Once you get bored with the mach 1, get the mach 2.

I have been flying one with a 46AX and building up from an 11 x 4 to an 11 x 6. It has flown in 17mph crosswinds and is a lot of fun (my second plane)

A more experienced pilot managed to get this to knife edge, fly well inverted, and hover.

Not bad for a $60 ARF!
