Well I tell you some thing The plane you are talking about is nothing like you are flying . You have more power and a lot faster control than an electric. As for the servos, the 46 is about the standard size for all radios and will work on planes up to 120 size. Your mimiture survos are for small plane's that do not weight much, and have what they call low wing loading.You are looking at a whole different type airplane, and a big let down.
Just to let you no what can happen my 30 year old P51 lasted 3 minutes[:@]
