Catchalot

I made a Cachalot at the time with an ED Racer.

I was very disappointed as it was slower than my semI scale torpedo boat based on a scaled down Black Marauder by Philip Connolley, such a great performer that I went on to fit a K&B35, then an OS40FSR.

Maybe I just did not understand a deep Vee.

Good luck

Thanks a lot Alan, that certainly gives me some idea of where to start.

All comments appreciated, so if anyone else has some experience to offer all contributions welcome !

The Catchalot is 32" and if made of ply will be a bit on the heavy side, so you may have to try a few things. This might be a start, 14.8 lipo perhaps made up of two 7.4 depending on the room and layout of the boat, an outrunner of between 1500rpv to 2000rpv with 600w, water cooled ESC to suit. for the props I would buy a few different sized plastic ones as they are cheap and you can work your way up from a 35 mm two blade.
I would put the motor where it is shown on the drawing with the ESC close by it, then you can move the batteries about till you get the boat to sit right.

These are just my ideas, others my know better

After more years than I care to remember building and flying model aircraft I am venturing Into model boats, and of course have many questions.

I've had plans for Vic Smeed's 2.5cc sized power boat Catchalot for many years and thought I'd start with that, on the basis that all of Vic's aircraft fly well and so his boats are likely to be as good for a beginner !

I have quite a lot of experience of brushless outrunners In my aircraft, but have no Idea what motor/prop/LiPo set-up to use... So all advice would be appreciated, as due to noise considerations electrics would be preferred.

Similarly, Is the "sit" of hull on the water to be considered, In so far as the positioning of the gear ?

All comments/advice would be appreciated.
