Blade CX2 Setup - Worked for me!

[-=JK=-]

Found this setup advice on another site.

Makes sense, and has helped get my CX2 into a stable hover, which it wasn't doing out of the box.

Quote - "

1. center the gain pot setting

2. center all trims tabs

3. (if programmable radio no sub trim)

4. using the throttle trim tab.. push it forward until you hear the motors start to hum and then one blade starts turning.. adjust the motor potential setting to get both turning the same at that low throttle. (remembering to unplug the battery, adjust & then reconnect)

5. throttle up to a hover and adjust the gain for left or right drift..

6. if that doesn't work.. repeat only overcompensate for the drift by adjusting the motor potential to start that motor first. all else fails.. the motor is bad."

My CX2 needed full clockwise on the potential to get both motors to start at the same time.

From there, it was straight into the "stable" hover that i'd heard so much about, but had never seen.

Just thought i'd pass this on to anyone else that is struggling with the usual clockwise yaw that seems to be part of the ownership experience.

Put two batteries through since the change, and it's MUCH better.

where did you find that jk cos its not right. the bottom blades should start before the top set and run slightly faster! if they start together you will get a clockwise drift.
if as you say your pot is adjusted fully right im afraid you may have a problem!

it is far more accurate to adjust the potential by hovering and adjusting to eliminate spin!

Having just repaired mine this morning after a little ding this week, I agree with Ron. In fact the book (pages 31-34 I think) are spot on and easy to follow. Main thing to remember is that when ever you adjust the 2 into 1 unit you must unplug the battery and recconect for the adjustment to take effect.

Hi Boggy,

The bottom blades do start first with how mine is set up. I don't think it's possible for it to be otherwise (i stand to be corrected).

This advice was from an american site, can't remember which one.

I was suffering from a clockwise yaw, as well as a loose tail. Since setting up as mentioned above, the heli doesn't yaw at all, and the tail stays in the direction i put it in, not moving at random.

I'll take a look at the book, as mentioned.

If the setup is wrong, then it obviously just works for my heli, and makes it the most stable it's ever been in my 2 weeks of ownership.

Maybe i got a duff one. I have a pair of upgraded motors to play with, so will see what happens when i try them :-)

That's strange, my top blades start first....

I hear that mate.... I'm leaving well alone, I've just got her flying perfect again. Now I've got to strip the Skylift, she's got a heckuva shake on the rear rotors, but only when they're all put together, flybar don't do it. Naked shaft don't do it, but add blades and oh boy she's shakin' herself to bits.

i know it might seem a bit obvious but if everything is ok till the blades are on
check tracking or blade ballance
