any 2.4 transmitter guru's about ?!! please help

[shaun m]

Hi , I've had a futaba 3gr for about 18months ( bought 2nd hand on here ) also had 2x frsky receiver and they've always ran faultless ..

Was at torch yesturday , when a few of us has issues , mine started as i put the car down trackside , got up on the rostrum , and realised my car was'nt there , got off the rostrum and realised my car was upsidedown about 10ft away from where i placed it !! , assuming it was the receiver i swapped it out of my other car .

Attempted to go out for a practice , switched it on and it started steering and revving , turned it back off and thought wtf , by then it had come apparent that someone elses car had picked up a signal and gone off track ( also on a futaba 3gr 2.4 , who has had a simular problem at another track ) we then realised that both our transmitters would interfere with each others cars , soo we waited for each other to have a practice etc ..

all was good untill round one , switched it on just before the start of my heat , and it crawled onto the track , my mate was using a futaba 3vs ( was in the heat before )and has also had the same issue before was still racing at that point , soo i went off and swapped the receiver again !! got 3 laps in and it was fine..

i did accidently swith my transmitter on only to set my end points etc , and it seemed to have interfered with the other car on his practice lap ( sorry james , causing his car to go off the jump ) mine was fine for the rest of the meeting , altho my mate who was in the heat before , i made sure he had finished and turned off , before i switched mine on etc )

As i said mine was fine for the rest of the meeting and afterwards , using both "suspected " receivers and both cars were fine ..

but the other car , was doing well in his a-final , with a minute to go , and his car went off again , , but both mine and my mate's transmitter were both switch off ..

As i said i've had mine for 18 months , and its been faultless , gets used twice a week , done the EOS national at torch last year , with 100+ entries on both days , done a indoor series with again over 100 entries and mine was fine ..

Sorry for the long story , but has anyone else had any issues before .. cheers shaun
