So, this is my third CAD rendition in this 'vintage trilogy', before I go and explore other model building avenues. It's was a popular (in it's day) trainer & sport flyer, designed by David Boddington, and published free with RCM&E March 1970. As I said somewhere else on this here forum, it was really the first radio control model I had any kind of success with, I think I may have had a two channel Macgregor radio setup, after a little internet browsing, I think it was this:
As I had it new for my birthday, it was pretty reliable, unlike every other bit of radio kit I had before it, like this for instance:
I reiterate, theses are pics from the internet, not my actual hardware, which I asume no longer exists, except perhaps on a molecular level. It does look like they have become collectors items, which is perhaps safer all round!? Ah! The memories! I still recall the patterns on the box, even the smell of it! All in it's pristine brand-newness, my ticket to RC heaven, which it was. I think the batteries were it's main achilles heel, forever needing to be replaced, with no real rechargeable option to hand. I loved that brushed aluminium, so cool!
Anyhow, enough reminiscence! Here's the basic fuselage config, with the cutting sheets to follow;
Two of the fuselage 'formers' are constructed of pieces of 1/8th balsa, simple really, but I thought, in for a penny...
Now I have included the former parts on the 1/8th cutting sheet too. ;-)
Here are the jpeg's of the finished CAD files, which I'll upload to Dropbox as soon as I am finished with them.
By the way, if you think getting a laser to cut out all the parts is taking the fun out of model aircraft building, or in some way cheating, then you're probably on the wrong forum!
Seriously though, I did consider this, but after my Sharkface second cut, I had to trim some balsa by hand, and just remembered how hard it is to do! The upshot for me is that there is still bags of fun left after this cutting process, both in the assembly and flying of the finished model.
P.S, and think how many scalpel blades you'll save!
