A hangar neighbor has a Velocity with a 13b with a Ross re-drive. 25 year old project that is licensed and flew once. He's 85 years young now and trying to revive the project. Newly rebuilt engine. He seems confused about lubricating the Ross drive and wanted to fill it with oil. I convinced him to feed engine oil with a 1/16" restrictor to the top and add a drain line from the bottom. Currently that is 1/4" id hose. Will this work? He is concerned about blowing out the seals, as he had that problem initially, and that led him to remove the feed line for a time. Can't find the documentation from Ross.

BTW, this aircraft is planned to be put up for sale soon. Anyone interested?

Thanks for any help,

If the drain is large enough there should be no pressure build up to blow the seals.
The temperature is anther matter so use Teflon seals. Part 10.
