Blackjack 29 Blown Motor

[LOVE6S]

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 screas and I could not open it up full throtle w/o flying the hull; almost uncontrolable at full thotle. 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...

Thanks for the input on the motor, I had a good feeling about these motors, they are actually a EDF motor or jet motor and sposed to have some good bearings, I wonder if you went to a X440 2 blade prop if the boat would be a little better on 6s, is it just blowing over at top speed, because of the weight and lenght of the hull? So all you changed is the motor and the connectors, the esc and wires are holding up ok? Looks like the temps are good, I think the open motor front helps too. I love this boat, just wish it was a couple inches longer, nice job on the fix, looks like it never happened.

...nice job on the fix, looks like it never happened.

Yes I took the time to clean it up well; vacuum the interior a couple of times; three passes with kitchen/desinfecting cleaner wipes, and some alcohol rub over the wire's silicone at the end to release/eliminate the burnt odor.

Nice, lm looking forward to updates on that new setup you have guy...im looking at options for our BJ29 and Impulse31.... DJ

[Doby]

Doby,

What three blade prop would you recommend?

Thx

Smaller..... If you ran the same prop on 4S as you did on 6S, there's your problem, and it sounds like thats what you did.....Also, running for 2.5 minutes before brining it in for temp checks after you switched from 4S to 6S is not the brightest thing to do either....30 -40 seconds max with a new set up should be the max before you bring it back for a check. Its a combination of both your's and ProBoats fault as to why this happened. ProBoat should not advertise 6S unless they also tell people to make other changes as well before running 6S..

As for prop choice...again, smaller (there is no such thing as to small to start with) and bring it in often...check temps...slowly prop up....repeat...

Doby,

We are here to enjoy, share and help each other... not knowing something or having less experience than others is not IQ dependent... nonetheless I thank you for the info on your post.

Gyrotron,
Sorry to bother you again, I really like that shiny water cooler jacket, where did you get it?

[maxmekker]

Max,

Very nice runs. Where do you boat?

I and my friend run in Norway.

I sat up his PNP Mystic with a T180 stock motor and a Prather 220 prop. And boy did that run well. Good run times and nice speed with the stock motor, and the boat was just running so smooth.
The M and BJ29 only differs on the esc ? Motor is the same.I Still have that stock 1800 Mystic motor , it was only run one time in the video before it got swopped for the Leo.



I smoked my pb 1500 kv in my geico, but that was on 5s and prather 230, holy smoke that was fun while it lasted. It would turn but the wires were almost gone...
On 6s with the prather 215 I had no problems, strong motor , nice temps.

[maxmekker]

Here is the last run we did . To cold and dark here In Norway to do boating just now I'm afraid, so make and keep those video clip's comming so we can have something to watch :-)

Here my friend dared to open up some more . It's pritty fast with the setup now. 2150 kv leo 642 and nano 65-130c lipos.

I got the jacket from the OSE shop online

Thanks, I saw it now. Looks much better in your boat than it is on the web.

I will try an X438 prop this weekend and report about the boat handling the 1900 kv and the 6S count. Have you tried the SK3 motor?

I have nut has a chance yet, been working on some bigger stuff. is that x438 a 2 or 3 blade prop?

[Jason4636]

I hate anytime I have to go retive a boat. Say it flips, burnt motor, esc, or anything. But to me you guys that are running 6s with a 1800kv motor. Keep your rescue boat handy!!! I always like to be on the safe side on my setups. I try not to ever run higher than 30-35,000 rpm. And you guys are running 6s with an 1800kv motor, thats 39,960rpms. That rpm is up their in SAW rpm range to me. To keep it from burning up, prop way down. But then you don't get the benifit for running 6s. Or get you a MG 1500kv motor and run 6s. Your still turning 33,300.
Or do like I did with my MG. Buy you a leo 4082 2200kv, T-180, x642 and run 4s2p. And you'll run in the low to mid 50's. I still have some tuning to do on mine. But I'm sure, I can get it into the mid to high 50's

With the exact same set up as yours my MG ran 53.3 mph on Garmin GPS.
I understand everyone is different, but personally I also enjoy the knowledge of having a comfort zone. That said, the Proboat 1500kv really CAN handle 6s.

[Jason4636]

I think a 1500kv motor is safe running on 6s.

