DIY GT30 mono outboard

Hi rc friends.
In this project, I tried to replicate as close as possible the GT30 mono racing hulls that look like this:

The project has already finished and the boat looks like this:

The construction of the hull is presented in the following video. At the description you can find the links for the construction of the outboard hatch, the driver, the boat cowl and the modifications I made to the tfl outboard.


The maiden run is here:

 
Very cool and unique design! Did you run it once so far? And do you have some plans to fine tune the boat, to improve the handling even more?
 
Thank you Jan.
Unfortunately only once. I hope for a 4s setup and a 3514 prop in the near future. I also want to trim up the outboard a little bit because the hull runs very wet. Finally, I may experiment with the angle of the turn fins... and I am wondering if the trim tabs are really necessary with the 3s setup.
 
I run a 4s this morning with exactly the same setup.
The hull sails surprising well. Even with a 4s it is still planted and stable.

I feel that it can handle even a bigger motor (e.g. a 2960 2700 kv).

Here is a short video:


Unfortunately I couldn't bring the boat close to the shore because there were logs and other obstacles.
 
Awesome! It runs so wel, it reminds me of ECO class boats. It turns great and the sound is nice as well. Great job [emoji106]

Maybe it could run a bit more loose, for even higher speed. But I like loose running boats, so it might be my personal preference [emoji6]
 
Thank you Jan. Yes, it can run a little bit more loose by trimming up the outboard. I might try it next time. :thumbsup:

Still I am not sure about the trim tabs. I should also try removing them.

Indeed, it runs so well that I was thinking of building another one with an inboard set up and different cowl.

As far as I ve seen some of the boats in the eco class have a similar triangular shape so this may play a role in sailing.
