Thank you to everyone who has replied... much appreciated
Last night i removed the module.. opened it up to check the aerial wire was ok.. seemed to be... cleaned the pins up on the TX and bent them slightly..(tried it in the TX felt abit tighter fit..) On the module i put small bits of electrical tape on each corner x 2 layers. I fitted the module back in and theres no movement now.. so will see how i get on!
Ive got a couple of voltage regulators / capacitors coming aswell so will plug into the receiver to see if that helps also.. Thanks to Darren at DMS for this..
I'll will update you all when i have tried it all out..
Cheers
Nick
