walkera 4#3b FP wont bind
 

i got this heli a few days ago and put 8 flights on it , i also have the helimax and wanted to compare them both . the walkera is a good deal since you get 2 batteies and for 99.00 its a steal. well back to my problem , in flight the heli beeped and started flashing slowly so i figured it needed a recharge . pluged the second battery in nothing it wont bind. figured the tx was bad so i tried binding the walkera tx to the helimax , no problem binded right up. tried binding the helimax tx to the walkera heli and nothing, but it does bind to the helimax heli.
has anyone else have had problems with the walkera recievers not binding after a few flights .
