Tarot 680 pro build, surely they'll a lot of questions!

[Flyin fisherman]

Green... That's me!!
Tarot 680 pro/naza v2. The power supply coming from the pmu... can I solder it to my board, the same place my main battery connects?

 

[Carapau]

You can indeed solder the leads from the PMU to the power distribution board. Just make sure the voltage from the main batteries is within the range of the PMU's input voltage. WKM and A2 will take up to 6s so I am guessing the the Naza will be the same although not owning I can't be sure so do check.

 

[Flyin fisherman]

Hey Carapau, thanks for the quick response
Yes it also supports a 2-6s lipo

My next question is, does it matter where on the board I solder it too? The + - from the pmu aren't very long, conjoining them with a + - for a motor might help with ease of installation if possible.

all, thanks for your time!

 

[Flyin fisherman]

Have the pmu power supply soldered on to the battery terminal for now. Going to post the parts going into this build. Probably going to have a lot of questions, any tips/suggestions/pointers are welcomed.

The quick release prop adapters I got changed to Match CW/CCW rotation. Not my first muiltirotor, it's my first one this size also my first build.

Having an issue calibrating ESC's, not sure this is normal. Powering 8ch Futaba receiver through my pmu for calibration. Receiver links with the 10j instantly, when I power up the board (testing without naza wired in) I get random ESC's beeping one short tone every 2 seconds and the motor makes a slight motion cooinsiding with the beep. I can calibrate them all one by one, all seem to calibrate properly, but that 2 second beeping doesn't stop. When I set up the naza and power the unit, I don't get the beeping but a constant flashing yellow light

Read a lot about the flashing yellow light, haven't tried to flash my ESC's. Any other advice?

Thanks all for your time and responses! Fly safe!

 

[Flyin fisherman]

Cancel that.... Figured it out!! Slowly but surely, learning a lot though

 

[Flyin fisherman]

Ok... Probably a silly question... Does it matter which side of my ESC I tape/ziptie down?

Thanks again for your time

Depends on the ESC, some of the larger ones have a heatsync and you either want that facing out for cooling, or if you have a vulcan type frame with aluminum arms, you can put the sync against the aluminum to assist in cooling.

I'm using.....
» 6 x Hobbywing Multi-Rotor ESC XRotor-40A [XR40A_V1]

Mounting them face down makes the build a little cleaner as I couldn't fit them under the motor mounts. Shouldn't be a problem then?

 

[SleepyC]

It shouldn’t be, but I always like to make sure the heatsyncs have air or aluminum to dispel heat. One side should be flatter than the other. The flatter side I consider the back and usually put that against carbon.

 

[Flyin fisherman]

Thanks sleepy, that's the side I was looking to tape down (the flat side) took it all apart last night after making sure everything was working. Time to start final assembly (thread lock and braided wire sleeves) having a little trouble finding a long enough m2.5 screw to mount the auto landing gear. The provided screws were 25 and 30 mm. Need a 35 mm and a lock nut. Aliexpress is the only place that has em (not hex head) Ordered all tarot parts thinking they'd be compatible.... Not the case

Thanks again for your time!!

 

[Flyin fisherman]

Hey all!!

What's the do's and don'ts for mounting your internal software? Can I mount my btu on the receiver, or my isod mini on my can bus?

Curious if they'll cause interference with each other, or over heat!! Any thoughts are welcome.

Thanks all, cheers!!

You guessed it!! Another question.... While hooked up to naza on my pc, in the basic tab, on the bottom its supposed to display your 3 modes alti/gps/manual (failsafe inbetween) I have alti twice and manual... Looking to take out manual for the time being and add GPS... Anyone know how?


As always, thank you!!

Hi fisherman, the thing about taking away your manual setting and just using gps and atti is you lose the ability to calibrate your gps by not being able to flick your mode switch rapidly 6-10 times between manual and gps.
Anyway, to answer your question you have to go into your radios servo travel adjustments and limit the switches travel so it never goes in to manual, you may even have to go into servo sub trims. I'm on a DX8 so different system but imagine it's kinda the same.

 

[Flyin fisherman]

Thanks for your response strike!! Been really busy with work lately. Slowly picking away at the build as I have time. Been making crappie jigs and repairing rods as well. Going to try and post a few pics... I really appreciate everyone's help.

How often in the field do you need to recalibrate your gps? I'll have a laptop out there, and will be able to hook up to the naza assistance if needed.

Been doing some research on batteries/naza voltage protection/C ratings... Trying to figure out the best way to push my flight times. Flown it a few times (testing the naza/flight times) nothing more then 10 ft off the ground lol. I have a 6c 5000mah 25c battery I purchased to test with, it's a storm battery from helipal.... I have no problem running 2 in parelel if need for maximum flight time. Since I'm #124 335 to build a 680 pro.... Any tips from the experienced crowd?

 

[Flyin fisherman]

Hey all, can't figure out how to post pics

What's the general concencess on running 2 3s 5200mah vs 1 4s 10000 mah?

 

[Flyin fisherman]

I only managed 8 mins on the 5000 6s I have (naza landed), was kinda disappointed with the flight time. Read some info on cold weather having negative affects on lipos... It's was -8 C when I tested it. Any help in the questions above is much appreciated cheers!!

 

[Flyin fisherman]

Hmmmm, no love?? I have a problem I could use some advice on from anyone else who built a 680 pro with auto retracts. When I mount the auto landing gear, using the provided M2.5 30 mm screws.... I only have 1-2 threads to screw on too. Trying to find 35 mm screws is seeming impossible.


Anyone else have the same issue?
