Wheels, anyone drive FPV much here?

Recently got a DeeRC H16E as a newb ground starter and it's a hoot. Next step was getting a better controller: Radiolink RC6GS, like it much more than the came with version.

FPVing with analog to start (TBS Unify Pro32 1W) and a Toothless 2 or other cam from the parts bin is the plan.

Discovered that I can run Crossfire on the Radiolink with a nano rx 6ch pwm adapter. Cool beans, planned now too...

So, anyone run anything similar? Tips?

the cam on the back of the car dows give a good view without headtracking.
a antenna as faraway aa possible from th car would be benefical.
its fun :-) happy drive :-)
