I love your tenacity big B, you could make a bath tub fly!
That’s very satisfying to crack a problem like you’ve just done it shows you’re experienced in the hobby and we just love learning from you!
Happy dad day!!!
You have a small narrow boat with a very high center of gravity. With the torque of the motor and speed you are trying to get that heavy motor up in the air is a killer for handling. Not a whole lot you can do with what you have to make it great, just keep on playing to find a crutch to make it acceptable.
Try reducing your travel adjust on the turns if your radio can do that.
GReat VIdeos B! Lookin to purchase a NEw Mono Hull i take it out here on the lakes and wanna build up the Esc and motors, thinking Sonic wake, or impulse?
I've raced tunnels for over 30 years. I hold multiple current world records, and have won at the national and world level. Tunnels are kind of my thing. The roll over in the turn is mainly from the prop paddling accross the water. I've never been one to worry much about "CG". Moving weight is generraly the last thing in the fine tune of setup. My guess is the motor is too high. The best way to know is to use a slotted board at the back. What your looking for is the center of the prop shaft in relation to the rear sponsons of the boat. Also the depth of the sponsons plays a role. tunnels wiht real shallow sponsons can't run the motor very high. Regardless I would lower the motor about an 1/8 inch, until your rollover issue goes away. The other thing is to stay on power as much as you can. power holds the back end in turns. if your on throttle and the boat is spinning out its 100% motor height as the main issue.
Great video luv the anger grunts lol happy fathers day Big B 👍
That's what I though, boat not heavy enough to keep the fin on the lower unit in the water. I don't have this problem with my tuned Wave Master as it have 2600 grams with oldschool brushed setup. Also when you lowering the engine at the end, the sound is exactly the same as on mine.....it's like "leaking soda stream machine". It's bubbling a litlle bit👍Wave Master have almost the same flex in the hull as yours, it's also ABS boat. But as I moddified battery box (cut out the old one), during the proces I put foam inside complete hull. It's adding floatation and reinforcing the plastic a litlle bit as well.
I totally feel the "frustration" trying and trying (like my twin) but you got some base setup from were you can work on or go back to. I love that thing because off the looks. Wouldn't buy it because its not there to buy, or stong enough to do the things we normally do with our boats, but you almost have to like that little boat...
Going for some testing again, its beautiful weather last days so trying to get lot of time on the water trying to adjust my damn boat to handle normally.
Happy fathers day...
i couldnt help but notice these style hulls turn left better for me than right or clockwise with riggers...
thats a bad ass boat big b.HAPPY FATHERS DAY brother
yeahh nice tinkering & tune BigB Happy father's day!
Happy Father's Day ! You have her running good my friend. Did I hear you right ? You're pulling molds from hulls now ? I'm interested !!!!
Thanks, unfortunately no I'm not, I was saying I didn't have the time to pull a mold
Nice one big B, i call that real progress, Its made me look at building one from scratch and the outboard in carbonfibre,That way i can get a lower CG and stiffer hull.
I've been considering building a lower unit myself, u think it would be a cool project for sure.
I think you have it running great for what it is and considering how old it is Big B. Hope you have a great Father's day! 👍🤙💯
Thanks, you too!
Your doing great get it dialed but can you just go wider on your turn this would never be this tight in any race course
Roger that
Love your channel, your killing it. I’m seeing boats going about 110mph on TH-cam, the Zonda.There about a year old, it’s a big boat. It’s moving out
12s

Happy pappy day to you as well,. Didnt make it out yesterday so I'm gonna get out today kick back on the hill and throw some rooster tails at olander pl. Sylvania ohio if anyone in the area I'll be there about noonish, peace and love to all the worlds greatest Dads .
I'll be running 3 boats harbour tug bj24 and swv2 aka booty 1
Wish I could join you, 😪 have fun
Happy Father's Day!
Happy Day of the Dads!
Hey big B the newer tunnel.hull have stumble blocks in the tunnel towards the bow I just learned that they are there to help with the turning. Also learned about the old K&b auto trim . It would induce positive angle in a turn to keep the boat from diving in the turns.
Happy Pappy Day
Enjoy your Blessed Day with the family
That boat is a challenging little bugger for certain! Been closely following along with all of the suggestions and comments. I've been considering the weight of the motor in those turns being the main culprit for flipping it, but I'm a noob to RC boating and would not try to suggest that I know anything. You are an excellent craftsman and have done great work on setting up that outboard in my opinion.
On another matter, what servo would you recommend as an upgrade for the sonic wake v2?
I was running a cheap 20kg ds servo in mine worked just fine if 20kg isn't enough for your taste they offer a 35kg option
@@IRONCLADRC Thank you Big B! Preciate cha Brother!
Like I said in a previous video, the mrp miss budweiser actually had a turn fin on the sponson so I think that’s the ticket
I'm sure you know by now, but that model came with a turn fin mounted inside the left sponson and they were made to turn left mostly. This was hobby grade back in the late 80's, glass boats were super heavy back then and not electric! You have this running faster than we ever went back in the day, so nice job. another thing I wonder about it the height of the Kyo outboard. it is larger and heavier than the MRP outboard. I'd love to see a hyperdrive or whatever the modern electric K&B drives are that are made of plastic. I still have my Bud Light Tunnel, autographed by "the" Man himself Bill Seebold #7. Mike is his son and he raced #11.
