Rc Boat Bitz Trim Tabs for the Blackjack 42 GAME CHANGER

[@michaelpolitz9581]

I have been rebuilding an rc catamaran boat my dad and I built in 1988. Gutted it, glassed it, and hopeful it will be getting test ran in the next month or so. It's going to be over-powered, and it's only 28" so I was going to add tabs to help tune it and keep it on the water better. Your videos have been so helpful with everything from learning new electronics, boat setups, and motors. Excellent content! Thanks Big B!

I pick up a blackjack 42 two years ago and I am just putting it in the water. I am actually having fun with the thing

[@georgegonzalez9281]

Your videos don't need to go a particular direction every time. When Big "B" has fun, we have fun! As I watch this video, I'm finishing up a build on a 800mm all wood catamaran boat I bought from a China vendor on eBay. It's unbranded and the instructions are terrible but I managed to complete the hull with a lot of trial and error. The boat is awesome, but it ended up with warped sponsons. I've sanded the sponsons down and got rid of most of the warp, but I don't have anymore material to sand without risking weakening the hull. I think I'm going to need to make new ride pads and then blueprint the hull. I'm going to have to search through your library for a video on blueprinting sponsons. I love working on a boat project while watching KZbin - of course your channel is always first on the list. Peace brother!

[@IRONCLADRC]

I really don't have any proper blueprinting tutorials, the only hull I did for youtube is the blackjack 42 & at the time it was an experimental process. Unfortunately i didn't record the blackjack 24 blueprinting process 😕 wish I could be more help brother

[@topgun5399]

I just bought a used blackjack with those same tabs and looks like it does the job. Nice and even hull. Have it on my m41 and runs like a dream just run them parallel with the hull and it will run really smooth. Plan on doing this on the blackjack.

[@georgem.6136]

Rippin! They made a huge difference, to bad you didnt have more room, would have liked to see how fast it ripped with the batteries moved back

[@IRONCLADRC]

Next run I will take her to the river

[@marxboatworx]

Congrats on hitting 4K subs brother! So good to see!🏆🎉

[@never-stock-rc2968]

Imagine if that boat came with twins!!! I'd buy it for sure!!! Twin 8s!!

[@IRONCLADRC]

Omg that would be insanity

[@79ltd]

I installed the RCBB tabs on my 42 and got 73 with the tabs. I mounted them a bit above the sponson with a very slight angle down. I relocated to a different place on the lake due to the BIOTCH swearing at me the first time I ran the boat. It's not sheltered much and I'm fighting wind, ski boats and fishermen due to the season. This fall when things cool down I'll be better able to put down some good runs. I have only rescued the boat once since putting the tabs on. Still fast but way more planted. Love them.

[@IRONCLADRC]

Getting the blackjack ready she should be ready soon

[@911dott]

Great video!!! Tabs work very well.....

[@youtube.really.stole.my.handle]

Definitely agree with this man, RC BOAT BITZ does a absolute great job with all of their products and customer service!

[@IRONCLADRC]

Thanks for watching brother

[@RCplamodel]

That's a great boat ride!~~~ What a great boat! I really like RC boats, too!~~😀👍💪

[@norcalrc]

Looks like the 42 was enjoying the trim tabs.

[@IRONCLADRC]

Yea she's not landing on the hill as often with the tabs. No more battle scares

[@Dokroc78]

I know you don't want to like them trim tabs B, but man what a difference!

[@levihogge9144]

I ran my bj 42 for the first time yesterday on 8s only change I did was angle of prop and the boat performed nicely the video will be posted on my channel soon

[@IRONCLADRC]

Good vid

[@Rubio-of-6]

What run time are you getting with this boat

[@simonjandrell5897]

such a nice bit of Kit

[@SteveLane61]

Nice run Big B. Cats don't have trim tabs? As the good Dr Jet suggested in a recent video... just because everyone does the same thing, don't mean there's not another way! You've just demonstrated that 'out of the box' thinking can get great results 👍 Thanks for sharing buddy.

[@stevejackson3564]

Looks good. Set that boat up to turn at full speed for a 70 foot wide turn. Don't back out, if you can do that then it will be awesome

[@raydash2898]

So do the small set screws hold the tabs position without moving? They are a very nice design but the set screws worry me. Also is there any place to find them in the US?

[@IRONCLADRC]

Yes they work perfect. Horizon hobby sells replacement trimtabs

[@petergoodwin2465]

This was great to see, wife has a black jack 42 I'll be doing this to. Bought a self righting pursuit with the integrated drive. Has a 3674 and 180 amp seaking but no trim tabs, skips and bounces all over the place. I'm about to put trim tabs on it today from rc boat blitz. We have the normal pursuit and that boat is perfect. Thanks for showing us this .

[@IRONCLADRC]

Amazing how much of a difference the trim tabs made. Night and day

[@willon1206]

I just put a 150a raider esc in my black jack along with a 2000kv 6 pole dynamite and damn that esc is massive

[@IRONCLADRC]

Blackjack 24? Lol. That's crazy but freaking awsome good luck with the maiden.

