----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]---- I had an Aeromatic prop on my coupe for about a
year. I bought it at a flea market and sent
it to Aeropropellor for overhaul. I ended up spending about $2400
total. While it allowed the engine to spin up to a higher static RPM I did
not notice a big performance increase. I maybe got off the ground a bit
faster but top speed was slower. Also the adjusting weights needed to be
rebalanced when the weather changed, it seemed fairly temperature
sensitive. I decided to give it up when one of the blades (which are made
of wood and held in by large lag screws) came loose. I sent it back for
repair (another $400) and then donated it to the EAA museum.
I feel more
comfortable with a nice solid metal prop. I would go for an O-200 upgrade
to get better performance instead.
