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,

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?

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**!!!
