Hi

I have an evolution 40 engine came with an alpha 40 RTF has 6 gallson throught it,

What is the max rpm that this engien shoudl turn im getting 14 400 on a 10x6 apc is this too much?

I think this is too much because this is a cheap 40 sized engien and i have a feeling it will damage the piston/sleeve

EDIT: Im also ahve idle issues it wont die once the engein is warm it will idle at 600-800 rpm for about a minute and i ahve no clue as to where the airleak is (yes i ahve checked my linakages and ahve even gon so far as put my fingure over the carb and that didnt work the oring/gasket are still intact)
