Slowing down yaw speed on a DX8.

[ChrisH]

Hi all, I';m still very much a newbie in this hobby. Previous experience was 27/35MHz gear when it worked or not. Rates were changed by putting different horns on the linkage etc.. 

Now it seems everything is tunable on the Tx if you can work it out! 

Problem: When videoing, using a two axis gimbal, the yaw of the camera is controlled by the multi. I';ve always found the multi to be far too responsive no matter how gentle I move the stick and it results in jerky tracking. It feels like I need some kind of additional control. Is this likely to be best achieved with rates, response curves or something else?

The aim is for very gentle initial yaw changes but keep a kick at the end of the stick travel for quick orientation changes.

look for an option called RATES/EXPO. add expo to the yaw channel until it feels right dude. expo basically dumbs down the responce from the centre of the stick out, the more expo the less responsive the stickk will feel;) try adding a bit to pitch and roll too;)

Thanks for that info. As is often the case, once you ask a question, you find the answer that you couldn';t see before!

On the DX8 there are lots of switches that had no function defined on my set up. Having read the book yet again the spark of dawning was ignited. I now have 3 three way switches that give me selectable combos of rate and expo! Sw position 0 default 100/0, position 1 80/25 and position 2 60/40. This I have set up on rudder, aileron and elevator to give in flight adjustment! I somehow thought all the switches would activate functions on the Rx, it was only with today';s dawning I realised that Tx functions can be controlled as well! 

The manuals on these bits of kit are very comprehensive but you are expected to know what you want to achieve (like this) then find out how to do it. All part of the fun of this hobby and the tech involved!
