oh yeah and there is a good chance you will need to replace those servos, receiver and transmitter.. sorry I know i said you wouldnt
but like i said before i had no idea what plane you had.(and i still have not properly checked it out). that was realy bad on my part not checking first sorry i'm in a rush here.

if you're plane uses three wire servos, and at least a regular style 3 channel receiver that accepts an ESC you're blessed! if not yup you'll need to change out stuff sorry here are some suggestions

these come with receivers and servos you'll need to pick your channel for them though
join a club or get an experienced flyer to help you with that.

check the forum for better suggestions I just did this quickly just so you get an idea of the cost involved! this is by no means
a guide.... just for ball parks ok?
