or do i zero it somewhere else on the helicopter!

Many thanks in advance

I zero mine on the table.

Then put your pitch gauge on the blades at 0, whilst putting the inclinometer on the top.

This will give you the degrees of pitch.

You need to calibrate it in the direction that you are going to use it. If you are checking say pitch and you have the blades along the tail boom then you have to zero it at 90 degrees to the tailboom, Ie in the same plane that you have the blades.

I zero mine on the table.

Me too.

Me too.

The only problem with this is that if the heli is not sitting parallel with said table in the direction you wish to check your bevel box inclinometer is as accurate as a bowl of blancmange.

In order to work properly the reference surface has to be parallel to the one you are checking
