If you want to get into gas and wanted a 30cc plane there are a lot of planes that will 3D with these engines just take a look at the gas engine forum. The 2 that come to mind are the Syssa and the DLE 30, Dle is comming out with a new rear carb version of thier 30 very soon wait for the rear carb version. Valley View RC has several planes in this size that would be great. Extream Flight is or will be comming out with an extra in the 30cc size very sonn if they have not already.

The 30cc engines out now have no problems swinging 18 to 19 inch props.

Gas is the Only way to go!!! Save money and fuel.
