RE: hydro problems
Ok then I have fitted hydros to a FG MT. You do not need to cut the roll cage just shorten the post the master cylinder sits on so it clears the middle bar and drill the hole on the bottom of the post once you cut it to extend the hole and then re tap the thread. You can use your standard radio tray and where the receiver box is remove that and put in the third servo needed to control the master cylinder. The only down side to using your standard radio tray is that you then have to mount the receiver box in places it doesn't really belong. The proper solution is to get FG Radio Tray Part No 6117. This has the spot for the third servo but it also has mounting holes for the reciever box as well which places it at the back of the radio tray in the middle above the spot for the battery.
