Yes I know exactly what a 4* is, over the years had 5 ,have one now that I play with at times,4* 120 w/G38.The question was asked by a person that has very few flights on his LT40,with that amount of training a tail heavy model can and is usually a disaster,as an instructor of many years I've seen a lot of wreaks on tailheavy planes.If you are happy with your set up then have fun flying it,but from your comments it sounded like you had problems,sorry for reading wrong.
