Good day all

i need some help pleese. i bought an accoms 2.4 about 6 months ago after my spektrum DX2 failed Continuously.

i also bought 2 extra recievers for all my race cars.
in practice a week or so ago i found that my superstock car was loosing signal when it was at the furtherest point on the track,yesterday at the race meeting i only ran 2 classes and took the third reciever from my third car with to the race as a backup.in morning testing the above happend to both cars and i then did a re-bind on both cars and replaced the batteries in the radio.
After doing the re-bind i had no more issues with the super stock car but my mod car ran away in the second qualifier taking out the leader and breaking both cars.

Can anyone help in this regard?
