I looked through all of the entries in this topic and didn't find where anyone asked this specific question.

I am pretty sure I know the answer and will continue on my work to build a suitable mounting plate.

Can the gyro be mounted ahead of the main shaft?

My helicopter will eventually be installed in a fuselage and if it is mounted in the normal location behind the main shaft I will never be able to get at it to hook it up to the computer for making any adjustments without doing an awful lot of work. But I have a nice space ahead of the main shaft and directly over top of the servos to place it.

This is a 600ESP based machine so the elevator/anti-rotation arm is in front of the shaft as well and the mount will be just a bit in front of that. It will be flat and on the center line of the mechanics and right angle to the main shaft. I suspect that is all okay. It will be closer to the main shaft than the standard location but still 2 and a half or three inches away.

As long as you place the Spirit perpendicular to all 3 axes of the heli any place should be fine

Indeed, you can put the unit anywhere. Mounting place must be just rigid, shouldn't flex in any way and should be perpendicular to all 3 axes.

To solve your issue, you can use cable extension connected to the SYS position, so you can configure the unit easily even with fuselage.

Thanks for the answers. That is what I thought but just wanted to be clear.

I have most of the initial setup done now but want to get the wiring tidied up next before getting it all done.

I have made up a small plate that sites right over the front two servos and is nice and solid between the frame plates. Should be good.

Pardon the messy, and incomplete, wiring.

I really wished the plugs could have been at the end having them on top creates these wire loops that makes this hard to mount in a few places
