iFlight Nazgul5 V2 + Succex VTX - antenna advice
« on: November 29, 2020, 03:24:40 PM »

Just managed to avoid obliterating a brand new iFlight quad.  :o

Set up in BetaFLight, did some LOS practice first and it's beautifully dialled in (and toned down to beginner's rates!)

Flew FPV for the first time this AM, went up to 50ft, out to about 150ft was nice and crisp, banked right and got flicker first then black screen signal loss. I then dropped the power and then killed it when my spotting buddy shouted yikes at about 10ft up!

I'm using the Makerfire cheapy FPV googles with 14db patch antenna and the other one is a mushroom style. It's obviously not the best but I've used it successfully on fixed wing with an AKK VTX out to 400m+ (I also stepped up through the power on the Succex. but this seemed to make little difference and was same result on second flight.)

So - are the control RX and VTX antenna too close together? I've seen loads of vids with this quad being flown at fairly significant range on stock set up so I'm a bit hmm..

All recommendations re alternate antenna or other options for improvement gratefully received!

Not that I know much but I had a similar problem a few years ago. My goggles were on a near frequency but not the same as the VTX. Up close all was fine but got out to around 50ft and the signal dropped off a cliff.
Check that they are on the same frequency.
Try walking out away from the quad, with the quad on the ground and see if the same happens.

Is the VTX power level adjustable? Maybe it's on 10mw or something instead of it's full capability.
