Two batteryes using

[studiopetros]

Can you expand for a two batteries using ?
I am using a 12v camera and 12v transmitter. I think I was read someware that the RVOSD will choise the battery who have a higher voltage. is that right?
Have to take off the jumper "main battery disabled"?
What is the better choice for me?
Thank you

I am using a 12v camera and 12v transmitter. I think I was read someware that the RVOSD will choise the battery who have a biger volts. is that right?

I'm also using the 12V camera and 12v transmitter. I use two batteries. The big one (3s 5000mah) connected to Main Batt port, and a small one (3s 600mah) connected to Aux Batt port on the RVOSD.

Since the motors are running off the Main Battery it normally always have lower voltage than the Aux Battery. This way the camera and transmitter are powered by the Aux Battery, while the Main Battery is used for everything else, minimizing interferences. However, should the Aux Battery voltage drop below that of Main Battery voltage (for example Aux battery is empty or fails) the RVOSD will switch the camera and transmitter to be powered by the main bat.

3s 5000 mAh on the easy star? I just order a couple of those and would love to know how much flying time are you getting.

I have a Twinstar II for my FPV set-up. My flight-time is around 45 minutes on this pack I think.

I've only done like 10 flights on this set-up, mostly with couple in-between landings each flight and a lot of playing with various setting on the RVOSD, so that this is not yet representative

Managed to adjust autopilot and AHI to work ok?

Not really. First of all I don't have the FMA sensors, as they are not in stock till mid-May

I've been playing around this weekend with various autopilot settings, trying to make it work without AHI. Sometimes, it actually seem to work - the plane kept altitude and headed more or less in the direction of home in autopilot mode. But sometimes (on the same settings) the plane would go down in spiral like crazy. Anyway it was rather windy over the weekend, so I have not really expected it to work well. I will be trying again this week, when there will be no wind.

Do you it should be possible for RVOSD autopilot to handle Twinstar II reliably without the FMA sensors?

Better wait for the FMA heads, with them you are much more covered and adjusts are more easy.

Thank you for the answer Pit3k. So what will be happened if the main battery failed?
My set-up : easy glider multiplex, 2450main, 1000aux, flying time about 30 minutes
Not trying yet the AP.

Hi Alex.
I have read this Setup Guide, but there is not example for use 12v camera, 12v transmitter ,3s main and 3s aux battery. Have I remove the jumper??
