Have used a mini fmv as a back up leg mount transmitter on my gos for the past six seasons flown 5 days a week.
Over this time it has worked faultlessly despite taking a bit of a pounding as leg mount transmitters undoubtedly do.
Recommended and great service from the FE team to boot.
The mini fmv is one of the best transmitters I have ever used,I used one as a back up,leg mounted and the tx 20 on the tail on a falcon and only had to track the fmv.
Very good in hilly country and the batteries way out last the stated life in the makers info.
I got a good signal at four miles with the antenna removed !!!!
I now use two fmv's on any falcons I fly.
They really are great.
