Tried to flash to the new version from 4.5 without success. My Quad went completely crazy. Wanted to revers yaw but it didn't work in the way it did before. Is there a new setup routine which I missed ?

Cheers,
Ralf

I have the KR red board with esc Turnigy plush 18A and 2.4GHz JR DSX-12 with AR-6200 receiver.
Just went back to version 4.5 a few minutes ago to check. Everything works fine. With 4.6 everything is going wrong, gyros for nick and yaw have to be reversed. Also the trim needs to be far out of the center.

Cheers,
Ralf

just noted another strange behavior. Motor 1 on the + configuration doesn't start correctly. Only after applying nearly full power for a short period it's running fine. This also doesn't happen on 4.5

really strange...

I tried the 4.6 on my KR red board with 18a Hobbywing (the same as Plush) and with bit time beaten up 2217 turnegy motors.
And it flys like a dream..
I use a futaba 9c with a 149 RX.

The thing a had to do was:
-Connected the motors like this: http://www.kkmulticopter.com/index.p...-faq&Itemid=41
-reverse the throttle channel in the RX (ordenery for futaba)
-Taking in consideration that all the potts are reversed
-Calibrated the ESC from the card.
-reverse the yaw gyro.
-sat the gyros at ca 40-50%

good luck

did exactly the same - but no success. The biggest issue seems to be the startup of motor 1. Already swapped esc connectors to check. It's for sure not the motor or esc.

Ohoy Kaptain....sadly I dont own a single + frame quad, so I will patiently wait for you to introduce a new Tricopter or Xquad software...

Here is something I have been tinkering with - hope you like it...it flies with tricopter 1.5 software, but has the usual sluggish stick response and very high gain scaling known from the WMP mod. I did not get around to changing the gyro or stick scaling yet...

I would also like to hear your opinion about the HW LP filter and possibly tuning the software to the 500 degrees/s output from the Invensense 500 gyros..so a few of these is coming your way of course....

Thanks!

As stated before, it is possible to change the direction of the potmeters. Just enter gyro reversing and move the throttle up.

Hello, I like the size of that one. What about the LP filter? I can tune the firmware for it, no problem.

Thanks, I knew I could count on you..

Can you send me you adress in a PM. I will get them out to you tomorrow.

I have used the resistor/cap values suggested by the datasheet for the external LP filter (750R/0.1uF) But I am unsure if this give a lowpass that is suitable! According to my calculations Cutoff freq is 2122Hz with this....

Hi,

I think you want to see this one !
Can't imagine the result if i will implement it on the pitch and roll axes...

PS: sorry for spamming this around the different groups, i think it could interest some people...

Here is the new QuadControl V4.7 (plus and X mode) firmware.

The poor atmega48's memory is now full

Changes:
Higher ESC refresh: 300Hz

Added I-term on yaw axis

Added I-term anti wind-up, all axis

Changed potmeter usage:
Roll pot now controls P-term gain on roll/pitch axis.
Pitch pot now controls I-term gain on roll/pitch axis.
Yaw pot controls P-term on yaw axis as before. Yaw axis I-term is fixed at 0.2

X-mode setup:
Motor 1: front left, CW
Motor 2: back left, CCW
Motor 3: Front right, CCW
Motor 4: Back right, CW

Suggested initial setup:

P pot at 50%

I pot at 0% (it can be left at 0% since it does not have a secondary function.

Yaw P pot at 50%

Trim it level.

Adjust P (roll/pitch) to your liking.

Add I until it flies straight forward without pitching up.

Probably I wind-up caused by out of trim.
Use the new V4.7 and follow the setup guide.

The gyro you use has a internal 140Hz LP filter, so you can use those values.
