So after two weeks of on and off building...the new King has been born...to all ESKY stock configuration. Specs are:

ESKY 2.4 gig TX/RX taken from Belt CP.

Sg90 servos (4)
ESKY gyro.

I setup the heli with idle up and mid stick with are servo horns 90' degree...check pitch at high 9+ and low -9.. with two knobs at mid position.

Problem encounter:

Back to Normal mode at low stick I get +4 pitch and +11 at high stick, at mid stick I get +7 and 3/4 stick I get +9....so I know that the pitch and tooo much and thats why the heli lift at mid stick <---- I KNOW there is definitely something wrong here...WHAT is wrong with my setup....seems like everyone and everywhere I read to setup with ESKY 2.4 gig stock radio and receiver they stated the same procedure to the setup I stated.

In IDLE UP mode everything is normal like it suppose to be...but when flip to normal mode everything went out of wack again.

I am tempting to go out the box and re set the heli up in normal mode instead of idle up mode....

Any help out there?

I've done about a dozen ccpm setups and i stay in normal mode, midstick, and motor unplugged. Honestly, mine has always been setup with more positive pitch than negative, just cause i like to have it lift off without having to jam the throttle stick almost all the way up. In your case since the Esky tx is not programmable for throttle and pitch curves, i would for sure do that.

I'm right now in the process up building a totally stock K-3 with all the original servos, esc, tx, rx, and pretty much going back to the beginning. Just want to see if the K-3 is flyable now that i have some experience. Got the frame together this morning, and will have the rx and esc attached by tonite. Over the next couple days, i'll be right in the middle of it, so should be fresh for any problems youre going thru.

Generally speaking, If you want more positive than negative pitch, the servo to swash links are longer. For more neg pitch, shorten all three links. Lets build some K-3's.:thumbup:

Like....you can't setup a heli in normal mode....when setting up a heli the pitch curve has to be linear...so IDLE up mode puts it to linear so you can do the setting...than switch over to normal mode...but my problem is when I switch over to normal mode the figures are all wack out.

theone,

Your setup sounds right as you said. Could be your transmitter is a bit out on trim or other "adjustment". I assume your trim tabs are all centered?

I flew one of my King 2's all last winter in a parking garage using the stock 2.4 radio even though it was mechanically set up for the DX6i, I recall not having to change much, other than moving the servo balls in a couple holes to make up for not having a swash mix to adjust. I did not want to keep the good radio in the trunk in the cold weather.

I think if you experiment with knobs on the top of the transmitter using your pitch gauge, try adjusting the left knob full negative. This should bring the entire pitch curve line down 2 - 4 degrees getting you near where you want to be. It should be named Hov Pit. My transmitter has another knob named Pit Trim on the right that changes the center of the pitch curve either delaying the onset of pitch (-) or making it happen faster (+). The newer transitters I hear have a gyro gain knob instead of one of these knobs. Try Hov Pit full negative and measure with your pitch range. You could also try some negative throttle trim. Seems like when I once measured the receiver outputs and found that throttle trim trim brings down the pitch range quite a bit.

BTW, the stock transmitters apparently eventually break a melted joint at the gimball where the trim adjustment attaches. Mine would jump about 4 degrees on small elevator inputs. There is a fix posted somewhere by a guy from New Zealand on how to fix it, but it seemed like alot of work. Expect about 100 flights if you baby the transmitter. I switched back to the DX6i, as the swash mix alone was worth it. Being able to trim the amount of elevator and aileron pitch independent of collective makes a huge difference on the King 2.

Hope this helps.

theone,

I thought the trim next to the throttle is always suppose to be at the lowest position when setting it up so I left it alone to the lowest position....other than that yes all trims are at middle. So I took the whole thing apart again and set it up in normal mode like LIKE stated and test flew it that way...I know there is something wrong there DAMN IT!!!

Gmorning all. :cheers So to2007, did it fly when set up in normal? I finished mine last nite and will test fly this morning. Its 100% stock, like yours. It was set up in normal mode, with all links set to the manual specs. The initial pitch readings were,
low stick +3
mid stick+7
high stick+12.
idle up +13 to _9

I cranked down the servo to swash links by 2 turns each and readings were:
low stick +1
mid stick +6
high stick +11
didnt check idle up

Cranked the links down 2 more turns each.
low stick -3
mid +4
high +10
idle up +10 to -10
Thats where we will do the test flight, and will post results later today. :smokin:

Heres the very 1st flight to get the trim set. Tail had a bad left drift so flopped it down for an adjustment, went the wrong way with trim, and had to flop it down again. Then i was able to make rudder trim corrections on the fly, but it needed about a half a battery before the rudder trim settled down enough to try some simple moves, and even then, the tail needed almost constant small trim adjustments.

I hooked the throttle once miday thru the vid while reaching for the trim buttom and she dropped fast. Aside from the lousy gyro, this is a decent flyer. It needs a couple flybar weights to help calm down some of the jerkieness, but it was stable, steady, and had good power. The stock tx worked fine, but i missed having the Throttle Hold switch and some expo would make it smoother without flybar weights.

All in all, if it had a somewhat decent gyro, this would be a great machine, but needing to concentrate on the tail every second takes my attention away from other things. The crash looks bad, but nothing was hurt at all. :) Tore some plastic covering off the blade ends, but a little glue, and rebalance the blades, and shes ready to rock n roll. I THINK my homeade tail link may have come apart to cause the crash. I glued one end on, and it was 'unglued' after the crash. I was still fighting with the tail tho, so maybe it just got away from me too. Happy flying.:YeaBaby:

Nice flying!!!! I trash the entire stock bs and went with DX6i/AR6100 and problem solved..hahah

hi all...theone i had the same issue with the king 3 stock tx, ended up with a futaba 6ex.
hi lak, no wonder you crashed trying to trim the heli in all that down wash, u need to have it over waist height really to trim it, shame about the crash tho :arggg:.

I am glad you did...I was trying to use all my resources before pulling out the DX6i...Can't believer I gave in to ESKY and waste my time like that.

yes, the stock controller leaves alot to be desiered, that stupid knob to speed up the blades is a joke :roll: .
so glad after i got the 6ex set up, makes the king fly nice if thats possible :)

The funny thing is I have the other stock BELT CP 2.4 gig TX/RX and set it up just like I stated and it came out perfecto....hahaha