You've come a long way. RC F1 tunnel hulls are converted to inboard & fake cowls.
1 to 1 f1's can pull a 6G strain, due to (quite) different sponson layout ?
And they turn left.........
Happy Father's Day. You need the K&B 3.5 outboard trim v block that's adjustable. Search K&B TRIM V BLOCK
I'll check it out thanks
@@IRONCLADRC you could make one. 😊
K&B OUTBOARD 3.5 VINTAGE AUTO TRIM NITRO
I had one of those in the 90s basically a toy, maybe hobby grade?, although Kyosho do a nice model and in standard trim out the box, mine was wonderful to drive, seem like you have a lot of power for her that she not designed for , still... good fun , best tunnel hull boat I had was an old wooden Dumas kit with a 10cc nitro in her... wow rocket sled!
Happy fathers day did some testing on the recoil 2 today myself sonic wake rudder ran separate cooling on the esc and motor ran on 5s cheaper ebay esc this things nasty stock motors staying cool but for how long with the sonic wake prop
You need a skeg on the inner surface of the right sponson relative to the cg,,,,
Thrust angle of the prop along with cg can do a lot when tuning. A turning fin is going to change everything as well. Nice R&D session!
How's the IRONCLAD perch going?
What do think would happen if you put the fins on this boat?
I bet it won’t spin out anymore
We're about to find out mid week this week😊
Your trying to turn it to tight. I have never seen a track with that tight of turns
Happy Fathers day everyone , great job Big B!!!!!
Tryva octura x437/3. I ran those in the APBA regionals for years (till they got bought out by NAMBA). Someone else says you're getting prop walk, you need a three blade with tunnels W/lift. Ran them on HOTSHOTs and Prather hulls with many ribbons behind my career.
Roger that, thanks for the information, I'll definitely look into picking up a 437/3. That prop would work well on a few of my boats. BG4L
Nothing will turn in the water going that slow - all you need is speed!
Maybe trim the drive down just a smidgen too 🤷
can it be the rotasjon torq of the motor that influense the left turn?
This boat was not built or meant for modern brushless power. It is what it is man, a 30mph runner. Love it for what she is B.
Oh, trust me, I do, I know what it is. Alot of guys were expecting a race performing boat.... this is one of my favorite boats at the moment, the challenge alone makes me like it even more.
From one proud daddy to another , I wish you a wonderful Father’s Day bro
I appreciate it, right back at ya
Love the design of this boat. Pretty cool
It's getting better for sure! A turn fin is an easy fix, if you can reinforce the fin mounting from inside the hull. I really love the old school looks of this one. Looking forward to see what you will do to it next 😎
Working on the turn fin right now, straight fin correct, it doesn't need and angle on it right?
@@IRONCLADRC Yes, I would start with a straight fin. If it still flips sideways, you could try a straight fin under an angle, or a bent fin. It's a tinker and tune process I guess. You master that part 😎✌
Roger that thanks.
Happy fathers day boatgang 👊
Cool boat i got alot of old school rc's and i got one of these too.. i totally get why u call it a toy grade lol yours in much better then my stock setup lol
Thanks, yea she's slightly modified lol
This video reminds me of me!!
I think the outboard is too high,but i dont know anything about this type of boat
That makes two of us. Lol
Definitely a big improvement! Can’t wait to see it with a turn fin!
Fingers crossed! It's an improvement
👍
Right on! Good work Big B! Can’t wait to see the custom turn fin & mount you come up with!
I want to know the size of the flaxible shaft??
I think im running an upgraded. 150 cable with 3/16 stub shaft. ( either .130 or .150) Check the playlist I have a full length kyosho dolphin 2 outboard motor driveline upgraded
@@IRONCLADRC
i have one..what is the best kv motor for me to keep in there???
Big b I need help with a few boats get with me brother
What's up
@@IRONCLADRC bj 42 and 29 props esc all that they flip over every time
Trim tabs help the bj42 with a 5016 3 blade from ose or Oxidean Marine
Upgrade the veles 29 rudder to the dual pickup ul19 rudder from ose that helps the low speed flip also I lowered the battery tray in my veles for a lower cg.
@@IRONCLADRC any other mods I can do for heat
Bro, Try turning left .
It turns great left, but I'm use to right turns. Left turn to me feels uncomfortable natural
@@IRONCLADRC th-cam.com/video/QzqXuGfnyKQ/w-d-xo.html That's funny, I raced closed course for 10 years and we only turn left.
1to1 boats have a clockwise rotating propeller, rc boat propeller rotation is counter clockwise 1to1 race in a right circuit, 99% of rc boats race in a left circuit
@@IRONCLADRC Counter clockwise, yep, that'll do it. Didn't know but that enplanes everything.
F***ing son of a.... we all have those days!
