Just maidened my 3rd. Giggles-n-grins. The designer is still flying his prototype (purple & white) used for pics on the box cover.

No need to bash the kit to have a blast with it. But you can definitely change things should you be driven. An OS 46 AX with a 12.25x3.75 APC prop does nicely at 5800'.

Like Thatsakitbuilt said - read and re-read the instructions before cutting or gluing ...
