Beta Firmware Update

We have just released a firmware update. The main ic is for what some people are calling "gimbal smash". Please be advised that this is beta software and care should be using while testing.

We are still working on a major release including gps performance enhancements. However, A member of our team has a serious family issue to attend to this week so release will be delayed.

Cool beans Al. Although Im still a few weeks away from working on my gimbal again. Ive posted this before but thought this would be a good sp[ot to mention it again. Someone has been working on gimbal issues with a mod for PH AV200 gimbals which may help people with other gimbals as well.

AV200 Roll Enhancement.wmv (3 min 11 sec)


Also a thread here he started on multi rotor forums

http://www.multirotorforums.com/show...ll-enhancement

Possibly there could be info which may help with general gimbal issues

All the best to the HF person mentioned.

They claim to did a research to arrive at those improvements. Really looks the did a re-search all forums arround and mostly here. Voltaje as especified by the servo manufacturer an HF team. Three turn vishay pot as stated here with reference included. Well they fit a 72 gear may be the only real thing but looks to me they don't really understand how each mod affects the particular behaviour.

I did the three turn pot and the 72 tooth gimbal mod. I also run my servo at 6 volts. The difference from the original was amazing and makes me very happy. I am looking forward to trying newest firmware release.

What 3 turn pot did you use? I tried a 5 turn and was "meh"

Same brand as original just three turns intend of 10. I forget brand name but I think I picked it up at mcmaster Carr.

I just did the firmware update and I have no control of gimbal while adjusting gimbal in setup mode. Was that on purpose Al?

If it is on purpose it will be difficult to setup perfectly, but I will say the new firmware looks great on the ground. No gimbal smash on boot up, seems to stay very level through it's range. Looks very smooth. Now to fly when the sun comes out and see what it does.

The Gimbal now arms when the HFP is armed.

Sorry no explanation. That thread is controlled by George and he is out for a week or so.

Tilt and roll seem to work well with our AV200 on the new version. I'm hoping to give it a fly tomorrow. I did note we now have to have a RX connection for tilt, not sure which version this came in on. The earlier versions the tilt and roll could simply be connected to the HFP. With no tilt RX connection tilt compensation is off.

I still don't get real time adjustments of the gimbal in setup mode. I have to guess now if I need to center the roll axis or make any other adjustments to the parameter settings. Is anyone else having this problem? All else works fine when it is out of setup mode.

Anyone?

I havn't changed my settings from when we were running 2.366. They seem to work fine for now on the later versions. Any minor variation in "zero" or level I just turn the external pot.

As a short term fix, try one of the earlier versions to set the roll and tilt and then re-load the latest. I guess if you have done the cal then don't go below 3.1.448. I think 3.1.448 still allows for roll and tilt.
