Blackjack 29 Blown Motor

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.

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.

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

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.

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.

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) .

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.
