Right now I am wrapping up the assembly of this combination. The Meridian 10cc is a nice built ARF. (my 1st Hanger Nine Plane). Everything on the build seems strait forward. I am only using one battery which is a 6.6v Life 2200ma Lipo. to power both the ignition and servos. In balancing it, it is comming out slightly tail heavy. I will need about 4 oz.of lead in the nose to balance at 90mm. I also have the Great Planes 3.5'' Aluminum Spinner. Hopping to maiden this bird this weekend. If I were to do it over I think I might of went with the Sig 4* 60 and a 15cc engine.

The only thing I would change with your build and it might help with the balancing, is that I would opt for two batteries. One for ignition and one for receiver and servos. I just firmly believe that with a gas model, you should be using two batteries. But, only again, that is my personal opinion.
