hey kmargos

congratulations for building it, nice job

and good video!

it very nicely shows how it performs in pitch pumps
the video also very nicely shows the backbounce, since it's just one short pronounced backbounce you seem to have adjusted your PID gain and PID I quite well... so, you're video is kind of a good tutorial on how it should look like then PID I is properly adjusted

in order to get rid of the backbounce, you just activate the debounce mechanism (with Debounce CCW=30 and Debounce CW=0 it is inactivated, see the above manual chapter 5.2.) by reducing Debounce CCW step by step (usually a good value is inbetween 7-12)... repeat your turn tests and you will nicely see it's effect, i.e. how the machanism suddenly "anticipates" and eats away the backbounce. With just adjusting Debounce CCW you should be able to get rid of most of the backbounce in both directions (if the mechanics and servo end point parameters are set up well). You might be happy enough at this point. You may however also go in a fine tuning and also set Debounce CW to values above 0 and below 30 for adjusting the debounce in both directions independently. Don't touch the De-/Acceleration Limit values (see chapters 5.2, 5.3)

since you're obviously airborne, may I put you on my list on my web page?

cheers, Olli

Tanks Olliw, I'll follow their advice.I'll try to record more videos tomorrow

Can put me on your list

The original firmware cannot be saved. The processors lock bits are set to protect the original firmware.

Hi olliw ,

Comparing with gyro firmwares manufactures and home made.
Configurations:

Gain Input=Set Gain& Mode
Gyro Mode=Heading Hold
Rate Gain=0.7
PID Gain=0.8
PID I =10.5
Debounce CCW=10
Debounce CW=10
Decel Limit R =30
Decel Limit R =0
Rudd Mid Mode= Auto
Rudd Mid= 00us
Rudd Dead Band= 08us (I think 8us for DS 525 align is better)

You can share the video, if you want

HK 500 GA 250 Olliw Firmware Vs Align 500 Original Firmware (13 min 40 sec)

Hi olliw ,

when increased the D / R rudder on the transmitter above 60%. I move the stick and the helicopter starts to spin slowly then rapidly spinning the tail is out of control momentarily. This is the parameter of the RUDD RATE? If yes how to change?

It seems that the stick deliver more signal rapidly and slowly turning the tail does not follow that speed and when I release the stick the helicopter rotates rapidly to reach the calculated point.

I'm sorry for bad English, I hope you understand.
