Blackjack 55 coversion to electric

[Blackjack-sven]

Seeing as Proboat decided to send me a new hull for the one that's broken, I figure it would be fun to turn the one hull into an electric 55, but I have no idea what type of hardware and electronics to use or where to get it from. I was thinking of making it a twin engine twin inline strut rudder system. Does anyone know where to get this equipment from?

You will be fine with the stock hardware.
Might look into the upgraded rudders by Aeromarine.

that is one heavy boat, gonna need 2 big motors since you plan on running a dual set up.
Look forward to spending some serious money on batteries if you havent already done so.


Cant wait to see it moving.

Hope you have $$$$$$$$$$$$$$$$. You are going to need it to do a single motor conversion, let alone a dual!!!
Siplest methoud, order the stock hardware from Horizon, or transfere you existing hardware. Use a single motor, a 3080 LMT or the big Neu, get 4 packs of 5S LiPos and a 240 HV Hydra or a Schultze speed controller, Figure about $3,000 as an estimate!

[Blackjack-sven]

I think I'll go with 2 3080 LMT air cooled motors ($1200.00) and then add water cooling jackets (40.00) around them. I'll pick up 2 Hydra 240 HV's (1080.00) as I only have one regular 240. But where will I get the batteries from? What voltage and amperage would I be looking for? Would the MaxAmps 12000mah lipo's work?

So far my bill would be $2320.00 without batteries.

[Doby]

Minuimun Qty 4 , 5S LiPos of at least 5000mAh 25C rating. Connect in series and then parallel. If you are going with twin motors, figure about 3-4 minutes run time. As with any LiPo, get the higest capacity and C rating possible.

[txboatpilot]

If you go with twins you will need 10s2p per side.. That is a total of 8x 5s 5000mAh 25/35C packs to get it done right.. You need 37V/10,000mah + per motor and esc...

[Blackjack-sven]

The best battery I've found so far is this

Battery: 10S-5000
Volts: 37.0
Max Cont Dischrg: 25C
Max Burst Dischrg: 40C
Max Cont Current: 125A
Max Burst Current: 200A
grm: 1250
Dimensions: L x W x H: 170 x 48 x 89

Does anyone know of a better battery?

[txboatpilot]

Look at rclipos.com,,, They have a sale on PolyRC 10s 5000mAh 25c packs,, You will need 4 total..

Rich, would you not need 8 to do the setup described in your post #6?

Nevermind:doh::doh: Just realized you were talking about 10S packs!

Name or somethng would be helpful:confused2:

[eboat]

A 10S lipo battery is going to take a good charger to charge and balance and if you have 4 lipos you will need 4 chargers too so you can spend an hour charging again to run less than 10 minutes

I do not think you will just be able to pop the hood on the car and charge off the car battery either

Sorry but there seems to be no name for this battery, but this is where I got the info from. Check it out.

John, this could be interesting.

I wanted to do a Brushless conversion on my BJ55 a while back and was told that One Lehner 3080, One Schultz speedo (this was before the Hydra 240 HV was available from Castle) on 10s lipo would get this boat hauling a$$. I gathered this info from RCuinvierse a few years ago, you could probably still find the thread on there and that may be of help as well. Twin setup?? WOW!! Better do some hull reinforcing, the glass on the BJ is pretty thin.

With the problems I've had so far with Proboats vehicles that was one of the first things I was going to do. lol

I was going to separate the hull at the joining point and build the structure as I did with the Dumas hotshot 7.5. Then install all the components and fill the rest with foam.

[kevinlew211]

Im not try to pop your baloon but, to me that hull is not design for high speed, my friend owned one and i seem its run so many time, its ok for straight away but not turning even with stock 260 running about 48mph and its ....... can't turn or you will flip, i thought you already know that, you will looking for 65+ with twin 3080.....at least, so dont waising your money and time on that hull, get something can handle that kind of speed, since you already paid too much for motors, escs....etc, the good hull is just like another dime to you.

[Blackjack-sven]

What 6 foot plus hulls are out there that are of good quality to do up electrically? And what should I do with the other hull then?

sell it to another BJ guy and buy an HPR cat like the one in my avatar :smile:

[Blackjack-sven]

Check out this boat.

Looks very similar to the blackjack 55 and it's running double LMT 2280's with 60s. Nice ride.

I also found this one. An HPR233 running on 2 3060 LMT's. Also very nice.

what you see is Jim Vaugh from my HOTMBC club Aeromarine Avenger hull, compare that hull and BJ55 is like black and white, i already setup 2 hpr, they both running great and handling is perfect, you can find my video here somewhere, search for HPR07 and HPR06, or you can click back to that video and search by that youtube member (Houstondominan) my video also under his name, we in the same club.

I can tell you from a gas boater's point of view the Black Jack does not stand a chance against several cats. Gas boaters would not dare put any bucks in that hull. The hull simply will not work under the power of a good engine like the quickdraw. Man if I wanted to spend the kind of bucks you intend to there are a bunch of european boats that will get the job done much better, made of much better materials and be of much better quality workmanship. The Black Jack was meant to be an entry level large gas cat made for low speeds and stock engines.

I'm looking at the "Flying Cat" from RCMK but was wondering if anyone ever heard of this company before or seen any of their boats before? If so what is their quality like? I'm assuming either way it'll be better than the Blackjack right? especially since it has a carbon fiber reinforced hull?

Their gas engines are top shelf all the way. I have sold every zenoah I have and converted to the rcmk 25.4 engines. GREAT workmanship.

[hookedup]

And what should I do with the other hull then?

do like DIEGOBOY and give it away as a freebe!!:lol::lol::lol::lol::lol::lol:

LMFAO......I'll get right on that. :roflol:

[kevinlew211]

Rcmk's Flying Cat is just over 34", either one Neu 1527 or Lehner 2280 on 6s2p will do the job, incase you want to go big why not Aeromarine Avenger pro 42" cat

I like going big but I think I like the sleeker design and looks of the Flying Cat. HPR's 06 looks real nice as well though. Might end up with that in the end.

you should think about RCMK Hydrolift as well, same dimention of Hpr115 and the price a lil bit cheaper overall, its come with complete setup, strut, rudders, even decal and detailing parts for $1000 i gguess.
