Cozy: my fast electrics

[Joern Markset]

You make a lot of very nice stuff, looks like you are very enthusiastic

 

[Dirk Jan Cozy]

Thanks Joern . I ldo ove building boats and running them. I hardly sell my boats, that's why it might seem I build a lot
For example, the Speedliner I built 10 years ago already.

Here's the newest boat of my fleet. It's a 32" Wild Thing with a 6S setup. It has a Rocket 4074 2000kV and a Flycolor 150A esc.

I've ran it 6 times so far and I'm still fine tuning it. It's already my fastest boat with 64mph on the third run.

Here's a running video of it, testing a few props:

You're going to need a bigger lake Dirk !!
That thing is flyin'!!

 

[Dirk Jan Cozy]

Thanks Wasted Wages It is fast for sure. I think with little more aggressive prop, it could reach 70mph with this setup. But finally, I like to set it up for heat racing / running laps.

Next up will be paint and finish. I will update in a few weeks!

Today I pushed the Hydromite and made a small video again:

If that was where I live in NJ and I was running there by those houses I would have the police swat fbi the national guard and the CIA there in5 minutes lol

 

[Dirk Jan Cozy]

Why would that be? Because it is in a residential area? This boat is kind of quiet still, but my Wild Thing mono is on the edge, noise wise

I ran my Wild Thing last Friday at a RC Powerboats meeting in the Netherlands.

No chance for real high speeds, but it is interesting to see how the boat handles choppy water:

Today I took the Hydromite mini hydro to the pond. I made a video of it. After 13 years it is still running nicely!

Hi fellow RC boaters. Last weekend I took my F1 Tunnels out. Here's a video of my DIY 23" Tunnel.
After 9 years it's still going strong ✌

 

[Dirk Jan Cozy]

Today I met one of my friends who built a Cozy F1 as well. We had a nice run together

 

[Dirk Jan Cozy]

This time I made a cost breakdown video of my 23" F1 Tunnel.
My friend made an inboard version, which I also cover.



If you like to get the plans, let me know

 

[Bret Muldner]

Nice looking Hydro and nice electric set up.

 

[ACTION JACKSON]

Enjoyed your video. I really like the idea of a inboard motor with a strut & rudder. I belive this should be allowed in impba & combined with the outboard tunnels.
Guess they might be afraid of advancement.

 

[Dirk Jan Cozy]

Hi guys, I made a video of my DIY collection of RC boats. I got too many projects, but I enjoy every second of them

Last weekend we had the Dutch RC Powerboat event. Gas, nitro, electric are all welcome.
Gas and electric have their own ponds next to eachother. It was a great day, just a bit too windy / choppy water.

Here's a compilation video of the event:

Here's a compilation video, where I cover almost all setups that I tried on the Wildthing. From speed running to oval setups.
It might be a good reference if you're running a 32" mono

 

[Dirk Jan Cozy]

I ran my 33" F1 T800 together with a mono boat. 2 different boats, with different power setups. But pretty well matched!

Arrow Shark mono:
Length 35"
6S 6200mAh
4074 2000kV
Flycolor 150A
43mm 1.6 prop
Weight ca 3500 gr.

Cozy F1 T800:
Length 33"
6S 5200mAh
3674 1650kV
Turnigy Marine 120A
43mm 1.6 prop
Weight ca 3100 gr.

The mono has more power, but the top speed yesterday was exactly the same: 54mph.

 

[Dirk Jan Cozy]

My latest project is a Mini Mono, based on John Finch Wildthing. The hull is 20" long and is powered by a 28mm 2600kV inrunner. This boat is a ton of fun! It handles great, and it's plenty fast on 3S (36mph). On 4S it's a missile, running 52mph.





I run this Mini Mono together with my sons, and it's a blast. I enjoy it so much, I started building another one, from carbon fiber:




I made a build series on the wooden version. You can find the 1st video here:


And here's some running footage!
