an OS 160. It will probably fly as good.
