Radio installation plans

Some plans and ideas for the Noux mk2 radio installation. We are using a ca 116mm diameter food container lid and rim as the only deck hatch. We want the winch, batteries, servo, and Rx, all accessible through this hatch.

Update 2006 Aug 30: A variation on the same theme: a "flat-pack" version.

Ninja, a Marblehead by Henry Ericsson

A building guide for the "Ninja" Marblehead in 4 parts by Henry "Heffe" Ericcson. Published in Pienoismalli in 1988.

During the 80-ies it was still possbile to home-build a competitive Marblehead. The article describes the planking process, radio installation and rig building. An unknown number of these were built and raced in the 1990-ies, the most visible ones being two beautifully planked wooden Ninja's by the Purhonen brothers.

A nice example of how an article series can have a positive effect on the class in a country. A comprehensive guide starting from scratch building the hull and ending with tuning the boat and racing rules/tactics. We definitely need something similar for the IOM class ! (something along these lines is where I want to take the Noux concept - if and when I have time...)

This series later also appeared in the Swedish Allt om Hobby magazine. (If anyone has that article series I could publish it here also!)

Vimppeli, a Finnish model yacht from 1953

I've started a new 'Articles' section which will feature articles that I've collected. I expect they will be mostly radio sailing related, some in english, some in finnish or swedish.

This article, a piece of Finnish model yachting history published in a magazine called Joka Poika in 1953, is a plan and a building guide for a vane steered model yacht. At the end of the article an upcoming finnish championship with more than 20 of these boats taking part is described !

Thanks to Risto Tomminen for sending me this article. Risto had one of these boats and took part in the finnish championship in 1955.
