hey i am new to the conversion and rc. but have been reading and doing a lot or searching and i think it is time to put use back in my 2 old weed whackers. i have weed eater GTI 15T i have no clue about it other than it looks like a ryobi witht the carb and exhaust in the back...i also have an Echo Gt-2000

my question is this
does anyone know anythin about the Gt 15t size what it is and can it be converted

and does anybody know anything about the Echo..i think it is a 22cc but i don't know where to find parts to convert it

so do i have an engine that is worth the trouble of converting to rc


any help is appreciated
thanks
ben
