| While I do not yet have an Aurora, this is what I have been using for the servo wheels on my 8717's: Horn Drill Gauge.

While it says Futaba on it, it works great on Jr servo wheels. You can drill from 12.5mm - 15mm. You are guaranteed that the holes will be 180 degrees from one another and perfectly aligned with the center of the servo wheel. You will also eliminate the need for any subtrim and don't have to rotate the servo wheel to find the hole that is closest to 90 degrees. Just put it on the servo wheel with the drill gauge holes at 90 degrees to the links and drill the holes for the balls. It is very easy and gets that perfect geometry on the servo wheels that we all want. At a cost of $5.00, it is well worth the money.