I know in my fantasm, I have a 980kv run on 8-10s. Thats only 29,000-36,260 rpm. And I just smoked a $300 esc 2 weeks ago. And I'm still not anywhere near the rpm's there running. Now I can't wait to build my MHZ Mystic mono with twin Proteus 524's. It should haul some a**!!!

[tlandauer]

That sounds awsome, can't wait to see your build!

BTW, on my DF 45" Sniper , my Neu 2230 1y is 725kv running 12s 2p, and that is only 32625 rpm. I should clarify that I DID NOT build that boat, bought here from a member.

[Jason4636]

What speed are you getting with your sniper? I started out wanting to build one of them with a single proteus. But I'm really leaning toward a twin mystic mono. I might have Keith Bradley build it for me. He built my Fantasm and it's top notch. At $650 just for the Hull, and that's not including shipping from Germany. I'd realy hate to mess it up.

[tlandauer]

There was a youtube link from that member and he had reached 70mph. ( I can't find it now, but it looked real fast) , I ran that boat for a very short time after I restored the hull from shipping damage, I did not clock it with a GPS. Because it is rather on the big side and I have not thought of running the boat often. It has a Shulze 40-160 ESC which I now really appreciate its smooth throttle curve now that I have been in this hobby a bit longer. In the end, you really do get what you paid for. lol...
I think whatever decision you make you will be happy with the boat, I understand your concerns. Nevertheless, it is exciting and I wish you the best !
Cheers!

Here are some pics of the clean up and new motor I will be testing on the burnt Blackjack while the replacement boat arrives. I picked up ad Turnigy SK3 EDF-3659-1900kv ($47.88), installed 6mm bullet connectors, removed the sticker and added a water jacket. Motor started fine on dry so I am guessing the ESC and electronics are fine too. I will give it a run tomorrow on 4S and 6S and report back about this motor.

You should run a smaller prop. and definitely not 6S with the 1900kv motor it will fail

It is a x438 2 blade

mtbenjamin77,

I am definetly running this motor (Turnigy SK3 EDF - 1900Kv) with a 4s count.

[gyrotron]

Hi Gang,

I just finished replacing the stock motor and ESC on the Blackjack I received as a replacement. I had a Feigao 540XL 10T 1,668 Kv laying around and went ahead and installed it together with a Seaking 180A. I will be running the boat with an X440 /3 prop today. I will do the first run on 4s and the second on 6S. Here are the pics.

[Diesel6401]

A few of us had a feeling this would happen. The Traxxas 6s marketing from PB/HH rather disappointed me. Have a look at the Obsession w/ 6s thread in the battery section. The PB1500 would have been PERFECT for this 6s route, I'm not sure why they didn't go that route. That motor has been proven on 6s. The 1800kv pulled around 60 amps on 4s w/ grim 40x52/3 which is similar to x440/3 on my MG. Not sure how different the new revised motor is over the old Stiletto motor, but I would imagine identical numbers. I can only imagine his many amps the motor is pulling on 6s with the same prop around 40K unloaded. I would highly suggest folks NOT running that motor on 6s. Im not sure how the new esc performs, but the PB1500 with the new esc and guys could have a nice 4s-6s setup... just my 2 pennies....

Yeah I said the same thing.... Why would those meatheads at proboat not have put the 1500 in there? It appears they have no idea wtf is going on....

[stadiumyamaha]

Hear hear.

[tlandauer]

Love that 1500kv motor, I also dig the 1800 on 4s, they both have given me reliable services. I know many have said the Dynamite motor is the same, wonder if it is really the case?
I am afraid Proboat has succumbed to marketing gimmicks: the higher the cell count the more the sales boy at your LHS can brag about it. I was at my LHS about a year ago and a guy was buying a Spartan, this is already the V2, he had some concerns about running on 6s, the sales boy was telling him go for the 6s, it will put a big grin on his face.
Hopefully they will have the integrity to revise their sales literature in the future. ( Too many warranty replacements will do that) .

[dana]

Yup

How did you fix the T180 to the hull? Here is my mods. It's a OSE Leopard 1400kv with the T180. The 1400kv should be safe on 6S.

Hello lomdel,

In my case, I carefully drilled a couple of holes on the hull's electronics tray, both sides of the ESC location and used a zipitie to fasten it down.
