I have an evo .45 and its GREAT

Starts easily and runs all day ! I bet the .52 will be a great engine. More power for a negligable amount of weight.
What is the difference between the .45 and the .46 ?????

the 45 comes with the flywheel it's called the evo training system they put it on the alpha forty and the arrow RTF not sure if the p-51 PTS uses it too or not
