Not sure if this is any good, but Hobbyking are doing a 30% discount on Turnigy batteries for 2 days.

nice, I noticed another trick with HK, if you leave a product web page open for 10mins or so it will popup and say as you have been looking at it a while you can have a discount price

What flight times do you get ?, with two 5000mah I get around 17mins which is plenty as my puny brain cannot cope with the stress of longer.

It really does burn you out, any longer than 10 minutes is quite mentally demanding and I'm glad to take the goggles off for a short break. Immense fun though

Oh dear, there are perfectly fine phantom pilots out there but there are also a lot of complete morons who couldn't tell an ESC from a Rx. This isn't really a surprise

Edit: just seen FunkyCowie's post. Still, what a wally!

Ha. Why would you fly a drone there recreationally? o_O

DJMK4 · 27 Jan 2015 at 11:39

Just recieved the IMAX B6 and my turnigy 5000mah battery, they are quite big

Bigger than a lipo I had years ago

Someone looked at me weird when I took it out the packaging, like I was a terrorist.

What is a safe rate to set my IMAX B6 to charge the Turnigy 4s 5000mah battery? If I remember correctly set to lipo, then 5A, then select 4S ?

Then just red and black output port on the charger will have the leads I am going to butcher from the deans to XT60, which will then plug in to my battery XT60, and then the balance plug from my battery in to the balance port on the charger

What makes it even more stupid is that the guy was a government employee, he didn't at any point think "I'm very close to the White House, if something went wrong and I crashed there that would be bad".

FunkyCowie · 27 Jan 2015 at 12:08

I think it was set up, if they are just reviewing legislation for UAV usage and someone does this surely it can't be anything else. I know it sounds all 'Conspiracy Theory'.

Skeeter · 27 Jan 2015 at 12:39

If they wanted to ban drones there's enough evidence of idiot pilots already, without the need to crash one onto the White House.

Yep, correct. 5A. Not sure if the B6 will put out 5A though as it's only 50w. Will be fine though.

I have turned off voltage limits in Naza and monitor voltage on OSD.

I don't get anywhere near that - at most I think I was getting around 12-13 mins off a single 8400mAh battery but that was with the Naza voltage controls on before I got my iOSD mini which I can now use to monitor the voltage remotely and see if I can safely stay airborne for longer!

That's fair enough though given you're running two 5000's when you get that air time!

A mate did make me a cable to try running two 8400's together but the cable we think was badly wired and got hot very quickly which was bad!

How are your two 5000's wired up? Any pics of the cable you use?

Am tempted to get some extended aluminium arms and different motors and bigger props to get decent run times!

as per this - just set it to charge or balance charge and it will check the battery type before it starts.

Yeah disable to Naza limits altogether if you have iOSD. I usually land at 10.5 volts min, so 3.5V per cell, though have pushed to 3.4V on occasion. I bring bird back close to home once I go below 10.8V (3.6V) though just to be safe

I have a second battery lead with XT60 soldered on one of the ESC power connections on 550 board.. I used this rather than main battery connection as there was already way to many wires on it. It also serves as a bit of a fail safe.

Not sure what size the cable is... it's pretty beefy though (but same as battery wires)

I think two 8400mah would be way over weight

DJMK4 · 27 Jan 2015 at 14:25

Tonights jobs:

- Cut ends off lipo battery and solder on XT60 connector

- Cut ends of deans connector from IMAX B6 cable and solder on XT60 connector

- Connect some of the servo cables between X8R reciever to the NAZAv2

On NAZA v2 connect the following ports (A, E, T, R, U) to the appropriate channel on X8R

A: - Connect to Channel1 on X8R will map the channel to appropriate stick on TX
E: - Connect to Channel2 on X8R will map the channel to appropriate stick on TX
T: - Connect to Channel3 on X8R will map the channel to appropriate stick on TX
R: - Connect to Channel4 on X8R will map the channel to appropriate stick on TX
U: - Connect to Channel5 on X8R mapped to 3 way switch for flight modes

EDIT: Just checking youtube videos, so if you use S-BUS, you dont need to connect the individual reciever channels to the NAZA individual channels? its all done thorugh a single SBUS cable?

Maybe a few more bits but not sure yet

Just noticed the weight of the 4S I have is Pack Weight: 552g (is this too heavy for a F450?)

You only need one servo cable between X8R and Naza from memory. This is because it uses SBUS which simplifies it. The rest of the traditional channels (they become ch9-16) can be used for things like lights / video switches / gimbals etc etc.

All basic controls / and flight mode + IOC mode go through SBUS

You need to bind the X8R to your Taranis in Mode 4 D16.. (before you bind you have to put two jumpers on to make it do this)

Nah that's well within the weight limits for a 450, it won't be the most agile with the extra weight but it isn't bad by a long shot.

Yeah just read about the S-BUS and not having to use the other ports

The table slightly confuses me that you posted, will have to read further in to it

The mode you mentioned this will allow me to use Channel 1-6?

Flukester · 27 Jan 2015 at 14:48

The Mode 4(D16) gives 16 channels in total with telemetry. Ch1-8 are via SBUS to Naza and handle everything flight related. Then that gives you Ch9-16 on normal outputs for other things you want to add.

I posted photo of how the X8R must look before you bind
