building my new model boat

AVGWarhawk · 01-06-12, 09:06 AM

I have my twin motors installed. These motors spin like mad! I might be a bit overpowered however I do not need to worry much about pushing a heavy boat around. These should do nicely! I'm pleased with the results. The screws spin opposite each other counter balancing the torque. She should fly!

what motors are these they look like 700 type

Titan 550 23 turn. Higher torque with more turns of the copper wiring. The 12 turn motors will spin faster but lower torque and burn up faster. However, your boat/vehicle will absolutely fly on the lower turn motors.

mine? No I don't think so its quite heavy

This will give you a idea of the size of these. Yep...I went overboard a bit! The smaller motor was in a Piper Cub RC (400 motor I think)

My model is getting heavy. The bulkheads are the larger plywood. The fiberglass and many coats of paint/resin have added a lot of weight. Just as well because I will have to add ballast so she sits in the water correctly. I will use lead shot for ballast.

That water was way too bright and blue -

So I had a quick play with 'shop -

Although the surface vessel is stupid to drop in such shallow water, and with little speed. Reminds me of Dover, December 1939, stupid people.

Sorry for not posting for a lot time now, I 've been busy.

A quick update: My motor now is a Graupner 700 BB Turbo, the lead baterries are gone and I have installed 50 (yes 50) lithium-ion.

Plus my shipyard is now relocated and renovated

Pics coming!

Nice boat

Looks like a great and time consuming hobby, i never got further than building Matchbox planes from wo2 when i was a kid. Maybe when i retire in the far future i will try to build something like this, where do you find the time?
