cougar question
hey guys i have a few questions? well let me start of by saying this. i bought a sig cougar of a guy at my flying field. this thing is awesome flys way nice and i was wondering what i could put on this to get this thing going seriously fast. everyone at my field flys fast and in circles and im into 3-d and speed and i want to make this thing zoom. what can i do? right now i have a old supertiger 45 on it not the new versions and i have a performance specialties muffler on it. most say go with a .60 size engine. but i think it would be to much and other say theres not much u can do. oh i also have a 9x7 prop i think i cant see cause the nose cone on my plane covers the size witing but its small and has tons of pitch. id apreciate it if u people could lend me some advice.
