Sync Pos

[airbtb33]

Pete:

I'm humming along setting up the controls for my Majestic Dash-8 300. I think you're already aware that axes 3 & 4 have to be used for the throttles and props. Is it possible to sync the position of just Prop pitch 3 & 4 without having the 1 or 2 axis assigned or calibrated? Every time I click on the Sync Pos button, a windows chime sounds and it doesn't appear to line up the controls when I go back into the cockpit.

I'm not sure if this makes a difference but the axes are on different quadrants. Also I changed the lower bound to -24000 in the .ini file to prevent the axis from cutting off the fuel (using the "reverser?" button for that... below the detent on a Saitek Pro Flight) but both axes have identical start and end points. And I have a center detent from -1280 to 1280.

Thanks in advance

Er, sorry, no, I don't know. Do you mean it ignores Throttle1 and Throttle2 controls, and also Propitch1 and Propitch2? Why on Earth does it do that?

No, it isn't designed that way.

No, that's irrelevant.

That's a strange way of doing it. Why not simply switch on the "no reverse zone" option in the calibration tab? That's what it's for.

I don't have the exact information in front of me, but from what I remember "engines 1 and 2" were running in the simulation in some way, but the user controls were mapped to 3 and 4.

From the Dash-8 forums I read:

FUEL OFF is a full FEATHER position of your CLs. Its -4096

The START/FEATHER is anything that is between -3850 and 0

If you switch on the "no reverse zone" option (0-16380), you basically get travel only between the min and max on the quadrant, losing the start/feather portion of the props. That's what it looked like to me anyway. By changing the .ini lower bound to -24000, that gives me an effective output of around -2800 to 16380 and allows me to set a detent around the min position at 0. If there's a more efficient/elegant way of doing this, I'm open to it.

Hmm. Sorry, I don't understand that.

Ah, so there are three zones, not the usual two. Hmmm.

If you switch on the "no reverse zone" option (0-16380), you basically get travel only between the min and max on the quadrant, losing the start/feather portion of the props.

But it's odd that 0 wouldn't give you Start/Feather, because that would be normal, and as you say " START/FEATHER is anything that is between -3850 and 0". it seems strange to exclude 0. Are you sure you calibrated the 0 poisition with enough range on the axis to be sure that 0 is always produced when you pull it back?

If there's a more efficient/elegant way of doing this, I'm open to it.

I can't think of anything different if 0 doesn't give you what you want. It just seems a little short-sighted in the aircraft design department.
