A couple of things I noticed on the Drawdio parts list --
1. C1 is listed as 630pF, but points to 18pF parts both for Mouser and Digikey. How about this one?
2. C3 for Mouser is linked to an axial cap. How about this one instead?
3. RA and RB both link to 10K Resistors.
BTW, I checked those parts because I'm ordering from Mouser anyway and wanted to try a flying setup to see how this thing works.
