Just a really quick update... the Gil battery I had in the plane failed after only 2 years. I was able to replace the battery with a Concorde and was able to get it installed this past week.
We put about 2 and a half hours on her this week and the plane is running stronger than ever. I've been really impressed with the new battery so far. The Concorde battery is the same battery we use in Tinker Belle and they've held up very well. I'm hoping my little 140 will run for many years on the new battery.
