lock-in altitude hold with switch??

[nealj4]

My hexacopter hovers excellent at the designated 50% throttle ( Naza v2 with gps) but very sensitive when I try to yaw for photo work. I read another post somewhere that someone had the idea of flipping one of my spare switches on my transmitter (spektrum dx7i) to set the throttle to 50 % while I pan around. Will this work and how do I do it??
Thanks guys.

Instead you can have the throttle stick self-centre (mine does). Open up the transmitter and adjust the springs then the throttle stick behaves like the cyclic stick. There's online tutorials for many transmitters.

Or use a custom mix that activates with a switch position. I would think throttle to throttle would do it.

Thanks "Old Man" that work perfect.!!

Glad that worked for you. Another method if you don't want switch dependency is to use the TX exponential function to soften yaw response around center stick position. Some transmitters will also permit this for the throttle channel. If you try that you will need to use a little ore side stick to initiate yaw response but it all comes back to "normal" response as the stick moves further from center.

Yes , I am using some expo on yaw. It works very well, but my throttle is very touchy which is why I want to lock the altitude in so I can pan around for AP work. Because my radio is set up for airplane mode for MR ( I don't know enough about this stuff as to why) it does not offer me expo on the throttle channel. The only little hiccup now is when flying forward quickly the MR loses altitude. ( physics I guess) so I have to keep nudging the throttle up every few seconds. Not a huge deal, but would love to overcome that problem as well. I am using Naza V2 with GPS, I have read that another 1000.00 on a flight controller could take care of that. HA HA!

Don't know what transmitter you are using but if it has a slider on the side of the transmitter you may have one more option still. It may be possible to assign the slider to the yaw channel while still maintaining the throttle stick as the yaw channel, in essence providing two locations to use the yaw function. If that can be done you could use the slider for camera control, separating it from any interfering with the throttle side of things. However, if what you are using works well for you then leave as is
