My best friend bought the frontier 40 and is using it to learn to fly so far so good...it is a decent plane. Has about half inch more length on each wing than most trainers except the LT 40. Only thing he had to do was with his 46fx he put in it he had to notch quite a bit out of the nose for the high end mixture valve to fit ...other than that i thought his plane is quite decent for a trainer. His was a bit easier to put together than my Kyosho 40. I had more little quarks i had to deal with....no big things just annoying.

So...Yes..seen it ..watched it be built...saw it fly...good trainer!!!
