(WOF) F1 tunnel hull building report

Looking great Glassing takes quite some time, but after the first flip, you will be thankfull you did it!

By the way, do you have a speed number in mind as a goal to reach, or do you focus on good handling / cornering?

 

Thank you Jan
!
Yes, I definitely want a speed > 80 kmh.
I am determined to do whatever it takes to surpass this speed target even a 40 motor with 6s.

The hull seems quite strong and I want to push it hard
.

 

That's the spirit . With your 3674 2200kV motor on 4S you should be able to reach 70+ or even 80km/h already. On 5S you should crack the 80km/h easily and probably 90+ km/h.

Of course depending on many factors, but looking at your hull and the dimensions you used, I think it will be a great performer.

 

Oh thank you for your encouraging words. Jan!
The starting point will be a 5s and 40mm 1.4 propeller and then we see.

 

Finally the outboard with its cover is on the hull...

 

It looks awesome Great design and build. I'm very curious to see how she runs.

 

Thanks Jan !
I am also so curious about her performance but I have to be patient!

 

Wow ,I love it
Super build ,caint wait to see it run .

 

Thanks Alex!!
I also believe that it came out nicely!
If everything goes as planned she should run in May-June

 

I don't know how big your engine hood is
but maybe i have something for you










gr jan ilmer

 

Wow excellent design and would probably fit my outboard.
If I didn't like so much to build I would certainly consider it!
Thank you for letting me know!

 

Goodmorning rc friends!
I ended up using 160gr/m2 cf and
50 gr fiberglass to strengthen the cowl and the nose of the hull.

I feel that the hull is much safer now.

 

Nice job! It looks like you left a glass surface at the top of the cowl for rx and gps signal .
Did you decide the paint scheme yet?

 

Thanks Jan.
Indeed, the GPS must have strong signal to capture the ultra high speeds of the hull...just kidding !
Regarding the colors I have decided silver, white, fluorescent orange and black and I also have something in mind for the painting scheme like this:

or this


Currently I repaint the Penarib since the temperatures have risen recently.

 

I stripped off the inner construction of the cowl and I enhanced it with 100 gr/m2 fiberglass. The part without carbon fiber was further enhanced with 4 pieces of thick fiberglass tape. The cowl weighs 195 gr but it is quite strong.
Overall, I am very happy with the the result in spite of some inevitable imperfections that must be improved.









And the imperfections...

 

It looks great, I like the side flanges on the nose cone and cowl . 195gram sounds good. It better be strong than very light!

 

Looks better and better .
Really cool to see you build this boat

 

Thank you very much guys.
I really enjoy this project.
I agree Jan better to build strong and experiment with more volts or bigger motors to achieve your speed targets!

 

Fiberglassing the hull....




I also sanded the cowl + putty. The cowl still needs so much work


I fillet the corners with thicken epoxy. The cloth at the top is one piece... Very happy for this.


After trimming and initial sanding...

 

This is your best built so far, in my opinion. Quite complex but the result so far looks great.
