I hope I get some of this great service others have mentioned. I'm really looking forward to trying to compete in IMAC with ZDZ powered airplanes. I have invested in two 80 singles and a 160 twin. Neither of my 80 singles for my practice/out of season airplanes make near the power they are claimed to so I sent one of them to Showcase for evaluation. It's been there for 8 days so far. I've called twice to date to follow up on it but near as I can tell it has not been run yet. They said they are real busy. I hope that means they are selling engines, not fixing them. Anyway, I'm not complaining, only stating what I know...so far.
