B25-Engines?
Ok, I have posted this a couple of times and haven't had any responses so I will tryi one last time. I am building the Wing MFG B25, I want use gas power for this critter but I am having a hard time settling on something. I would like a bit of input and ideas from some people that may have experience with this aircraft and/or engines. it says its to use 70-90 Four stroke glow so my first thought was one of the those 15GX gas engines from Evolution but I am not liking the lack of info or reviews on it. The few reviews I could find about half or better didn't seem real positive. So, I thought maybe DLE 20's since they are tried and true but wonder if those are TOO big for this aircraft. I am not convinced on the reliability of glow power on a twin however, I am open to suggestions.
Thoughts Please!!

OS 90 FS = 650 grams needing 12 oz fuel (~300 grams + tank) for ten minutes full power.
vs
DLE 20 = 900 grams needing 8 oz fuel (~200 grams + tank) for ten minutes full power.
total weight difference only a few ounces but butt loads more power with the DLE 20cc.
I'm not a fan of the smaller engines that don't have caged roller bearing on the connecting rod ends.
