Eric, not on your list but I am building mine with a Brison 2.4. Most of the glow guys are finding the plane to be just a little on the tail heavy side with the OS's and even the Moki is a tad light in the nose. I saw the MVVS at the show and was very impressed, 'specially with the walbro carb. A little extra weight but the performance is a little better and it runs on 5% nitro which can only be a good thing. Can't wait to hear what you decide to do. My engine is here now I just hope the muffler gets here by the weekend so I can try it out. The plane is all together except for the actual engine install.
