Well, the first kits arrived today for the ML Boatworks Sport 20L 33.5" full P sport hydroplane. I quickly framed one up as I just had to see how it looked compared to the Sport 20 31" version for P-limited applications. This thing is going to be awesome! As you can see, it has a wider stance, its longer, and it engulfs the Neu 1512 motor I layed in it. As you can see, (2) Hyperion, 4s, 35c, 5000mah packs sit easily inside. It has a 5" engine well, with plenty of space under each side deck. Uses the same cowling as the sport 20. It also has the built in Steering Servo Frame so no extra servo bracket is needed. Should be awesome out on the water! I will be quickly getting this one ready for its first run! Enjoy the pics. I did side by side comparisons, 20L vs. 20 in the pics. Enjoy, Mike www.ml-boatworks.com (http://www.ml-boatworks.com)

And as you can see, both hulls use the same cowling. The soon to be ready Sport 40 also uses the same cowling!

[Darin Jordan]

Mike, what are you using to glue these together at the frame joints?? Is it CA??

Just wondering how you are able to get them together so quickly and so nicely, because, well... I want to be able to do that too!

Look GREAT!

[cybercrxt]

Hey Darin, its CA. I put just enough to hold the framework, then I thin out west systems epoxy enough that it will flow up underneath the joining frames. That is what creates the permanent bond. Im not sure what else could be used to hold things fast do you? Mike

[cybercrxt]

More progress today on all the hulls, and did some initial fitting on my Sport 40, 6s1p either 45c 5000mah or 35c 6500mah setup, Neu 1521...Gonna be TONS of room in this thing! Mike

More done, and as you can see the first 20L and 40 hulls are rolling off the assembly line. I hope to have them both in the water in the next couple weeks! Enjoy, Mike

Got the Sport 20L and 40 both built and painted, 20L is rigged, and I am heading to the pond in just a few minutes to see how it does. I think its gonna be good! Feedback soon! Mike

[cybercrxt]

OK, Just got back after running two heats with the 20L. Wind was 5-10mph, wave action was 2-3"....Quite simple, its faster than I expected, turns amazing at full throttle, and the initial runs were so impressive, I am considering taking the 20L and the 40 Q hulls to the SAW races in two weeks. The 20L, with zero tuning is already in the 65mph range, NO lead up front (had 3 ounces up front, and removed it as it just was not needed), and had 1-2 degrees positive in the strut. The center of gravity was about 2" behind the sponson heal, and the boat never once tried to blow off into the wind, or get that loose for that matter, and the setup I have right now should cause it to get very loose, but the hull just doesn't. It wants to go faster, and it seems the faster it goes, the more locked on it becomes. With some more tuning, cutting down the rudder about 1/2", I expect to have this boat in heat trim doing around 70mph. Not sure the Castle 1415 2400kv can take it tho, more testing will tell. Right now, all I can say is I cannot wait to get the sport 40 hull rigged, but I have got to get some of the backlog of sport hulls finished up this week if possible. Below are some pics of the 20L and 40 in their new paint schemes. The 20L uses the castle 1415 2400kv motor with 5mm motor shaft upgrade, hydra 240lv, cap bank, (2) 3300mah Hyperion 45c 4s packs (4s2p), speedmaster standard flat bottom hydro 3/16" strut, mini speedmaster rudder, and Virginia Craftsman sport 20 turn fin. BTW, as you see in the pics, I am now calling my sport hydroplane line the GP series. The sport 20 is the GP310, the sport 20L is the GP335, and the sport 40 is the GP400. I knew I would figure out a name sooner or later! As soon as some videos are able to be made, they will be. Hang tight! Mike

Fantastic Mike brilliant work.

[cybercrxt]

As some of you may your may not know, I was offered my old job back last week, and decided to take the job. It is forcing me to restructure the builds I have on the list. Some that are not prepaids are dropping off, espcially if I have not had contact with that person in a while. Once I get that backlog caught up, I will then be more open to adding any additional builds to the list. If you do not see your name on the build list, please PM me about it, and I will offer you a kit to build. I just have to get some of the hulls that had deposits on them done, and done soon. Its put a lot of pressure on me, and its time to get those settled up. Here is the current build, and kit list for all the sport hydros. If you ordered a tunnel, or scale build, you will not see your name on this list anyways as its only for the sport hydro crowd. Thanks, Mike

While I have been back at my full time job for about 2 weeks now, I have been finding time every night to get something done to the sport hydro build list. I am very close to having all of the hull actually in one piece, and depending on what happens from there, some will be ready to ship this week!

I did make it out to the pond yesterday, a new pond that is full size where I can really stretch the hulls out...finally, after 4 years of running in a puddle! It has become very obvious that all of these hulls REALLY like an X series 2 blade prop. The sport 40, with a 1521 1Y 1577kv on 6s power, ran a stock, cleaned up x455 yesterday, and it ran so clean. I had been running an ABC H7, but wanted to see what the X series would do, and it just got the rear of the boat way up, and the hull stablized, and moved out. I have a 1527 1.5D 1500kv motor on the way right now for that hull, so I can push it even further.

