I have a 3 cell and its still around 11V.
Its still charged up, I think.

The motor would occasionally start and run OK but then the jitters would start and finally...smoke. I bought a Scorpion ESC for , the Rimfire and no problems, ran like a champ.

So to add to what TJ said, I too have never had an HK motor fail (SK2 in my case) but I have had a Plush ESC fail.

On the HK returns, I have had no issues. I have returned several items including a Blue Series ESC that was DOA and a Compact Lipo that would not balance. I emailed them, got an RMA and was able to return these two to the USA warehouse even though they were purchased from China. Total turn around was about five days.

BTW - a very experienced friend bought 6 Turnigy Type TY-P1 and 4 of them smoked within 30 seconds of start up. Don't buy them!

Good luck!

I don't know exactly what you meant by a "power spider".
If it's what I suspect, you butt-soldered several wires together to form a "spokes on a wheel" type thing.
I'm not questioning your soldering skills, but since you were going to do this anyway...
Desolder your ESCs from the "power spider" and set then up to test and run the motors and ESCs separately.
See what you get...


Another point of advice from someone old enough to be your grandfather....
You've been at this all day.
Your nerves (even though they are young) are probably frazzled.
Give this thing a rest.
It will be waiting on you tomorrow, and things might look much different in the light of a new day...
Thank you for that advice! My parents told me to stop too... give it a break and come at it again. One tip I've seen on this forum is "know when to walk away!"

I've just tested taking out a working motor without one of the bullet connectors attached, and I had the same issue. I'm positive now that somewhere between my ESCs and my Motors, there are quite a few bad connections. I plan on just getting rid of all these bullet connectors and splicing the wires directly to the ESCs

G;day all,

very interesting last page of posts, especially T.J.'s comments on motors.

Having read completely through this thread twice I'm under the impression the DJI NAZA is somewhat selective on what aftermarket ESC's are used, but almost does not care what aftermarket motors are used, is that a correct assumption, or did I miss it completely?

Thanks

One issue I ran into with my first quad build: The wire going into the bullet connector from the motor sometimes breaks off!
You wont know it because of the shrink wrap.
You can test this with a multi testor and wiggle the wire or just feel it around the base of the bullet connector. The same can happen with a cold solder joint you made.
Those are the cheapest and fasted ways to test.

I had 3 of them (all on different motors) happen during the build processes and it was easy to fix. Just remember to re-shrink tube it.

Naza talks to the ESCs, the ESCs talks to the motors. The Naza doesn't really know what is spinning the propeller... it just tells the ESC to make it spin faster or slower to keep level.

Naza needs fast ESCs but doesnt care about the motors.

Fixing is where you learn though.

If everything came too easy, it wouldn't be fun

If you don't lose your mindset, you are going to be very successful with this hobby.
(And, probably, life...)

Hey Gary
I really like them a lot. They draw about 4 more amps than my 10x5 Graupners but they do provide some noticeable extra thrust. They are stiff like the groupners so nice steady video with my GoPros.
