Hello.
Thank's you Jeremy and Asmithnc.
I think AirBoats looks the best on grass and water.

We're presenting mounting for one or two accumulators.

Hello.
We were absent for long time. We still build AirBoats but slower than before. We just have no much time for models.
We just finnished our first test bench. We will test performance of propellers in electric and gas engines on it. These data will be used to build better AirBoats.

Now some pictures







Greetings to all AirBoat fans
Marek&Wojtek

Hello.
We focused on building classic Airboats. So now we're testing diffrent shapes of hulls. Airboat 5 was simple construction however AirBoat 7 has changed sides and front of hull. Bottom has been also changed but it is still flat.
On photos below you can see two Airboat7 hulls, ribs and bottom is the same in these two models, but one of these has been covered with balsa 3mm, and second linden-balsa plywood 3mm. The difference betwen weight of models is huge. We will see how it affect on controllability of models.







Weight of linden-balsa hull.

Weight of balsa hull.

Hello.
The weather crossed out our plans. We planned a few more tests but we couldn't did it.
The film is below.

Airboat hull must moves on water as flat as it must be possible, without unwanted slants

Hello everyone. don't
Before we'll present Airboat 7 made from laminate we're impressed of this video. It's very simple construction but runs very smoothly in driffts on water and grass. In addition to this it don't tilt in turns.

Second our passion are FSRs. In Poland it looks that:

Fantastic video footage!! Great work! Your airboats look fantastic as well! Do you build them for electric only or do you set them up for fueled engines as well?

Hello.
Our adventure with Airboats have been sterted some time ago from simple construction powered by electric engine but we've been made fuel Airboats as well- 7,5ccm ( nitro engine ) and 26ccm ( petrol engine ).
For some time we were building Airboats that they based on American constructions. Now we're designing and making our constructions. Airboat 7 is construction wchich we're still improving. Our goal is to build one construction that fit to electric and fuel engines ( max. 3ccm ).
Laminate construction of Airboat 7 will be tested on electric and fuel engines.

Hello.
Few days ago we moulded second bottom of the hull. It's 360g lighter than previous one without decreasing stiffness. We'll also add stringers ( is this correct name of longitudinal ribs ? ) to make the hull more stiffer.
