I'm shocked!
I thought the horizontal speed was around 50mph!
As a comparison, the max UK motorway speed is 70mph.
I've done a mod on the sander antenna and added a ground plane. It's only a length (the same as the antenna) of mig wire which os soldered to the outer casing on the antenna. The difference is superb..... I could only get to 300ft without the RTH on the Vector kicking in but now, the sky's the limit (pun intended).
