Missing optional drawings

Hi,

I was looking through the forum and saw that there are many more "optional" drawings available than provided on (my) vans download page.

Is this correct? I am building an RV-10, should there be more available? There are also some Rotax 912 Plans in my downloads (would be a slightly undersized for the RV10 though...). I only have 17 drawings.

​

The attached PDF is a DIR dump of the OP files that were on the USB drive I got from Van's, many are non specific to RV10 but could be useful and/or applicable.

Ah yes, the mysterious OP files that I didn’t know existed until 8 years into my build.
