How Do I Increase the Throw on My DX6I

[Gregg28]

I want to increase the throw on my DX6i. Even at full travel, I do not get as much throw out of the servos as I do on my other radios (including a DX6). In the past I have reduced throw by soldering a pot or resistor in series with the leads to the stick pot. I did this on the center wire of my DX6i and it had absolutely no effect ( I realize that it should have decreased the throw if anything).
I do not think that there is a way to do it in software. I am looking for a way to do it in hardware.

Thanks

Sorry, I should have been more clear. Even at full Travel Adjustment, the servos do not have as much throw.

I figured John's answer wasn't what you were looking for.

An experiment you could try is to open the radio and turn it on, along with your model. Then push the stick all the way to one side and see how much servo deflection you get. Determine which direction the potentiometer turned, and while holding the stick, bridge across the center (wiper) terminal and that end terminal to see if you get more deflection. That will tell you how much deflection is theoretically possible if you can somehow replace or modify the potentiometer.

Be sure not to bridge the wiper to the wrong end terminal. You can use a voltmeter to find the end terminal that has the lower voltage to the wiper when you push the stick to the side, and that will be the side you can safely bridge.

Another possible solution might be to modify your servos.

the DX6i is a computerized radio, so simply modifying the pot wiper voltage may not get the travel you're looking for.

Spektrum probably didn't want to overdrive the servos when the endpoint adjustment was set to 125%, plus subtrim set to 100% (30 degrees of travel according to the manual,) plus normal trim setting, plus channel mixes. So you may not be able to get 'full' servo travel on just sticks alone.

Did you try setting the endpoint travel to 125%?

You can also try to recalibrate your stick travel, but at your own risk! http://www.rcgroups.com/forums/showthread.php?t=905561

This will keep me busy for a while! THANKS!

Thanks. I will try this first.

I've seen pix of guys extending the servo control arm by screwing a home-made longer one on top. RG

I usually go for the old fashoined approach and use a longer servo arm and or move the other end down to a hole closer to the control surface.
Some servos do not do well, if you try to over drive them past their normal range. You might try a different servo or brand of servo and see what happens as some servos come from the factory without a lot of travel to them.
