Zero Pitch Set Up Methods?

[SGsailing]

Having just set up a BeastX and Outrage FBless head on my Knight 600e I used the main blades together method to find zero pitch after levelling the swash. How do you all find zero pitch without a flybar?

Bought a Align 600 flybarless pitch tool.

Hey.

I use a Robart Jewelled pitch Guage which works well, only gripe is it only goes to +-10 on the pitch scale but it's easy to work it out over this.

It's the second one down here;

Midland Helicopters Ltd VarAccs_PitchPaddleGaug

Not cheap but easy to use.

I used a beast x bevel box on mine, super easy.

Bought a Align 600 flybarless pitch tool.

I done this too and now also brought one of those digital pitch gauges that Busterboy linked to in another thread.

I just double sided taped my iPhone with ihandy level to my pitch gauge. Calibrated the level to the heli.
Was really easy to set up, going to use it for my fly bar models as well :-)

Looks like these guages require the use of a spirit level to determine zero pitch.
I guess this is OK except that don't you need to make sure that the heli is on level ground?
What about those that have have the main mast angled slightly forward with respect to the skids?
Not seen one in the flesh so could be way off the mark with it though.

With the power on, and your transmitter set to zero pitch fold both blades to one side, 90 degrees from the blade grips, and see if they are level. When the blades line up you have zero pitch.

Hope this helps

Great guys just what I was looking for. I used the same method as Chris above but thought that any wear would thow this method off little.
I like the idea of a Beastie box bevel gauge.

Thanks Steve

A cheap way of finding zero, long screw driver through your blade grip bolt hole, and line it up with the main shaft....hey presto...zero

I do mine the Rob Turnbull way with an allen key through the blade grip bolt hole, same as the screwdriver method

Cheaper Still Inclinometer

Ditto for my 500. I'm not a fan of the digital levels, as I know my worktable (kitchen table) isn't level, so it would mean shimming things up every time to get the heli set level. Using the FBL pitch tool, it doesn't matter, and it's just the same as setting up a flybarred heli.

I'm with toetapper..
I remove my blades, put a long allen tool through the blade bolts and when it's dead inline with the mainshaft, there's your zero pitch...

I then get my spare flybar, any size will do, and use a big blob of bluetack to hold it in place on top of the head, and get it level using zero pitch on the pitch gauge after attaching the blades...

Now I set all my pitch ranges for the heli, with reference to the now level flybar....

You don't have to level the heli Brian, just set the heli on a bench then put the digi level on the same surface and reset it to 0. Don't move the heli or if you do return it to the same position and you are using the same reference.

Make sure that you check the blade grips in the same direction as the reference surface. We use inclinometers all the time for levelling machines and robots and all you need is a reference surface
