    I thought you might be inspired by that. Your dear wife might like those pics too, if she loves that boat so much.
    Yes. It is an ML Boatworks kit.
    Unfortunately he didn't do a build thread on it. Sorry.

    Mike.
    Here's a bit more inspiration for you.
    We had another round of 1/8 scale racing on the weekend & here's Johns' Bud in its first race. The other boats have had a year of racing & tuning behind them already, so for the first race it showed that it is a good boat to drive. And I think he was being a bit conservative with it too. It only had a single test session, 2 weeks ago, before this race

    That was one of my kits? I would guess the 108 kit maybe? Looks like a lot of fun!

    You are spot on there Mike. It's the 108. If you go back to post #59 you will see some nice photos of it.
    And yes it is a lot of fun. I managed to take top honours for the day with your Lauterbach kit of the Miss America IV U-36.

    Paul....
    That is really impressive....and that boat looks great on the water. I think those 1/8 scales in the video have got a bit more speed than my Miss Elam that's for sure. At least it looks like it. Didn't really have the opportunity to be around the guys at the club much for testing and tuning. Hoping I get the chance this summer and see if I can get some good speed and performance out of her. It needs something, otherwise those other 1/8 scales are going to blow me out of the water. But maybe with a 20lb boat I can't expect much more...idk.

    Be really interesting to get some specifics on John's setup.....motor, ESC, batteries, prop info, approx. weight. Also info on the canopy parts, mock motor etc. Did John do all the main art work via painting or are those graphic inlays...like the gold etc. If they were all painted that is amazing work....This painting thing is an art that's for sure. But I'm learning...LOL Will have to do some major inquisitions on how he did that work.

    Mike...How is that 108 kit to build? We talking about Jigs etc. in order to build a nice straight boat? Dang...Looks like I'll have the 108 and the 310 to plan on this fall....LOL The 380 is still in prime only....still waiting on Jeff to send out the 380 graphics. If he doesn't send them out by today for the weekend I'll be looking for something else real quick this week so I can get this project done this weekend for the race coming up on the 24th of this month.

    You guys take care....and talk soon.

    Mike

    Mike, its a strong kit, the 108 I mean.. and tons of room inside. I used it as a base for the Squire Shop I built...just extended the transom an 1 1/2" if I remember right. Here are some frame pics. I have different versions of this kit too..one is a version with quarter round at the front like my sport hydros and 3/32" ply. The one show below I think was the mild version. Mike

    Mike.
    I'll tell you what I remember about Johns' Budweiser.
    Motor is a TP Power 4060, 1030kv I think. Running on 8s1p spinning an X450 prop.
    ESC is a Swordfish 240A HV
    Both John & a friend of his painted the hull

    Graphics are from Thunderboat Graphics.
    http://www.thunderboatgraphics.com/

    Dummy engine from Classic Hydros.
    http://www.classichydros.com/#!/Hydr...=0&sort=normal

    But Hydroscale Creations also sell a resin engine kit.
    http://www.hydroscalecreations.com/M.../MiscItems.htm

    Cowling from R/C Boat Company.
    http://www.rcboatcompany.com/Cowlings.html
    But Mike at ML Boatworks also makes a variety of cowlings, so check with him too.

    Thanks for the congrats on the U-36. But the last race was handed to me when Darryl had trouble with the cowling & then flipped. But I'll take a win any way I can. The water was a bit choppy for a shovel running against a couple of pickles.

    Hey Paul....
    Your boat actually looked like it handled the rough water pretty well out there. A little bouncing around, but it stayed pretty stable. OF course like you said, sometimes you just take the win anyway you can...lol Happens with the real unlimited too!...lol

    Thank so much for all the information on the Miss Bud. I'm still scratching my head trying to figure out the paint sequence on the hull and how the curves where painted....LOL If you ever talk to John maybe he wouldn't mind divulging his technique....LOL

    Yeah. She's a good ol' boat. I ran a smaller prop for that last heat & it kept her a bit more settled than the previous two heats.
    I'll probably see John this weekend, I'll ask him to email me over a spiel on the painting process, & I'll send it over to you. John doesn't get on these forums much, apart from a bit of reading. He should though. He has a lot to offer. DO YOU HEAR ME JOHN!!!

    I've got to say, I'm loving the look of the 'Squire Shop' Mike. Mainly because of the motor being behind the driver. Might search for some other boats that used that hull & Motor configuration. A more obscure or less famous one.

    Cheers.
    Paul.

    Default Painting the 380 Today.....Not a good day!

    Well the painting did not go as planned today......

    Finally received my graphics yesterday, so started to prep for painting today. The primer was all sanded with 600 and wiped down with a tack cloth. Hung the parts in the booth so painting could begin today. Made sure my compressor was working properly and got out the bit bigger HVLP gun with a 1.4 type to spray the clear. The emerald green is HOK that I purchased in a spray can. The clear is a urethane HOK USC01 with a catalyst and slow reducer. Cut out all the graphics for the hull and canopy.

    So started with the green and everything turned out great...[spray can] Really love the color. Applied the graphics and all went well.

    Then prepared to shoot the clear after about 2 hours dry time. Mixed everything up and did a test shoot on test paper. Fan and product feed looked good so started to shoot the boat. Started getting splatters of clear so turned down the feed still to much....I almost had it down to about 2 turns out to get a nice mist. Then I notice all sorts of running starting and dripping......
    Well this clearing is all screwed up now. And to make things even worse the canopy parts that were setting on a box with a paper covering fell off the box and you guessed it....it had some clear over spray on it and picked up a bunch of crap off the floor in the booth.....UHG!!!!!

