Pitch settings

[jonny1bar]

Hi,
Does anyone know the ideal degrees for the pitch in idle up 2, I fly with a futaba 10c with spectrum module.

It seems to bog quite a bit with 100% pitch, i now use 90% a lot better.

Just wanted to check the pitch against a spectrum radio

Thanks

i use 11 degs + and - , flies well at that

Thanks Mike, Good to know.

Guys what are you using to check the pitch?
I got my rc logger but looks too heavy to use on the tiny blades. Haven't tried though!

I did a quick cad drawing to work out the blade deflection.

Yep thanks about that...... Il get on it right now

i just used a 60mm by 60mm bit of paper, cut into a rough cross shape, draw a 90 degree cross onto it, then use the kids protractor, mark off the pitch angles you want to use, ( i use 11 degs ) right through the middle, then use a sharp knife and cut a slot along the angled line you have drawn slightly longer slot than the width of a blade.

its dead easy from here on, make sure your throttle hold pitch curve is the same as the one you want to measure, and fire up the heli, apply throttle hold switch, fold both blades the same way and put your stick in middle pitch position, if both blades are dead level with each other, then you have 0 pitch at mid stick, to adjust it dead on use pitch subtrim + or - a bit, then straighten your blades out and apply full collective, slide the cut over the blade, the vertical line should align with the mast / main shaft if the line is to the left of the main shaft you have too much pitch, and if its to the right there not enough, adjust by either pitch curve if too much or ATV if not enough

simples ;-)

finding 0 pitch on the 130x is much easier than that and requires no pitch guage! Hit throttle hold, Hit idle up, push throttle to exactly mid stick. On the head either side, next to the blade grips, is a line embossed on to the plastic. Also, on each blade grip is an identical mark. These marks on both sides, should line up perfectly, if they don't the links need adjusting. 11 degrees can be set up on the settings within the specific model on your transmitter.

yeah the marks are there buts it not to accurate for us oldies with not so good close up vision, swing both blades the same way is easier to see



All you guys feel free to print this off and stick it on card or better, make a slot at 11 degrees pos and another at neg 11, cut the top and bottom so that you can still see the vertical line, this is what you align with the mainshaft, cut another if you want at 7 for the cyclic, or cut what ever you want your pitch or cyclic max travels to be, on FBL models.

if you have a flybar model just cut the one slot at zero degree line, then slide it over the mainblade then as you increase or decrease pitch it can be aligned with the flybar, and read off the scale

cheap and simples

Freebie attached to post above, for your free pitch gauge, just scale it down for a NCPx or scale up for a 700, print it off and away you go
