Is anyone using a helicopter setup on their Tx to control their quad?

I'm interested in your throttle curves.

Could you share your Tx setup?


Thank you!

I programmed a custom throttle curve for my Tricopter. It uses no expo, but when my throttle stick is at rest, its transmitting 30% throttle. The throttle stick centered is 50% and with the throttle stick full forward its only actually 70%. This makes it very easy to keep my Tri stable and not want to fall out of the sky when I descend, or skyrocket off the ground when I take off

I am using a Turnigy 9X with the ER9X firmware.

sorry i left the project in school. it looks similar to this though.

Kk Single copter (1 min 27 sec)

Thanks Subaru!
I'm using the same Tx, that's exactly what I want to do.

Are you using aero or copter mode???

The ones from Dimension Engineering can be connected in parallel:

Checking gyro direction is easy. Take props off, give 50% throttle and tilt the frame in roll and pitch plane. Motors moving down when you do this shall speed up.

im doing a single copter with 4 servos and i was trying to find answers to the following questions:

1. does the P and I LIMIT have to be less than the P and I gain themselves? I cant really tell the difference when i change the limit settings. hope someone can share what the limit does? (i dont quite understand the video when he says it's like travel adjustment)

2. Im using hitec hs55 9 gram servos and i have set my servo filter to 50. what do high and low servo filter values represent? (i could get them to work at 1 - 80++ servo filter values).

thanks in advance to any kind soul. very happy with my kk board

I fly my KK2.0 on my DJI clone in Heli. On a DX8.
Idle up position:

0: 0-25-50-75-100
1: 15-25-50-75-100
2: 20-30-50-75-100

I use 0 position for regular flying, and was playing with positions 1 and 2, for stunts. Leaving the props to spin slightly to do tighter rolls and flips. Figured it's kinda cheating though.

On the KK2.0 v1.2 I do have the Quad X selected, Auto leveling turned off and all other settings are stock. I did calibrate it, calibrate the ESCs several times and also made sure my sticks are going the right way in the receiver test menu. First time I been stuck with rc

Here are some pics of how I have everything wired up (white arms are the front of the quad and its kinda hard to see but ch5 goes to ch5 on the kk board - I was getting it set up for switching the auto level on and off - but left it alone now since it cant even take off lol) ...
Good,
instant flips are usually due to reversed gyros or can be incorrectly connected ESC's
With KK2 firmware, another possibility is that the mixer settings have got corrupted and this could effectively 'reverse the gyro(s)'

Your pics look OK btw

Maybe take thinks one step at a time:
remove all but 1 propeller
arm copter
now hold the copter with one hand and slowly increase Tx throttle to ~30% (<- plz be careful when doing this step!)
it should roughly maintain a constant speed and when you push/twist down the arm with the propellor on, it should increase speed to resist. If it doesn't and immediately mis-behaves, then the setup is wrong
repeat this for the other 3 arms.

Broken accelerometer?


Crashed your KK2?

Can't calibrate due to bust accelerometers?

Then you need my latest version of code which removes all accelerometer (self level) functionality.

It's been tested with video evidence

This won't fix any problems with the gyros (you really do need those) but hopefully will breathe further life into some KK2 boards.

The original menu item was only a text description of how to do the ESC calibration, its been removed to free up memory.

Just do the same procedure as previously.

Tx on throttle full.

Connect battery then immediately hold down buttons 1 and 4 (keep holding them for entire procedure)
(some people have to hold buttons down while connecting battery)

Wait for program beep from ESC's then put throttle to Zero.

Get another program beep from ESC's then disconnect battery and switch off TX.

Done.

I made a video on how I calibrate my ESC's.

Calibrate ESC's using the KK2 Board (0 min 50 sec)


!!!!REMOVE ALL YOUR PROPS FIRST!!!

My ESC's aren't very loud, but you can hear the beeps.