The Sport 20L is fast right now. I would say its a touch faster than the sport 40, but that is only due to the TP Power 4082, 2200kv motor is a great choice for this boat. Its big enough to run cool, but not so big that I had to rearrange anything to get it to fit after pulling out the 1415 castle. (The 1521 1Y in the sport 40, to me, might be a little on the small side for a hull that size. It comes back cool, but the x455 started warming it up some) The more I run the sport 20L, the more impressed I am with the 82 series TP power. It comes back very cool. Right now, the hull has a highly modified ABC H5, but the next time I run, I am going to put on an x445, then x447 and see how it does. Being so pleased with the X series on the Sport 40, I have to get one of the 20L as I think it will let the hull run flatter.

Now that I have a good pond to run in, I hope to get some good videos if I can get my co pilot to stay in town for a weekend. No matter, I am accumulating setup data every time I run the boats, so if anyone has any questions, I can definately guide you in the right direction. Well, its time to get in the garage. I have a lot of time today to work on the builds! Mike

[Jesse J]

Hey mike,
I am way behind with my build, but am super psyched to see her go.
What was your water like? And your running weight? CG 2" behind sponson heal-do you expect that to change with weight and/or power options?

We generally have pretty rough water so I am going a little heavier and lower kv motor (1521 1.5d) - even though you have different recommendations.

[cybercrxt]

Jesse, I think a 1521 will work great in the GP335 (new name for 20L)

Well, I got to the new pond today, unfortunately a car show was going on, and the car show bunnies would not let me park in my normal spot which allows for normal oval running, so I had to run like you see in the videos of the GP335 and GP400. The water was abnormally calm today. Usually its been really rough, and this lineup of hulls REALLY likes the rough stuff. I will make more videos when the water is worse with some wind to show you they perform even better under pressure! Right now, I am going to say the GP335 is faster than the GP400. I am really thinking about making a 36" GP360 for 6s power as I think the GP400 could be a really great 8s hull. The GP335 is running a TP power 4082 2200kv motor and fightercat 2-8s 240a esc. They are coming back cool, along with the 6600mah 4s 45c hyperion setup. The GP400 is running a 1527 1.5d 1500kv motor and Castle hydra ice 240a lv esc. The temps on them are fine, but I found out today that the 6500mah 6s1p 35c hyperions I am running need to have the ground wire shortened inside the battery shrink. I did not realize the ground wire ran the length of the pack, and it gets hot. The cells were fine, but the wire is stressed from that added length. None the less, both hulls ran really nice today. I am learning that x4 series octura 2 blade props are the way to go on these hulls. The GP335 was running a cut down to 45mm x450, and the GP400 is running an x455. Enjoy, Mike

The boat looks great Mike.

I am heading out today to run the 370 again to keep dialing her in. We are getting about 63-64mph in oval trim which is pretty competetive here round the bouys.

The next step will be a CC1518 and 6s for some straight line fun.

[Jesse J]

So she is almost done...:cool2: still bare from the painting process and lacking a windshield. anybody see the ears on that dog in the second pic???
This baby's the rebirth of my first Oberto (my avatar). :bounce:

her first race is next weekend...
she is PSYCHED to get out there and show em who rule!:banana::banana:

Hey Mike if you have any graphics with your GP335 or anything else to show you designed it, I would be glad to incorporate them in my scheme!!

[cybercrxt]

Jesse, That looks great! Really nice work on the build, and looks like the paintwork is gonna be nice! I do not really have any decals off hand. You should put the oberto stuff on there!

Here is the updated list. As you can see, things are getting finished up with the sport hydro list!


Sport 20
1) MarylandFE- Built, finalizing
3) Mike Buck- Built, finalizing

[Jesse J]

So I got her done... She is 9.4lbs, 4S2P 10,000 mah. As she sits, cog is almost 2" behind sponson transom and starting with an x450.
I posted some interior pics next and some vid in the video section

[cybercrxt]

Jesse, please send me a pic of your battery placement and motor placement. I am going to switch to a 1512 1.5D myself I think and would like to see how you are shoving so much battery in there!!!! Talk soon, Mike

Oh, I have a vector file of the ML Boatworks logo. Feel free to email me at madaccord@hotmail.com, and I will send you an eps file tonight. Mike

[thercman]

I am in the market for a boat and love the idea of building a kit. They have been hard to find now with all the RTR's out there. Anyway, I am looking forward to ordering a Sport 20l kit as soon as you have them listed on your sight. Cheer, Greg

[hazegry]

just pm mike I am sure he can get one out to you

[cybercrxt]

Greg, the 20L and 40 are available now, i just have not added them to the online store. I have an extra 20L kit coming to me right now from my laser guy. If you want to call dibs then its yours! Pm me for details. MikeOn a side note, the sport 20L is now running 62mph on 4s power in heat trim, and i have the sport 40 running 67mph in heat trim on 6s power. Both hulls will be faster soon as i am not stressing the setups or hull yet.

[cybercrxt]

Anyone finished their builds yet??

[KartRacer]

I am also in the market for a 400, can you provide pricing on a build of ARR?
