i cant give you an advice, don't fly over your head, or if you do that, change position of your antenna in the control. But best thing is, to keep it in front of you, than you will never loose control, unless something else will happen.

Ron:
You are absolutely right about not flying overhead.
It can be confusing with a fixed wing, but with a heli you tend to lose all orientation as well as with 2.4GHz losing the signal.  :(

I'm going to try keeping the Tx antenna horizontal across the front of the Tx and keep facing the model.

Happy Days:
Ron,
Didn’t you say, somewhere on this forum, that your 2.4 equipment was a modular system and that you could operate on 35Mhz?

You shouldn’t have any LoS problems on that QRG.

I was thinking last night. :?:  (I do that sometimes you know,………..Think :roll: )
If you are losing signal with your 2.4 gear, the rx will probably take a second or two to re-boot at Acquisition of Signal, which would only add to the “out -of-controlness” of the model for those brief moments.

Dilemma isn’t it. :!:  Loss of signal? or Lack of Pilot skill?
 
They do say “A bad workman always blames his tools" :lol:. (I'm always going that. It's so much easier than admitting I'm wrong!)

Ron:
Yes you are right Keith (well sometimes anyway  :twisted: )
I've got a 35MHz Cockpit SX with a 'stick on' (literally) 2.4 module that plugs into the 'tutor' and charging socket, so you can switch between the two.
There is a snag though (there would be...)
The ESCs say they are not suitable for operation with 35MHz RXs.
You tell me???
Does that mean they chuck out so much interference at 35MHz?
I would have thought EMC regulations would have said you don't get EC mark approval if that was the case.
Maybe the ESCs haven't got EC approval, though they have got the EC mark on them. Not that that's anything to go by.

And Rx re-booting. Good point.
And in this case the gyro/controller thingy probably has to 'acquire' the Rx signal input too.

Happy Days:
Yea’ It could be that the ESC throws out interference, particularly if it has a ‘switching’ BEC. (As distinct from a ‘linear’ BEC, which is basically a Voltage Regulator)
As far as I’m aware the ESC doesn’t radiate the interference so much as allowing it to run up the positive wire straight into the rx!

This can be overcome by cutting the positive wire from the ESC and using a separate battery to operate the rx and servos………but that adds more weight. (Or, more complexly, with tunes circuits and ferrite rings. )

OH BOTTOM! :!:
Don’t know what to suggest for the best Ron. :?:

What ever you decide upon you could always test the system with the model secured to the ground. Can’t get damaged then!
