There is a very negative thread over on the CPA board about MT propellers. Most of it deals with the U.S. distributor that holds the 210 STC. There is also quite a bit of frustration voiced by those who have them regarding service. It seems that the blades can only be overhauled in Germany and it is taking 3-4 months.
This might just be a 210 thing, I’m not sure.
MT props have been taking a lot of heat in the experimental community too over this service issue. They are liked for the performance on experimentals, but people are getting angry over the shipping to Germany, which is expensive, and the long time. I have heard of up to 6 months. So its not just a 210 thing, although the STC holder might be aggravating the situation too (I don’t know).
I wanted a composite prop for my RV7 and doing the research decided MT was not for me. I ended up with an ACI.
