They are not showing a special tool, (lost in translation) What is being shown is the removal of the bottom ball link between the Swash plate and the Bell control arm. Simply pop off the bottom ball link and turn the link end 1/2 turn to change the tracking. I use turn buckles as it is much easier to acieve perfect tracking, and the better the tracking the better the heli will fly. Here is a link to the turnbuckle assemblies.

US HOBBY SUPPLY is a great dealer, and has a large selection of HBKII parts and CNC upgrades.
The picture on the link page showes better the adjustment of the control arm.

I know there is no special tool.....(looked like a long hex / allen driver.....just wasn't sure what part they were refering to to actually make the adjustment....Thanks.....you have helped.

2 -The rest is a request, in plain english, of the purpose / features of the Transmitter........in this order:
> Trans mitter battery LEDs: only red and yellow light up, no matter what batteries I put in....so I will assume, I'm lucky I got that??
> GYRO switch: Appears "normal" position is forward....away from you?...is this correct? And, what happens when you switch is back....towards you?
> Idel Switch:Forward = normal, back = What?
Hov Pit knob on top - left: "0" normal.....turn left or right?? What does it do?
Hov Pit knob on top - right: "0" normal.....turn left or right??....what does it do?
I have downloaded the ESky transmitter manual (which in MY opinion should have been a seperate manual in the box) and am translating as I type.

ok....that is nuf for now


http://www.rcgroups.com/forums/showthread.php?p=5863143&highlight=+gyro+sw+#post5863143

Had the same question, here's where I learned.

IDLE UP N/1: Basically lets you fly upside down and all that fun stuff. Set it to "N" ( where it should be if you're just learning) and applying more throttle increases the blade's pitch and the rotor speed. Set it to "1" and the rotor speed remains pretty much the same and you just change the blade pitch. This mode allows you to give the blades a negative pitch, letting you do things like inverted flight and autorotation.

^TRN: I guess you have to turn this on when using a simulator. If I try to flick it toward me when not with a sim, it just flicks back once I let go, so not like you get a choice. I don't have a sim so can't tell you much about this switch.

HOV. PIT: Uuumm.....refer the link above, although after reading it, I'm still not sure about this. Moving the knob does seem to change my blade's pitch. I just have it set to - for now, haven't played around with it in flight yet, waiting on a motor.

PIT. TRIM: Same as above.

GYRO. SW: As the link quotes from the manual, this one doesn't apply to this heli. I tried it in both positions, doesn't seem to make a difference either way. So I just leave it up.

I hope you know what the two sticks are, seeing as you fly giant nitro planes

POWER: Gives you super-human powers, ON ALL THE WAY!!!! j/k

The servo reversers let you reverse the controls of the sticks. I have them all set down to normal except the ELE which is set to reverse.

Also I get just yellow and red lights on my Tx too, though the greens shine a bit on new batteries, I guess they have to be completely off for you to start worrying.

BTW is it just me or does the Gyro seem to work better when set to reverse? In normal, it makes me rotate either right or left depending how much throttle I apply, I would have to continually work agains it with the stick. In reverse, it's alot more stable, the heli just turned to one side, so I tweaked the servo and trimmers. Now I just have to fix my heli gliding to the left all the time even with full trim against it.

Also what exactly does the Gyro's gain trimmer do?

