Hi there,

In my opinion a good 2stroke is good enough. The 4strokes though are better performing in the torque factor. To make it easier forthe beginers Torque is present in all the aspect of rpm when you use the 4stroke. That is giving you better handling characteristics for your plane when you land and definately when you take off. Now in the 2stroke the torque is sudden and there is a lack of torque in low rpm This may give headaches for the beginner.... the hit of the sudden torque in high rpm is many times fatal for your plane esspecially if you try to abort lets say a landing. Also the 4strokes can take bigger propellers. It's for you to decide. Anyhow both engines keep modellers fly....
Cheers
