Great build. My 2 cent, programme the esc with 100% endpoint. Then dial it back to 50% or less to get a baseline to plane off. Then increase as needed, it will double your run time

It's a beautiful creature. I think that this catamaran need of 12s and will be simply perfect. Stay fast. Sebastiano from Italy

I built that same boat with that pdf file out of all wood. I got it to 72mph then I hit a stick that I didn't see and that was it. I got all electronics back and were still good.not so much for the wooden hull. Nice build. Try 2 blade props for higher end speed. 3 blades are for acceleration not for all out speed.

Sweet boat!!! You could heat sink the ESCs to the hull and I bet they would stay super cool!

Absolutely killer boat it's unreal haha hopefully it gets sorted as it has so much potential i haven't really seen anything like it in the hobby nice job, does run better on 8s but super wet as in the bow digs into the water all i can suggest as it's a aluminium hull and i am only used to fibreglass but it should make a difference is to raise the drives more and increase the rudder angle back if you can and move what you can closer to the stern and higher lift props, can't wait too see the boat come along but considering it's the first i can't believe how well it went

Amazing build I I probably go higher than 8s beautiful boat good luck.

Awesome build congrats looks great , boats running a bit wet but that's just a strut adjustment as I'm sure you know...

I commend you for your wonderful idea and craftsmanship.I also want to make it with aluminum.😄

G'day mate wow what a beautiful boat It will be awesome when you get it sorted 👍👍

Wonderful build and workmanship. I think the teflon issue was due to a vibration. You can hear it vibrating badly wheb you went to the higher voltage.

I used the exact plans to build my boat!

Dude! That's badass! Any new content on this boat?

Honestly 4 4s packs in parallel isn’t very high for a boat this large. I would like to think you could run 10s to 12s on each side. I would try running two 6s 6000 with a high C rating in Series on EACH side and try raising the strut acouple MM and I bet you will be in the 100mph club! But that’s just a suggestion, you welds are looking very nice, it’s not as easy as everyone thinks to get a nice water proof tig weld after grinding them smooth!

Get 200 amp esc for each motor and 2 4s in series

Awesome work. Looking forward to the new batteries. How fast do you think currently?

very nice work, can we know the weight of the beast and then its size pls

Only wondering...why make this? There are Mystic cat's available from a few manufacturers (Radtek, MHZ, Central RC), in fiberglass, carbon fiber, and carbon-Kevlar, between 40 and 96 inches in length, that will hit well over 100mph with the proper electronics (Scorpion, Lehner, Castle, NEU, Flier, Swordfish, MGM, Schulze). Why did you power a hull this size with Leopard and Turnigy electronics? What were the ESC and motor temp's after your test runs? Are those 0.187 flex shafts? Was this simply a proof of concept for some future project you have in mind, or were you able to build this boat for under $2,000 USD? Typically a build like this would be closer to $4,000-$5,000, on a budget, and the speeds you should expect would be no less than 80mph with a quality hull like HPR/MHZ/Radtek (CRC Mystic runs pretty wet, so not as fast as the others).

Two new videos out now

Thanks for showing how to build this hull. How thick is the aluminium?

How much does it weigh?? My first offshore cat was an Aeromarine 42(I thought) with 2 CMB.90 engines. Problem was, it was a poorly done copy of an Aeromarine Laminates hull layed-up 3 to 4 times too thick. Weighed about 25lbs and was a slug even with over 10 hp of power. I got my tail kicked by boats with a single smaller engine. Weight is everything in modeling. That would make a great model to make a mold with and lay it up light.

where did you find blue print for stringers and ribs to design hull?

Wonderful engineering, but for the rest, the electronic parts & components.... Uuuu🤔hhhhmmmmmmmmm.... 🤔 🤔 🤔 🤔 Condivido, nei fatti, appieno con il commento del mio connazionale. Ed anche di altri esperti del settore. (presenti qui fra i commenti....) 😌 😌 😌 😌 😇😉😉

What an obnoxious bit of noise pollution to ruin the tranquility of whomever lives in that (formerly) pastoral setting.
