I know, it is not a beauty. It is just an easy way to enlarge the boat

to make it big enough to carry the strong and heavy outrunner motor which I use for my airplane

I simply printed a 100 mm extension and daubed it between bow and stern part - with tape as usual ;-)
At first I tried a 35 mm surface propeller which I got from a friend. This Propeller is more effective than my printed propeller. It needs less motor speed and was hardly to control because it pushes strong even with little throttle. So later I preferred the printed propeller. It is not so wild and makes more noise due to the higher motor speed ;-).
With increasing speed, the bow shoots up and throws a large bow wave which easily can splash water into the boat. To hold the bow low it was necessary to shift the weight forward. In the end even as much as possible.
Sorry for the bad video quality.
I uploaded it twice with different size but it doesn't make any difference. Partly it is highly compressed.
