RE: ACE R/C 4-40
Og,
I know the feeling about getting 'distracted' from RC. I have planes in my shop that were started as much as 10 yrs ago, and never finished. Your bipe project sounds like a nice way to come back. I have 2 91 Surpasses, one that I swear is held together with blue RTV silicon, and they both are the best engines I ever had.
