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

 

[Dirk Jan Cozy]

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:

 

[Dirk Jan Cozy]

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!

 

[Justin "BeaVe" BeVier]

i found your youtube channel a few days ago, i'm a gas guy, but i'm going to have to build one of those mini mono's. do you also have plans for that mini hydro?
