Last night I installed the fixed servo tray in my Caliber 30 and changed the Swash from Nor to 120 Deg.

I have everything set up so that the helicopter responds correctly to the TX. My question is, how do I change my blade pitch/collective now??

1. For arguments sake, let’s say I need to increase the positive pitch for my main blades. Do I adjust the settings in SWAH from the current 70/70/70 to something like 80/80/80, or do I adjust the EPA (End Point Adjustment) of the servos??

2. What does the 70/70/70 setting mean??

3. Also, do all three numbers in the SWAH setting have to stay the same? Or for whatever reason can you end up with something like 65/80/70??

Thanks for your help,
Rockohaulic

Yeah so don't touch the endpoint on those cyclic servos, if all three aren't the same then you will have different trim at different collective stages. If you need more collective throw(all three servos need to move further) Then you can increase the SWAH setting for channel 6. you can try this, turn on your radio gear, move to full collective, or full negative, and start changing this swah setting, you'll be albe to see all 3 servos moving. Changing that chanell 1 SWAH setting will affect the Roll cyclic throw, and the channel 2 will effect the Pitch(provided this is a hitec/futaba radio). I've been flying a CCPM heli for about 6 months and I am still learning about all the interactions. But I would really stay away from things like subtrims and endpoints.

If you need MORE OVERALL travel in pitch, then increase the PITCH mix value in the swash menu.

If you need to increase or decrease OVERALL aileron cyclic, then increase or decrease the aileron mix number.

If you need to increase or decrease OVERALL elevator cyclic, then increase or decrease the elevator mix number.

Set the actual pitch-to-stick deflection using the pitch curve menu.

The numbers DON'T have to be the same. In the end make sure that as you increase or decrease pitch that the swashplate remains level, and doesn't tilt.

Don't mess with the individual endpoint adjustments for the three channels.

OK Thanks guys.

I won't touch the endpoints.

However, I had to adjust the subtrim settings to get the three servo arms to align correctly with the sticks in the center position. That's OK isn't it??

yeah, should be fine, I just try to stay away from subtrims on everything as a rule, not sure why, but it always seems really strange in my head to use them.

Before resorting to subtrims -- did you try putting the arms on in different positions? The spline on the output shaft is designed so that when the TX channel is at neutral, there is ONE particular way to put the arm/wheel on the servo so that a line connecting the center of the shaft with the holes in the outer part of the arm/wheel is perpendicular to the sides of the servo.

You simply lift off the arm/wheel, turn it a bit, put it back on. For the two- or four-armed outputs, just try the arm on each of the four obvious ways. One way will usually give you the right orientation.
