This video takes us through the installation of the motors onto the ESC/motor mounts, and attachment to the booms, and the soldering of the ESC wires to the PCB. I mention this in the video as an afterthought, but you could totally shorten the ESC wires to be more of a precise fit. I didn't, and it doesn't bother me. Those wires aren't visible once the final assembly is complete anyway.
The last thing of note is with regard to the right direction of the "front" of the PCB panel. I have decided that the side with the battery terminals should be the back on my build, since the camera gimbal will be up front. This works fine, but note that if you are planning on using a canopy, this will pose a problem, since Tarot designed it with the battery terminals in the FRONT. Strange, I know. It's not a problem if you do it either way, but if you want the canopy, you should do it opposite of what I did, or just know that the RED is in the back instead of the front (which is also something I thought hard about).
Anyway...thanks for watching.
Your medical tool is a hemostat - I use them too, for soldering, and fishing, and lots of things... very cheap at any fishing store.
Fine presentation, thanks. I hoped to see clearly how your motors are fastened to the carbon fiber plate. The screws supplied with mine are so long they almost touch stator wires inside the motor. Is it a good practice to use spacers between motor base and carbon fiber plate? I find 3 4-40 nylon washers is optimum. Not sure nylon is the right material.
how did you checked the direction of the motors without having the flight controller installed? Is there a "manual" way to check the direction of a brushless motor, and thus if the wiring is correct? Thanks, keep up the good work!
Hey man great vids_:)
How much didi the entire build cost?
Tnx

Hi CPO, you state at the end of your video that if someone is going to use a canopy it will be a problem if soldered the battery lead from the back. why is this? Isn't it the same thing ? if im correct the canopy need 3 bolts
Sorry ...
What did you use to power the ESC and motors a 14 AWG or 12 AWG?
Thank you
I solved it myself ... well I checked all the movies and then I found a frame where you can see perfectly well that are 14 AWG.
Thanks anyway
cant we just run the battery wires through the center of the 2 plates towards the back and have the wires coming out there?
Hwo do I put the dji naza v2 on it??
Hello! What about the flight time?
Isn't XT 60 a little on the low side? I guess 10Amp per motor wont be out of the ordinary which would bring you close to the rated Amps of the connector.
Good eye. The real answer is, probably so. I haven't sorted out the power system completely yet (don't even have flight batteries yet) so I am not that far. the XT60 battery connection is a temp solution to get me to the point that I can plug in my Pixhawk and 4S battery (which as you can see from the next video I am about to post) is a tiny little fella I have for DTF planes. : ) I was hoping to put it on the watt meter soon to see how many amps it really draws with/without props. Either way, I don't have my permanent battery solution yet. The XT60 is temp.
EVERYTHING cpo
The XT60 connectors are incredible, I've seen them on 700 size helis which draw over a hundred amps with no problem without getting warm. You're fine using XT60, they are awesome connectors.
what exactly is a cold joint?
A cold joint is a bad thing. It's basically a solder connection that hasn't completely melted together to form one single bond, or has some impurities. If you move a solder connection while it is cooling, it sometimes can cause a disruption in the joint that will result in unreliability. It may work fine...and then randomly cut out. That's the usual symptom of a cold joint.
Connecting power cable ends to the board seems really iffy.... if they come apart in flight ur screwed
Agree
Why would a soldered cable come apart as apposed to any other location of connection. I have never seen a wire soldered to a board just unsolder itself.
I'm a little confused. In your Max Amp video you recorded an average of 17 amps with a 20 amp burst. Why wouldn't XT60 be ok for this application then? Or is that figure per motor?
"While my results leave me with a 17A constant at full throttle and a 20A burst, the reality is that my actual flight levels will be much lower. In fact, at half throttle, I was only pulling around 5A -- that's a 30A total draw at half throttle!."
Sorry to confuse. Yes. the 17a max average is per motor. When running all 6 motors at max throttle, my power system will see 102 amps max (17x6). That is the constant at maximum throttle - but is more than the XT60s are rated for. Then my later comment is to state that since we really don't fly around at full throttle with these (not like helicopters or speed rigs) your actual flight averages are going to be actually way lower...which is why many people have no problems running with XT60s. The potential is there to pull way too many amps for the XT60, but most time in flight is at the safe levels. I hope that helps. I still feel good about my decision to use EC5s, but I can also see why people say the XT60s are just fine.

Cool thanks for the clarification! Guess at some point i'll have to make the jump to another connector capable of at least 120 amp, have you had any other thoughts on what you might do?
Tama Enright Just check the connector after you finish flying, and make sure it is not overly hot...but you should be fine. I am leaving the EC5s on mine, as they are rated for 120A continuous. More than enough.
EVERYTHING cpo Thanks again....great build videos BTW! Looking forward to the next in the series, especially keen to see where you mounted Rx and the Pixhawk!
Here's a teaser pic I posted on RCGRoups a little while ago. You can see where I have everything mounted.

I'll get caught up on the videos soon tho!
