I had a switch, too bad they never went to the helios module. I like mine a lot. like I said one bad rx of the 3 first runs. and they replaced it. but then the rx came out way before the module. so I first tried the recievers with existing 75 module on the m8 and when the module came out, went straight to it and had no problems. a bud had a problem with the module glitching and had it replaced. he was worst them me he could not wait the week for the replacement so he purchase a second module and sold the first when it came back.
