What clone are you talking about Tony??IMO, I would NOT put a clone FBL system on a helicopter such as the Protos. Way too much money to trust to something that was ripped off from a good gyro. I would save your pennies and see what you can get. 3GX, Ikon or AR7200BX are all great choices. I fly the first and third and they are rock solid. I"m about to put the 3GX on my 600 with 4.0 just to see if it will work as it's supposed to so that I can run a Gov. You can find a 3GX all over the place for $75.
