"I am trying to configure this zubax gps and am having problems. While looking at the Params list in Mission Planner I can not locate the BRN_CAN_ENABLE parameter on the latest firmware. Please help."

Hello everyone,I have been working on a heavylift quadcopter for some time now. I have used U8 Tmotors on 6s and had good success with flight time but suffered in stability. I have been looking to change to the U10 Tmotor or the KDE 7208 or 7215 mot…

"I found the the was a glitch with the firmware. I flashed the firmware to use qground control and then flashed back to use Mission Planner and the problem went away. You do not need to do what I've done but I would try a clean flash of firmware.

William Cox replied to William Cox's discussion Unequal battery draw with lipos connected in parallel
"In my case (I don't have a clue, lol) I have a four station battery charger. I plug one battery in to one port. I guess everything is entitled to an error or two.

At this point with these batteries it is a moot point. if you follow one of my other…"

"Well I found the problem to be that the charger stopped mid charge. I restarted the charger and it finished within a couple mah of the other one. It doesn't give me warm and fuzzies for it to do this.

Thanks for the hell anyway.

"Sorry for the rough drawing but here you go. You want it this way so that the monitor measures the draw of your BEC.

William Cox replied to Damian's discussion Power module with AttoPilot 180A to Pixhawk in PIXHAWK
"Damian,

I would hope so. To pull more than 90a you would have to be swinging logs (tree Logs, LOL) on the motors. I looked at the spec. sheet for the motors. If you pull 100% throttle yes you could exceed the 90a max (AttoPilot Voltage and Current…"

"Damian,

the input connections from the BEC need to come from the batteries. from there connect the BEC and attopilot like this:


The input side of the BEC is not shown in this picture but it would be on the left side of the illustration. See this…"

William Cox replied to Damian's discussion Power module with AttoPilot 180A to Pixhawk in PIXHAWK
"Damian,

This configuration will not work. The connection from the attopilot board is a metered signal not a power sorce. You will need to pull power from the battery. Make sure the bec can handle the 6s voltage. If you want to eliminate the weight…"

"Hello,
I hope you are ready for a challenge. Once you start to get it right it is very rewarding. The first thing I can say is frame ragidity is most important. Check vibration levels using your logs. X and y axis should under 3 g's. The z axis shou…"

"Hello,

I would suggest this power module that way you have some room if you want to go up to 10s.

Just make sure you check that they soldered the connector on the right way."

I hope the charger had a bad day. I use anti spark plugs for the very reason of reducing spark when connecting the batteries. I am trying to come up with a reliable way of logging power consumption of the batteries a…"