We're did u place the trim tabs?

[@xillianto]

have you tried out expo instead of turning down the steering ? makes a better turning curve, specially if you got abit large rudder and so on.

[@IRONCLADRC]

Not on this boat but I will now thanks.

[@CARMELOGUARRASI]

Awesome boat

[@frederickgrassie3383]

How do you estimate the degree of angle on the trim tabs, just by eye or by measuring

[@IRONCLADRC]

Basically eye it with a ruler or straight edge on the bottom.

[@jaycevessier7554]

What size is the ul19 prop?

[@IRONCLADRC]

1.7p ' 1.6 dia

[@DJ_SHANNIMAL]

Hey man nice boat. So nice my friend and I just ordered. We both have the zee 9000 for our xmaxx already. Using these batteries with the extra weight might be good enough without the trim tabs? Also I saw you trying different props below. What have you found to be the best? I want to order that as well. Thank you.

[@IRONCLADRC]

The stock ul-19 prop is a good upgrade prop. Also oxidean Marine 5016 (3blade) power prop is a good upgrade prop. Yes 9000 zees should be perfect

[@insanesurfer23]

Do the trim tabs alone stop it from flipping? My stock one flipped so hard it split the hull!

[@IRONCLADRC]

Yes sir it definitely helps

[@paintendaveextremecollisio8057]

Nice man👍

[@35BMuu]

How are you liking them? I ordered the RCBB tabs before ever running my Blackjack 42 but since I am running the Zeee 9000mah 4s I haven’t had any issues with blow overs or flipping and I have been trying to flip it.

[@IRONCLADRC]

Love them brother.

[@35BMuu]

@@IRONCLADRC Thanks for the reply. You have the best informative videos on the Blackjack 42!! Thanks for posting them!

[@marxboatworx]

Great to see the BJ42 running again! As you say just depends what you want to do. Yes, takes the unpredictability out of the equation. Was more thinking for speed runs, so would love to see what you can pull out it. Just need a good long body of water now. Any luck with getting permission on the new spot you found?

[@IRONCLADRC]

The trim tabs work amazing thanks again. I asked the owner of the big pond I use to do my speed runs in if I could run my boats there i even offered him payment monthly, he stocks the pond with fish and didn't want ANY boats on the water. Grrrr. He owns the only 3 Large pond/lakes near me, so I have to run the big boats in the river, the river gets rough with any wind. I will try a legit speed run this week Weather permitting

[@marxboatworx]

Oh well, once you become a big time You-tuber, you’ll be able to build your own big dedicated RC pond!!! Are there any spare spots in your area? Maybe lobby the Jacksonville City Council, to see if they would build one?!? (Without Turtles and Ducks!!)🤣🤣

[@PigglyWigglyDeluxe]

Also, what do you mean “blueprinting”?

[@IRONCLADRC]

Blueprinted the Sponson ride surface I filled any imperfections/dips sanded high spots down flat FLAT to improve performance and handling

[@jaycevessier7554]

Hey big B!! What’s the biggest prop you’ve thrown at this boat? I’m up to a 1917 and it acts like it wants more. The faster it goes the smoother it’s tunning

[@IRONCLADRC]

Pranther 260. 60mm prop not good for top end but dang if it was fast out the hole.

[@jaycevessier7554]

@@IRONCLADRC haha holy shit that’s a biggin!

[@IRONCLADRC]

Yea I was looking at the 1817 for the 42 but didn't get it because I was afraid it would be to much. Lol. Good to know that 1917 was on point. Did you GPS the speed?

[@jaycevessier7554]

@@IRONCLADRC yes me and my neighbor gps out 42’s, with 1917 they both run 69 mph. And just to let you know, I just tried a 44 mm 3 blade 1.4 pitch, and it’s the best prop I’ve ran yet. 64 mph and literally glued to water.

[@jaycevessier7554]

@@IRONCLADRC I’m going to order that 3 blade and a 47mm 3 blade cause the temps were motor 101* and esc 120* and that’s in 74* water

[@PigglyWigglyDeluxe]

Have you ever rolled off plane with this boat? I never drive my Veles anymore because the damn thing rolls over nearly every time I turn

[@IRONCLADRC]

No this boat holds down in a turn. Lower the CG and it will turn better

[@Dokroc78]

My Veles rolls in the turns also. I think it's due to the squared off sponsons on the tranom. Proboat claims it was designed for SAW runs not cornering. I've found that's its better to stay on the throttle in the turns, if you back off as you start a turn it will flip. Also a higher torque servo is a must on this model. Hope this helps.

[@wheeliegriff777]

that's gotta be one of the best RTR catamaran boats!!

[@FLSharkdiver]

Thanks for the review .. I bought some trim tabs for my blackJack but i ENDED up taking them off but now that Boat Bitz makes some really nice ones i THINK i am going to give it another shot with a on my BJ42.
