Hi Paul,
Thanks again for the nice comments. A bit of a blank few months in MB mag coming up as all my building seems to be centered around mechanical bits and pieces. (A bit like the Outboard motor I did in the Winter special)
Having read a lot on other forums, the question of Bow Thrusters and how to make them keeps coming up. So I have been designing a home made version, Twin rotors in one housing and brushless power!. Tests have been good and its powerful despite its apparent small size. Also been working on a new Racer model for club fun competitions and 'Have-a-go' boats for spectators. Hopefully get a few more youngsters involved in our branch of modelling. The new boat has been tested and goes well with only a few niggly design changes left to do. I can't say much as it will spoil the mag article, if it gets published OK. but its only 5 components!! and a 2 hour build, that should wet your appetite. This bit of Ron Rees madness also needed a look at making Vacuum Formers, so home-made plastic hulls and 'stuff' on the way.
All secret squirrel at the moment but good fun. Hope you have a go at Rhonnda, she's been out several times already this season. There's not a lot in the article on the keel weights needed or how to do it, It couldn't go in because of safety reasons and melting lead and pouring into a mold. With your planned scaled up version I should be looking at the local Church Roof if I were you!!!.
Cheers and happy boating.
Ron.
PS I think I answered your posts online, not sure now, if I didn't then sorry for the delay.
