Yes you got it right. It will (should) be amphibious however at the moment as i'm only 14 i'm findng thast getting my parents to part with the money is harder than actually building it. But eventually it will have GRP hull, BB deck gun, r/c torpedo, compressed air missiles and two piston ballast tanks as well as working sounds and lights.
You are doing fine. Take no notice of us sill old men. It is an admirable project, and probably in advance of what a great many folk would undertake. I hope the family come across with a substantial Christmas box to enable progress.
Out of shear curiosity - do you get any encouragement from your school. Is there perhaps a model club or similar? Do you belong, maybe to an outside model club?
If it wasn't for my school i wouldn't be able to do this. They have a huge technology dept. with lathes, milling machines, bandsaws etc. and a load of materials. At the moment I'm going there everyday.
They do have a Radio Control Club however it is mainly for cars, and only runs and when i had my r/c boat i did belong to an external club. The only problem is that there arn't many, if any r/c clubs for subs in the uk and dealers for parts are even rarer. This is mainly why I've decided to scratch build it.
At the moment I've started on the GRP hull and ballast tanks however the speed at the moment isn't really worth telling anyone about, but when i do pick up speed i'll let you know and try, TRY, to post pictures (depending if i can persuade my brother to lend me his digital camera)
There are model submariners in the UK and at least one active club/group. There are always seems to be a small but very good specialist display at the Donnington show and the London show (the one that that was at Wembley but this year will be at Alexandra Palace). Also, and very important from your point of view, there always seems to be at least one knowledgeable person on the stand. The dates are 21st,
22nd & 23rd January 2005.
I suggest that you try your best to get to 'Alley Pally' in January and preferably take brother's camera along too.