Status: offline 		Training switch is used with a cable to attach to another TX so they can fly the plane/ heli if you get in trouble, same as the one on a plane tx. (thats that socket on the back/side of the TX. Your gyro switch is set away from you correct. it really make no diff as it is for controling a HH gyro and you only have a rate gyro. Your gyro gain (on the gyro) is set after you do the mechanical set up of the gyro. Mechanical setup is simple to do, if your gyro spins on direction as you bring up the power look at which way you move the rudder to correct it. Now go to the heli and notice which way the servo arm moved to correct the spin (or reduce it) and move the entire servo mount and all that direction about 1mm, and try it again. Do this till you totally run out of patience with it and about that time it will start to work correctly. Also watch that the servo is not bottoming out (the "slider" on the tail assy is not running out of room to slide). Your gyro actually is set pretty close to correct as far as gain from the factory, if you fooled with it just turn it up about 3/4 for starters. There is a finer adjustment for it but this is just to get you in the ball park for now.
Do suggest you upgrade to a brushless motor and Brusheless ESC along with a new Steel pinion gear, cost for this upgrade is about 55$ max. (Do not use a Esky ESC as they are crappy) You dont really need a gear (43t upgrade at this time as your only learning to hover and basic flight) I actually took mine off just to see what the diff was and for playing in the tennis court with my heli I can go with or without the 43t upgrade. If your heli is half way set up you can hover and fly around just fine with the stock gear and belt setup.
Here ya go on what the knobs n stuff are for:
Also you might want to download the long manual from the Esky site. Http://www.twf-sz.com (pdf format and shows the cnc head and has more contridictions then ever before )

And I had to turn the servo arm to an almost 45 degree angle towards the tail to get it to finally stop spinning.

Status: offline 		actually you move the entire servo not just the arm. Check and see if your servo is running the tail slider against the stops or the servo is running to its limit with full stick movement. If not your ok. Also you will probably have to remove the arm and center it on the servo so it points stright up and down like the picture in the manual. This done so the throw is linear on the arm and not faster in one direction then the other.

Status: offline 		Hi ya funflyer
thanks much for the info......the word file you attached opened a lil screwy, but I fixed it and printed it.

All this will have to wait, as this AM I was doing some "tweeking", got my arm in the way of that big spinning prop...(the one they installed on top o this aeroplane instead of the front, like on my "REAL" aeroplanes with 2 wings and round engines...lol)

Oh well......said arm stopped rotor, however, motor kept goin.....can you say ouchie and gear grind?.....and the wonderfull stock motor seized after it spun free for about 3 seconds.

All else looks A-OK, Brushless upgrade is on way. Hobby Shop has 10 on way hopefully in day or 2 should arrive.

Thank for your help

Status: offline 		Just got the 3900 motor.
Just out of curiosity, is it safe to run it without a heatsink? Since the whole motor spins when mounted, I just don't see how one is supposed to attach a heatsink to that.

I don't use one, it would probably sling off! I have 11 flights and right now in South Carolina the Temps are in the high 90's, but it hit 100 again today.
This is the 3900 on mine

Status: offline 		Ok got the motor attached, now i gotta hook up the ESC.
The stock ESC connected to the battery using a 2-Pin JST connector, which the new ESC doesn't come with. It's just 2 wires with no connector.
How can i take the connector off my stock ESC and stick it on the new one? Or will I just have to go buy a new one?

PS: Does it matter which wire on the ESC connects to which wire on the motor? The motor has a blue red and black, but the ESC is all red for the motor wires.

Status: offline 		i think most of us use deans ultra connectors on the battery (female on the battery lead, male on the esc lead)...overkill for the hbk2, but that way, your batteries will have standard connectors for use in other applications and for charging...if you need to connect a deans-connector battery lead to a jst, you can buy or make an adapter...

your lhs should sell deans ultra connectors...

i use 3.5mm gold bullet connectors on my motor and esc wires (see the pic right above your post)...

if the motor turns backwards, just swap any two wires, and the motor will turn in the correct direction...ken

Status: offline 		toss the jst conn as its only good for about 5 amps or so. Solder on deans conn like Ken says. Note that the deans conn the female one is the one that goes on the battery that way if you happen to out something metal against it it wont short it out same on the esc the motor gets the male conn of the bullet type. If you need pictures of what is where ask and I will take some for you.

Status: offline 		outrunners dont use heat sinks, in most cases they dont need them as 3 phase ac motors are not really hot running motors to start with, thats why they are so popular in saws and joiners, band saws that run on 220v.
