First time I've done some good FPV with my tri, and I love it, fly perfectly, for about 15min. May be some adjustment on the yaw, and I have to improve camera stability!
At -20c it's cold, we have to pilot inside the car. But craft are ok with a little while in the cold, 1-2 min. I actually had more trouble with Gopro!!!
Weird thing is that it seem that 1.2Ghz was jammed... Fortunatly, I had a 900Mhz to test... and it was perfect!!!
