Hi folks,
I had some questions regarding the AO-51, Delfi-C3 and other cardboard models.
AO-51 (75% scale):
Yes, it is available for download at: www.msig.ca/AO-51.html
Yes, it is available for free (if you like it please donate to AMSAT).
Delfi-C3:
It will be available at the Delfi team website @ TU Delft.
It is still a work in progress and I hope to have the prototype done in a few days. After that I will finish the pdf files for distribution.
Yes, as mentioned above, once it is available and you like it, please consider a donation to AMSAT.
Other models:
I might look at P3E at one point once it is launched and final photos and details are available. No, it will not be a 1:1 scale ;-)
Hope this helps,
As always, have fun and enjoy the hobby.
73, Stefan VE4NSA