    So I guess I'll have to wait for the clear to dry 24 hours and go back and do a lot of sanding with 800 wet being carful not to go thur to the color, but to level everything out. Then re-shoot the clear again. The canopy might be a little tuffer. Was planning on lightly sanding those areas that got chipped up and then scuff the rest with a maroon pad. Then very carefully re-spray some green to cover those areas being careful to not over spray the graphics. Then shoot the clear.

    So have lots of work to do!! Appreciate anyone's experience and other ideas that I may look at doing to take care of this. Gun setup or my corrective actions to take care of the problem. Anything at all would be great....

    So included some pics just so you could see the color. really hard to see the runs and all from the pictures, but they are there.

    Thanks Guys!!

    Mike

    Default Painting complete

    With a lot of sanding and paint touchup on the edges finished with the last 2 coats of clear coat. Still not one of my best efforts due to a couple of bad planning moves on my part. Even after all the sanding still have some areas that did not finish the way I wanted. Everything went great through the paint work until I got to the clear coating process. On both my Pearl and the GSX380 I had problems.

    What did I learn....Really need to move slow on the final clear coat process. Thin/medium coats are best making sure the coats are being put on evenly with plenty of overlap. Double check your gun settings making sure the pattern is a nice even oval with a good mist of clear...no spitting and splattering....means the fluid flow is set to hi. The second try went much better and I'm still happy with the result even with my initial goof up.

    I love the emerald pearl green with the silver graphics....

    Not going to have ready for race day this weekend, but it doesn't t look like they are running that class anyway. Still have some electronics to complete and props to sharpen and balance.

    Beautiful boat to build....Cudo's to Mike on another great design...:)

    Speed810

    I just finished my GSX380 and put it in the water for the first time this past weekend. I am using the Leopard 5698 and an X457 prop. I attempted to use a Hobby Wing "SeaKing" 180 v3 Amp ESC just because I have a couple of them. Well the boat would only make about half a lap at speed before the ESC would shut down due to thermal overload. I am interested in how you made out with the Swordfish 240A ESC and how the wiring was done.

    Anyone with useful comments is welcome to chime in Thanks in advance for your advice.

    Hey Rat....I’ve been running the swordfish 240 HV for 3 years now in my Q boat. No problems at all. Matter fact they now have the new X series. Check them out.

    IMO...those SK 180’s will not do the job in a Q boat. Pulling way to many amps.
    I have an X200 amp in one of my P-sport boats and it works perfectly.

    So far the swordfish ESC’s have not let me down.

    Thanks for the quick reply. if it is not too much trouble could you post some pictures of the battery and ESC location.
    Also did the weight ready to run come out to be and where is the GC?

    Thanks

    Default Q esc

    Hey Rat... the layout for batteries and ESC Is similar to this picture. This was a new ML 380 that I built for a buddy. The only difference was that he is using the Mamba XL 220amp. ESC. The Swordfish 240 will be right up against the bulkhead except you’ll stand it up on edge instead of flat in the tub.
    Depending on where your motor is mounted this should give you plenty of room to move your 6S packs around for obtaining the correct CG.

    I have been finding that the ML boats like the CG right around 1 1/8” to 1 1/4” from the trailing edge of the sponson. Also note that the motor I’ve been using is the 5692.

    Hope this helps

    Speed810,

    A picture is worth a thousand words, this helps a ton. The motor size was a typo on my part I am also using the 5692 in the same location as your build. Thanks for the info.

    Have a great day

    Speed810,

    Did you experience any issues with getting the boat up on plain from a dead start. My boat tends to act more like submarine.

    Hey Rat.... Sorry its been so long on getting back to ya. Been a lot going on since the 1st part of Sept. with family stuff... Yes my 380 would act like a sub all the time.
    I set the CG back to around the 1.5' to 1.8' behind the sponson heel. Had to add weight to the transom. Did some more tweaking on the strut and raised it so it would kick the front up. This all seemed to help, but its still not as great as I was hoping for. It is blistering fast...but very unstable. I have had so many times when it will be running down the front or back stretch, full out, stable and then bang...out of no where it dives right down. Sometimes I won't see it again for 1 to 2 minutes when it finally comes back up. I have had the darn thing suck in the bottom mud for 5 minutes and then all of sudden...boink...it pops up.

    Let me know if you were able to owrk out any of your problems with it and we'll compare notes.

    Speed810,

    I got out this past Sunday with my GSX 380. Over the winter I moved the motor aft 1". I put an X452 prop on it which is a little small, and for the first time the boat from a dead start jumped up on plane and took off fine. I have no idea what kind of speed it was running but the boat finished two runs of 7 laps around our race course with no issues. Everything came back to shore cool but I suspect the water was chilly helping keep things cool. I need to check where the balance point is and I will get back to you. I hope 2020 is a better boating year than last year. I was thinking of changing my initials last year to DNF.

    Hey Rat....
    Sure be interesting to know where the new COG ends up. Can you give me a measurement from the back of the sponson bulkhead to the top edge of the motor? We'll see if we are close on yours and the second one I built.....LOL I know on last years 380 build for my buddy I ended up with the motor about an inch aft of where mine is. Figure I'll tear the motor out of mine and relocate the motor mount and stuffing box. Sure seemed to make a difference on my buddies boat.
