I would rather use gas instead of glow. A glow engine that size will for sure suck some liquids down. I think gas would be much more cheaper. Not sure what the pros and cons are for gas to nitro on 120 size.

Does a gas on a 120 size have enough power to pull vertical or nitro? see not to sure which one would be more suitable for this. Looking for a power-plant that will pull the planes weight and then have enough power to gain altitude. Looking for something that will be more than enough power for this type of plane but not ridiculous and over weight. I don't want to have just barely enough to get a hover. Want to make sure I can have total control (or enough power) at all times pulling gaining or descending from vertical.

If that makes any sense. Kind of lost myself there.
