XK110 Pitch & Thrust Settings

[Rocketman777]

I am back into RC Helis again after a three year hiatus. I bought an XK110 which is my first CP HELI and using the 6 gyro stabilization mode. My orientation skills are ok and have had no major wrecks and getting used to turning off the TH before impact. I am finding the current pitch and thrust setting to be a little touchy. What beginner/intermediate setting for both pitch and trust do you recommend when just getting back into the swing of things? Thanks!

I highly recomend Changing out the normal 0-100% throttle curve, to something that does not spool up more above half stick,.. ie: 0-30-60-60-60. This will alleviate the xtra torque that happens when you collective up,.. and the motor tries to raise Headspeed at the same time!

As far as pitch,.. I recomend most to go with an even pitch curve so that there is the same amount negative as positive, and Center Is Always Zero Pitch, especially if future plans include 3d flight. If normal setup has pitch curve of -100/+100 you could ease it a little more gentle with -75/+75 or more -50/+50.

You also can increase your expo settings to make cyclic stick feel more gentle around center stick, but still allow for full movement(100% Duel Rate) in the case of needing to get out of trouble!

I would not tame it down too much, as it might force bad habits, but rather,.. just practice, practice, practice and it will get better!

Normal:
Pitch: 40, 45, 50, 65 ,80
Throttle: 0, 32, 65, 65, 65

Idle up: (allows inverted flight)
Pitch: 20, 35, 50, 65 ,80
Throttle: 75, 75, 75, 75, 75

Expo: -30% (The XK X6 uses negative expo to soften response at stick center)
DR (Ail & Elev): 50% (be sure to set both sides of each stick axis - up and down and left and right each have their own independent setting.)

You may need to adjust the flat portion of the throttle curves up or down a bit depending on how the ESC is calibrated.

I'd also recommend calibrating the sticks on the XK X6. This is a very simple and easy procedure that takes all of 60 seconds. I did a video last year showing how this is done...

XK Innovations X6 Stick Calibration (0 min 36 sec)

You'll also want to calibrate the 6G and 3D modes on the K110. This is covered on page 1 of the RCG thread...

XK K110 3G/6G Small CP Heli thread

Quoted the calibration process here: (Note that I've added some additional steps (in red), based on my own experience.)

...Calibrating the 6 axis/3 axis gyro

Like the V977, this copter has the option to adjust the hover in 6G mode. As the manual isn't too clear on this, I was happy to see member Anderu come up with a translation of the manual's "borken chinglish"


To tune the handsfree hover in 6G mode, try this:

1. Switch on TX
2. Switch on K110 and wait for it to bind to TX
3. Switch to 6G mode
3.5 Set the DR switch to HIGH setting (+/-100%).
4. With the throttle stick down, pull down the elevator stick and hold the position
5. Wait for LED (I did not check which one) to blink
6. Lift off K110 and hover it in one spot
7. While the K110 is hovering in one spot slowly land the heli and keep the throttle at 0
8. Pull down the elevator stick again and hold the position
9. Wait for the LED to stop blinking and you're finished with the calibration


I've not tested 3D gyroscope calibration but I'm sure the steps are like below :

(MODE 2)
1. Switch on TX
2. Switch on K110 and wait for it to bind to TX
2.5 Set the heli on a level surface and add shims under the tail fin to raise it until the tail boom is level.
3. Switch to 3D mode
3.5 Set the DR switch to HIGH setting (+/-100%).
4. Move and hold the throttle stick to the bottom left location. At the same time move and hold the cyclic stick to the bottom right location.
5. Wait for LED (I did not check which one) to blink
5.5. Once the LED starts blinking, return the RUD, AIL and ELEV sticks to their centers.
6. Wait until the LED stop blinking and the gyroscope calibration is complete

Remember that you need to set the dual rates (DR) to +/-100% to be able to enter the 6G and 3D calibration modes (it won't work if DRs are set to 50%)

Hope this is helpful!

Thanks!! Just set everything up on the X6 as directed. I won't be doing any inverted flight for awhile!! Will test it out tonight.

Hi Ridge-Runner, thanks for all the informative posts
I have ordered a RTF K110 to primarily practice my backward and inverted orientations and circuits and was just wondering if you would still recommend these settings- not really interested in 3D more smooth flying in all orientations.
Thanks for your help.

Yes!

With the constant, reduced headspeed and softened collective pitch response, the tamed K110 is completely flyable indoors (hovering).

As I said in that post you quoted, be sure to reduce the Dual Rates on both sides for the Ail, Elev and Rud channels, i.e. Ail left and Ail right each have their own setting - same goes with the Elev up and Elev down and Rud left and Rud right. I'm still flying mine with 50% dual rates after a year and a half - (on full rates this thing is VERY twitchy!) I'm still a non-3D pilot (a slow learner) and am still working on my upright orientations.

Regarding spares, at a minimum, be sure to get some extra main gears and main blades - those are the parts that I've found routinely give out on mild crashes. The main gear will last quite a few crashes before it needs to be replaced - on most crahes, you'll simply need to push main gear up against the lower main bearing to eliminate vertical play in the main shaft.

Good luck! (You're going to love the K110 )

Thank you, greatly appreciated

Sweet I have a xk k100, and am going to get the brush-less, xk k110, I have heard some bad things about the xk k120 though..just wondering what your thoughts were on that model heli??.....

[BrokeDad]

If you don't crash hardly ever the K120 is great. Once it touches anything but air get ready for repairs and bad servos. I know as I have one and a half of a K120. Get the K110 and a lot of spare main gears.

[Flo422]

I have 2x K110 and 1x K120: After about 100 flights with the 120 I rarely crash it and when it happens above (somewhat tall) grass I can continue flying about 1 of 2 cases. Key is to reduce the head speed because it's insane on full throttle (my opinion, doing beginner level 3D currently rainbows/tic-tocs/rolls/loops/flips mixed with inverted fast forward flight).
I'm using a 70-80% throttle curve (70% in the middle, 80% on max pitch).

Cool thanks, got a master cp too soon and found out the hard way as well... , just got it repaired last night , now for dialing in the devo 7 trans on that one..But back to the xk k110 gonna get one for sure,because I have a xk k100 falcon and just friggin adore that Little steel Sh**!!....
So got another question for you , the little brass main motor gear came off after ahummmm...let's see how should I put this??..."Extensive High Altitude Bleeding Edge Flight Recovery Tests".........hahahahha... didn't brake the k100 but on the next flight it came off mid flight..., you know how small that gear is , and brass not being a magnetized metal, well You can probably figure out what didn't happen..So I found a place on the web , called...
linparts.com..., anyways they have that motor gear set for the k100, Couldn't find it anywhere else go figure... but long winded as I am..,
I am looking for the glue , to use to put this motor in the air-frame, what was there before, was like an white paste type, which I am sure is probably a Thermal compound as well because it is a brushed motor, heat Heat HEAT..., So would you or could you point me in the right direction on this one ,I don't really want to use, ca, nor 5min epoxy, in case I have to replace the gear again, crazy , they got that gear for the k110 brush-less motor, but not the k100, brushed motor on ebay for like $2.35 U.S. But I had to get the motor and gear as a set.. I'm pretty sure there is another little heli, out there using this same motor set but, I know this is the right one for the k100...,
Also I checked this guy out on youtube.com a while back and am using his kx x6 trans settings because I like the way the heli handles with them...
I would like to know what you think....about this guy's settings...An thanks for your help in this matter sir....jammer Helifreak noobe.....
