Blackjack 55 electric build?

[blowNover]

Looking at buying a blackjack 55 hull and building it around a leopard 4092. Just looking for some advise. I already have the motor. So is it enough should I get a second and run is as a twin. And what kind of speeds might I be looking at run as a single and a twin. Any input is good input. Thanks guys.

Do it as a twin. Or go up to a 56mm motor for a single. That 4092 would work, but man that motor and esc would hate you

What kind of speed would I be looking at with just the one 4092 you think?

Oh and if anyone has a blackjack 55 or similar size cat hull the are willing to part with please let me know. Maybe even a larger mono if the price is right!

I dont think a 4092 would work thats a big hull..I have the old 55in. shockwave..Someone just did an article in the new rc boat mag. on the 55in. blackjack..

I'd do some research to find out if that hull can handle speeds over 40mph. I know the smaller blackjack doesn't corner very well. I built one for a customer who bought it off ebay and didn't know what he was getting, it was junk. I cleaned it up and dialed in as much as I could with what parts he had and it did not turn out well at all. Search youtube for blackjack55 FE

What kv is that 4092 ?

[blowNover]

I have the 1730kv 3d. And I know the blackjack aren't great in the turns I have a modded brushless 26. What hull would be a good build for that motor or two of them then?

[Jason4636]

I have a single 4092 fantasm, that has hit 70mph. But if I had it to over again I would made it a twin.

[mtbenjamin77]

If you want something reasonably priced with minimal building I would get the zonda cat and put twin 4092's 1730kv. It's 41" long which is a good size boat. I'm building a custom zonda right now with twin 4074s which I think will be under powered.

[Jason4636]

Fantasm and zonda are the same boat. I'm not sure if twin 4092 will fit. The best guy to ask is Keith Bradley. He has probably built more twin fantasms than anyone.

I would sell it and buy 4074 2000kv motors for 6s. Idk the speeds you're looking to reach but the boat will run 80mph with setup I listed. If you want a boat that runs 65 mph go leopard 4074 1600kv and it will be very reliable. I understand you have the leo 4092 but that motor would sell in a matter of hours in the buy n' sell section of this site. Of course your decision but twin 4092 will just be overkill in the boat.

[mtbenjamin77]

twin 4092 will just be overkill in the boat.

Or make a very reliable 80 mph setup

On 5s with those motors the boat is really moving I believe they're only like 3674 motors.

Overkill in what boat? He asked about the blackjack 55 right?
