2.4GHz for video and RC - not a good idea?

I have the 1.2ghz Fox-700 tx/rx which ranges from 1010mhz (ch1) to 1280mhz (ch15)
I assumed that on 1010mhz I wouldn't get glithing with my Futaba FASST 2.4 but I was wrong

1.2ghz video Glitching 2.4ghz RC

I should have known as I'd already heard about the second harmonics problems between 1.2 and 2.4 and I'd even seen this following video

Servo jittering due to RF Interferences

But of course I thought I was special

However, having switched the video tx/rx to ch15 (1280mhz) I don't get glitching


These items have not been used for FPV or anything other than testing

In the long run you'd be better to get a 35mhz radio that can take the OpenLRS module at a later date and use 2.4ghz/5.8ghz for your video, although 2.4 is less prone to obstructions (trees etc) the legal power output is less than half that of the 5.8

If you're wanting to strictly adhere to UK laws then the plane has to be within a range that allows your spotter to determine it's orientation and proximity to other aircraft and give you instructions accordingly, so in theory 5.8 with good antenna are more than you will ever need anyway and adding to that that 2.4 FASST will get you that far with ease then you could just stick with 2.4/5.8 which is what I intend to do

All that long range stuff has been done to death on video, it's got to be the most boring thing ever to sit there with your goggles on for 6 hours watching the clouds crawl past
