Those pulsejets are insane. I've seen a few up in the air up north wher I lived up until the last few weeks. One guy I had to stop and make enquiries with - his jet was almost 3m long and the exhaust from his custom-built pipe fit my fist half. The intake was bigger still than 'wrapping' my fingers in a circle... Needed some sort of launch platform - lost me from that point to be honest. I thought 60mm EDF F-15E's were incredible haha!
Back on topic though...
Unfortunately, given the advice that has been coming from all angles, it really looks like I will be sacrificing the full scale of what I want people to SEE for something that I can AFFORD.
The hull initially was going to be a little shy of £100 - painted, primed, laser cut and glued together. All my own work of course.
So let's say £100 for the completed hull.
£200 for the new electronics
£100 for the upgraded batteries for when I eventually feel brave enough to risk the power (bear in mind it's only 2mm ply!!)
Plus roughly another £80 - £100 in bits'n'pieces.
Add on top of that, the 3D-Printed MiniCat that I'm just waiting on new nozzles for...
Will update after the weekend, as I'm about to call it a day - ice cold beer in the fridge and Breaking Bad for me. Tomorrow I start cutting. Will update later in the day.
Enjoy your weekend gents,
Dean

Haverlock,
I thought the BEC's require their BEC individually? There will be two, and they'll both have a motor?

After much deliberation, boat is coming own from 72" to 60" because of an exponential electronics' cost difference to overcome the drag.
Specs thus far are:
Twin 4084 1050Kv Turnigy motors:

Haverlock,
Thanks for such an in-depth post. Much appreciated - worry not about negativity; as you say - realism is the way forward and with the grief the wife is giving out, this MUST succeed lol!!
I've decided I am going to stick with the decision to bring the size down from 72" to 60" because I would like a decent cruising speed.
With the boat being the size it is, there's plenty of room. On which note, it's a V-Hull, scaled back to 60 inches, blueprint attached.
I've been advised that a suitable prop pair would be X465 Octura. They're huge!! Very excited to get this thing onto some water!!

I can bring the boat down to 60 inches. This relatively solves my speed issues, especially with the dual motor setup.
However.. Application of power is where I'm a little lost.
Prop suggestions anyone?
I'm thinking of starting off with a mid range 38mm.
---
Here's where I'm at so far with the heart of this boat:
- Twin watercooled 4048 1050Kv motors
- 4S 25C 14.8v 5200 Battery to start off with: 6S if that all stays happy
- Twin watercooled 200A ESC
- 38mm Prop (like in the HK Osprey 1057mm)
Whilst this is on the shelf pending prop advice, I shall go see the fireworks!
Happy Guy Fawk's everyone 😊

Have had a look at powerplant options.
Turnigy AquaStar T20 3T 730KV/1280KV Water Cooled Brushless Motor
SKYRC Proteus Water Cooled X520 730KV 1280KV Brushless Motor for Marine IM680
I like these as they can switch output power. Shame I'd have to bring the boat size down considerably to afford TWO of these!
Still looking for a reasonably priced 150A ESC.

PS. On successful completion, blueprints may be made available in various sizes, complete with electronics suggestions from what knowledge I gain from this build.
I also have another project that I'm documenting quietly on the side, which I shall release THE MOMENT she is seaworthy and running about causing acts of terror upon other RC boat enthusiasts....
Keep an eye on these spaces!! 😁 😁 😁 😁 😁

Hello everyone!
So, I've been searching for a fun community to share this project with for some time now, and here at model-boats, I think I've found just the right crowd!
So, brown-nosing complete, let's begin.
Initially, my interest pique'd having watched the YouTube video "How to make a scale RC foam board boat" posted by user Matthew Autenrieb. We exchanged some emails, I got hold of the plans, and began drawing up this thing in 3D.
That's when I caught the fever.

Derek,
Thanks for your reply mate. I like the sound of your boat - pic looks pretty cool! I'm assuming just a single drive yeah?
My boat will likely be getting very warm, as I'll be hammering it if I can... (Ducks are quick to respond to RC boats these days).
Do you know exactly what you're running just now, that I may use as a point of reference?
If possible, your data I'd love to crunch consists of;
- Water-ready weight
- Battery mAh?
- Shaft/prop material? (Balanced?)
Cheers!

HI all,
First post! Let's make it worth the community's while? 😉
I am wanting to create a 6S capable setup for my 72" RC Deep-V. I will likely run a twin 6S setup, pending costs, as a single engine setup simply isn't going to move this boat at a head-turning, lake-screaming rate of duck murder. 😁
Any advice would be greatly welcomed. Max budget for ESC/Motor/Battery is £140
Battery is not really too much of a concern in this budget (just want to know if it is doable) because I have several batteries I can series into 6S without trouble.
Regards,
Dean
PS. Have found a nice ESC:
125A Brushless Water Cooling Electric Speed Controller ESC 5V/5A SBEC
This comes in at £41 the pair including postage.
£100 left in the budget folks!!!
