Auldey Toys Sky Rover Exploiter

Howdy
I have a skyrover Exploiter S I got from Wally world. The controller has YW858050-5 on it. The main board inside has YW858060 TX on it with a small RF board on it with BM 1024H V1.1 marked on it. The chip is potted over with a small metal can glued to top of it that has 2 wires on it maybe cap or xtal. I took both controller and heli apart and there are no numbers on the chips. I contacted Auldey but they said that info wasn't available. Can anyone tell me what protocol they use?
Thanks
John
