Hi there,

I am returning to model boat building after 35 years and am finding the changes in technology somewhat of a challenge.

My first project is a Tarpon, a 35 inch cabin cruiser from the MyHobbyStore plans. So far I have built the stand, hull (round bilge - planked in 2 x 10mm lime) and part of the superstructure, but am failing to understand how to choose the right electric power plant and how to judge what ESC to use with which motor.

I am hoping to learn all of this from the forum, as well as how to do everything better. Hopefully I will be able to make some contribution to others as time goes on.

Good Boating!

welcome to the forum, Rosy and especially from Canberra.

I guess it will have changed a lot since I taught there at Campbell High School.

I still go onto google earth and look up my old house in Scullin..brings back great memories, lol.

there are a lot more knowledgeable members than me on this site regarding motors esc's etc, but enjoy having a look around and have a look at the electronics section...a wealth of info there.

Not sure if u want to use a brushless and lipo setup with this boat...

So will only suggest a LA (lead acid battery) setup.

Going with a single prop 40mm should do ... either 2 or 3 blade, up to you.

A single motor, 600 or 700 size should get you onto a  nice plane.

A 20Amp rated esc

And a 12V 3Ah battery should give you around 45 mins to an hour of run time  but you can use a 12v 7Ah if you have a deep v hull and the boat can handle the extra weight.

I have suggested 12v to go with the 12V rated motors but you can run at 6v if desired , but the boat will be less powerful and may struggle to get up on the plane.
