Since air testing my replacement tank in the home office, I moved it back to the shop; removed the gasketed cover and reinstalled it with proseal (no gasket) and left it to cure for a couple days. Lo and Behold, we had a snow storm followed by an ice storm. We lost power for 5 days (no heat to help the curing process). Proseal never cured; and remained a gooey mess.
I did get some wiring started on the roll servo in the right wing. I also removed the left tank cover; cleaned it all up and re-sealed with proseal.
