I started collecting and rescaling existing (free download) models into 1:87, mostly aircraft, but also some cars. The collection so far is here:

The link takes you to the end of the thread, where you can see the latest additions. Work yourself backwards towards the beginning. The text is in English.

I hope you find something useful. If nothing else, you should get some tips on how to rearrange parts sheets when rescaling.

Happy holidays, Leif

PS. Now I see that Gil & John have already supplied this link. Sorry... and thanks!

Leif............. I hope you don't mind that I posted it. This really is a wonder thread and I enjoyed it very much.

Are you still working with the tiny motors and batteries?

more exersizes in scaling

As Larry says - the math is very simple to downscale models to HO (1:87) scale:

source scale / target scale = scale factor

scaling 1/33 to 1/87 is:
33/87 = .37 (that means set the print scale to 37%)

scaling 1/48 to 1/87 is:
48/87 = .55 (set the print scale to 55%)

scaling 1/72 to 1/87 is:
72/87 = .83 (set the print scale to 83%)

Thanks for pointing out my inadequacies in math. I still prefer to use a nice little interface program to do it for me... Not likely I will ever commit that formula to memory since I have a program that does it for me.
