no need for a plane... just get a long travel suspension

in addition to what craig said about the SLR truck...

as i recall it has
>14" of front wheel travel... stock is 7.5 i believe...

the rear suspension is literaly frightening...
with out getting into details i'll just say it is not even remotely stock... but from the photos you get a good clue of the difference by the fact that the rear wheels touch down first... even with the long travel front...

it has Bilstien Resevior shocks all around, hydraulic bump stops... etc. etc. etc.

you can fly in a X... but to do it safely and with out damage requires a few changes
