I remember when you could buy a rvosd for $299 but now it's over $525 pluse the tx that's a total of $650 ? holy moly whats it got under the hood now? I had gen 1 2 3 5 and 6 and they all broke for one reason or an other. I would rather stay with my vector or pixhawk and FPVblue system. never had one break yet. at least the gs tracker is still only $150 they must have lost a lot of biz.
