My A&P used TGH to exchange a turn coordinator in my 2003 Cessna 172 SP in April, 2016. At $715, the unit was a little pricey, but not overly so. The unit was bad out of the box. It spent several minutes erecting and made a terrible mechanical noise in the gyros. It was sent back in June under warranty. The unit that replaced it erected a little more quickly, but still quite slowly. It also made the same awful grinding noise. It was sent back in August, again under warranty. This final unit appears to operating correctly, but I don't have great faith in TGH's workmanship at this point.
The five month saga of my overhauled turn coordinator from TGH looks like it might actually be over. This part ended up costing me $580 in labor to swap the bad units that TGH did NOT cover. It also cost me significant downtime on my aircraft and damaged the trust in my aircraft from the folks who rent my plane. However, I did give two stars instead of one because the warranty was honored. read more
