Hello. Just joined forum. I am hoping to learn alot here. I just got a mcpx and a dx6i. I can get it to hover pretty good now but flying around is a little tough. I heard you can adjust away from stock settings to make the helicopter fly a little less sensitive. It would be so much better for me to learn on but I do not know what to set the numbers at being new and all I am hoping you guys can help. Also the whole dr/expo thing i still don't quite get. what it is and how to use it. If that can be explained that would be great also. Oh and if anyone in the long island area preferably Suffolk county knows any heli clubs. Thanks.<div>-Jeff</div>

I've got an MCPX and I used the values provided in the manual to program the thing. Given I already know how to fly, but I was able to flip it inverted and do all kinds of maneuvers with the values in the manual. Not fine tuning anywhere.

Are you using the "bullet" blades or the straight blades? The bullet blades are a lot more stable than the straight blades.

Let me try to explain Dual Rates (D/R) and Exponential (EXPO).

Exponential is used to "soften" the movement of the servo around center stick. Sice hovering takes a lot of minimal corrections around center stick, depending on your settings, you could be over correcting when doing those monimal corrections. So the movement around center stick is reduced by a fraction but you still have all the available servo throw programmed on the servo travel screen. 100% servo throw.

D/R is a reduction or increase of the total servo throw. If you program your D/R to less than 100% you are reducing the servo total movement to the number programmed into the D/R. Some radios allow to go over 100% in the D/R programming. I would advise against this, but it is your choice. If you go over 100% D/R you are increasing the servo throw. This is the total throw of the servo.

Now to tame the MCPX, I would suggest leaving servo throw and D/R as indicated in the manual. You could play with EXPO to get the helicopter to behave a little better. If using a JR/Spektrum radio, positive (+) EXPO makes the center softer. On a Futaba radio negative (-) EXPO makes the center softer.

Hope that helps a bit.

I cant remember for certain...but I think the setup in the manual for DX6i and 7 already have suggested EXPO @ 30%.  Dont take my word for it as Im relying on memory here...and its definitely not what it used to be! lol
