Testing A Few Propellers Blackjack 24

[@imbranjamil4994]

Wow amazing

[@chadallen4910]

Hey IC...I ended up with a Leopard 3660 / 2550 kv motor. Is a 90 amp ESC too small to handle that? What amp ESC would you recommend for that motor?

[@IRONCLADRC]

if you wanna play it safe go with the 120 fly color or 150 ose.

[@IRONCLADRC]

Hobbywing 120 pro would be a great speed control for that motor it has turbo functions

[@chadallen4910]

@@IRONCLADRC you da man thanks

[@nealstarling5422]

Awesome, I have a blackjack 24, it’s been my goal to surpass 50mph, its come down to the prop and I think that TFL “hey big blades I know your the one” (she said). Again another informative and entertaining video! Thanks

[@PigglyWigglyDeluxe]

I’ve got mine to 65 it’s wild

[@leddiablo101]

Love seeing the Blackjack rip! Hoping to get mine that fast 😂

[@roadstar499]

I have many carbon Graupner props many are still in bags... so what does 42mm and 59 mm pitch mean pitch wise?... you say just 42mm 4 pitch when explaining so i am lost on pitch on mine saying 59mm ... do you have a video explaining the difference?...thanks

[@IRONCLADRC]

Most props are measured differently from company to company Grouper measures there pitch in inches potentially traveled with one revolution of the prop..... diameter (in) x pitch = inches traveled. Ex. Prop 4214 Hopefully this helps? Hopefully I'm correct?

[@roadstar499]

@@IRONCLADRC thanks but do you have any idea if a 4 pitch is less or more than the same 42 with 59mm pitch... if not no big deal... i usually just look at props and compare than try them for a minute and check temps... i have cooked a lot of parts in the past.but now i do everything in baby steps when switching props.... thanks for all the great information

[@vadimkvak1751]

Big B , what would be your setup for 52" cat? Both electronics and prop/props

[@IRONCLADRC]

Brother I wouldn't even know where to start with a boat that size.

[@adamjones9775]

I ordered my first OSE CNC prop today. Started with the 42mm, I hope I didnt buy to big of a prop for my BJ24. Im gonna have to look more into the TFL props. Thanks for the awesome guidance once again. BOAT GANG!

[@IRONCLADRC]

42 is about the biggest prop I've run on my black jack. You'll love it

[@paul340mopar]

Man you got a lotta Props!🚤

[@IRONCLADRC]

I like little props and I just can't lie. Lol 😆

[@55steviegreene]

Which type of prop keep the boat planted in the water

[@IRONCLADRC]

Personally I like the 438 with proper weight distribution & the octura m440 with proper strut & weight positioning

[@marknickells6097]

ADDING. THE CNC .440 mm, rides real nice on that boat. But, I also run , a 120 Amp . Dynamite controller. The Stock ESC, strut, and FLEX should be updated . Also add the Heavier flex cable upgrade, and go with the V 2 version, of the strut and rudder assembly. IT has better fittings , and the prop has clearance , doesn't vibrate , like the original version .

[@aytonn1749]

Hey man I bought a propeller 438 and I thing I bought a wrong one, it doesn't fit the shaft, are you using the stock size shaft? I am all stock, could you give me the a part number please?

[@IRONCLADRC]

It should fit like a glove? How does it not fit? Is the shaft to big? Or does the prop not fit the drive dog? 🤔 let me know I'll try to walk you through the fix

[@aytonn1749]

@@IRONCLADRC im sure i bought the wrong one. 4mm P1.4 , 40mm. But even it's a 40mm the 4mm should of fit the shaft, right?

[@jaycevessier7554]

That 3 blade in a 44 mm is insane on the blackjack 42

[@paulwindom4647]

Hey Iron clad I've been watching a ton of your videos on the BJ24 and Veles, Curious if you tried the BJ24 with the stock motor on 4S and if you have a prop you could recommend?

[@IRONCLADRC]

Yes, the stock blackjack 24 motor will handle 4s, I ran a tfl 438 &440 with great success, octura 4214 is another good one

[@paulwindom4647]

@@IRONCLADRC Thanks your the man fun getting back into this after the supervee days may be in touch some more! Appreciate your stuff and you have a new sub!

[@aytonn1749]

Hello, man I just got my first boat, a black jack 24, any good advice for beginners ?

[@IRONCLADRC]

Checking all your screws Grease the flex cable before each run, add foam to the hatch because the hatch will come off occasionally, sharpened & balanced tfl 438 prop is a great cheap upgrade prop for this boat.. have fun.

[@aytonn1749]

@@IRONCLADRC I really appreciate the info. I probably will be contacting you in the future for more question, if that ok? By the way I enjoy your videos. Where can I order the prop?

[@noahbailey4220]

Is that a homemade propeller box ?

[@nealstarling5422]

I’m sticking with 4s just as a challenge, looks like Big B beat me to the punch but with even a smaller motor than my 3674 Some info on strut angle could help as well, I run mine pretty much like a mono hull. Thanks

[@IRONCLADRC]

I like the challenge aswell I've had 6s in the boat several times with different 6s capable motors, hand down enjoy the boat more on 4s like you said it's a challenge to get the highest possible speed on 4s. The boat handles better light weight.

[@marknickells6097]

Adding to Mix. CNC Detounged .440, sharpened and balanced. She's a sleeper, and hitting open water. Holy crap on 3 S. I'm afraid to try it on 4 S. It practical flew. The only thing that caught my attention, was the electronics were a bit hotter, so I am concerned about running a .442. Too much prop? Opions ? I've run a smaller Grim Racer, and a TFL , ,38 mm. hi -pitch. It would be a little wicked ride, on 4S. I don't how you guys have kept a 2.5 Lbs, boat to stay on the water on 6S? I'm not that ambitious. But love the videos. Keep em' coming!

[@PigglyWigglyDeluxe]

My BJ24 is hysterical. I run mine on 6S with a dynamite 120 amp and Spektrum 3200kv motor and stock Sonic Wake prop. 65mph all day long

[@IRONCLADRC]

That's awsome

[@kylepietrowski530]

Miguel Flores :Did you have to modify rudder for the sonic wake prop to fit?

[@sebastianobeltrami8742]

Hi man Sebastiano from Italy here. Please can you please give me info about set up of throttle trim and throttle dual rate of Blackjack ? Another great video with this little beast. Thanks man

Bro, a glass top! What better conditions to try out props on a cat? Awesome stuff 👏 👌 I found this really useful Big B..Thanks for sharing with us 😀

[@IRONCLADRC]

Sure thing brother

[@marknickells6097]

What if, you used an AIR Dam, and Blue Printed the Sponons? It, may stay down better. ? Just a thought?

[@IRONCLADRC]

I've blueprinted the sponsons I hit 73 the other day on 4s.
