Blackjack 29 Blown Motor

[olwarbirds]

Amen ... enjoy and im glad to hear that your happy with the CS on this issue... Just to clarify ...it wasnt PB who said that the esc was only 6S rated it was CS dealer rep at HH ... I will keep yall advised on what results I get with this.... all the best ... DJ

Proboat has done the same thing Traxxas did with the spartan. That's just not a good reliable 6s set up. Especially for sport running. Even if you do get it running reliably the hull has a tendency to stuff badly at high speeds. I love my first gen but know its limitations.
How many times will they replace the boat because if failed on 6s which it will again

Stadium,

You are correct the stock setup is not suitable for 6S configuration w/o mods and if you are lucky and motor do not burn, then it won't be for long.

[gyrotron]

I have two of these motors, I am interested to know how you like it, have not tried mine yet, thanks.

Loves6S,

Definetly give this motor a try with either the Miss Geico or the Blackjack 29. I think you won't be dissapointed.

Guys,

Report from the pond on the Turnigy SK3 EDF-3659-1900kv. For $47.88 this motor is a steal if its quality is as good as its power performance so far. The boat had better acceleration with the x440 /3 than it had with the stock motor; the added 100kv of this motor really gave some punch to the prop acceleration which I liked. Speedwise it was faster than the stock using a 4S setup and when I opened up the throtle it was lightning fast; much faster than the stock and still controlable. Temps as follows: Motor 101F, Batteries 86F, ESC 95F. Now on 6S this boat screams with this motor and I could not open it up full throtle w/o flying the hull; almost uncontrolable at full throtle. Temps as follows: Motor 111F, Batteries 94F, ESC 102F. At the moment I don't have a GPS to testify on the actual speed for the two cell counts I tested.

Conclusions so far: The Turnigy SKE EDF motor is a great upgrade if its quality holds up to its power (quality is yet to be determined). In terms of acceleration; this motor works very well with the x440 /3 prop. To me, this setup is great for added speed and acceleration running on 4S w/o compromising the stock ESC operation. I really like this setup on 4S and I will be running it from now on; I felt comfortable with the temp reads and initial acceleration and speed exceeded my expectations with a 4S cell count.

Currently charging my (2) 2S pack for a later run after the football game...

Proboat is a well known, and well respected company for making great boats. I dont think much testing was done on quality control when putting out the Blackjack 29. It clearly states on the box and in the manual, it can run on 6s, everyone can see it. Even my local HS said it was ok. Running a boat on 6s clearly needs beefy wiring, connectors, and atleast a 120 amp esc to be safe. And 1800 kv on 6s is just asking for trouble. I am almost finished rebuilding mine and will post pix later today. Anyone wishing to run this boat on 6s from factory should swap the motor for a 1500 kv. The factory 80 amp esc should handle that.

brg65,

What seems interesting/suspicious to me is that eventhough the release of the Bakcjack was delayed a lot, PB did not do the appropriate testing QC?, maybe they found this issue and had to delay the production while trying to find a solution/workaround. It's just my gut feeling on the issue.

Looking F ward to see some clips of that motor in action gyrotron. I have the Geico, and I have both a leo 2000 and a 2150 kv motor and on 4 s it's both fun and controllable.I cant imagen how the bj 29 is on 6s, fast as hell :-)
I have my friends mystic also in the house and have driven that a few times, and it heaps better than my geico, runs better and much more easy to dial in, and get bounch free.

Us running a stock BJ 29 on 6S.....it handles great...as does the impulse on the same setup...we use 2 11.1v 5000mah 40c CRC lipos

upgrades to my Blackjack 29

[gyrotron]

brg65,

That is a high end upgrade compaired to what I did. I went on a budget for my dead Blackjack. I am looking preferibly for a camerawoman to make a video of the boat running the Turnigy SK3 EDF.

Nice setup you got there!

[gyrotron]

Max,

Very nice runs. Where do you boat?

Jim,

I was using the x440 /3 prop which I ran before on a 4s count.

prop down.

GYROTRON,
I am curious for my own knowledge, did you actually hear a "pop" and can you still turn the motor shaft? I want to know if the rotor disintergrated. It is odd to me that the motor should give out before the ESC. I have several ProBoat branded motors , they seemd to be really well made, although I never tried the 1800kv with 6s. I am very found of them, both the 1500kv & 1800kv.
Now I don't want to say anything w/o personal experience, but when the current crop of boats came out sporting the "Dynamite" brand, I was not particularly jumping with joy. I had some Dynamite branded motors and ESCs for cars and my impression was they weren't first tier stuff. But I thought my concern was unfounded since I read from one post here stating that they are the same things just marked under a different brand/label.
Therefore I want to know had this been an old Proboat 1800kv motor , would it have lasted longer?

Doby,

What three blade prop would you recommend?

Thx

tlandauer,

Yes I did hear a pop before the boat stalled in the middle of the pond and the rotor is unable to turn.

Thanks for your reply! I hope you get your replacement soon, and also thanks for letting us know the other motor, always good to learn!
Looking at the picture I wonder if the RPM increase from 6s disintergrated the rotor and locked the motor. Although that would have cooked the ESC, hopefully someone else might explain this further. I had an out runner burnt once because it got tangled up with water cooling tubes, the wire coating was blistered and turned into black soot! After it cooled down I could still run it! ---Of course I changed it right away but it was still able to turn! ( be powered ) It takes alot to burn a motor.
