actually 2 stroke engines are more powerful than 4 stroke, but they are very (cough cough) smokey

this is always an area of confusion, in theory Gk you are right, 2 strokes are more powerful, higher rpm and firing on every stroke. problem is they are not very good on torque and from a scale model point of view they are noisy, smokey and usually have massive exhast systems to somehow try and hide. so four strokes are my preference, lower noise, more useable power with the higher torque and they sound great, especially 2 of them humming away together! as a result i only have 1 two stroke model now and dot plan to buy any more 2 strokes. when done my hurricane will have a 20cc laser 120 fourstroke up front, these are the best model engines you can get and i love em!
