Hi All,
Assuming a Continental TSIO-550 engine, MT Propeller
recommends their four blade propeller.
1. & 2.) The climb and cruise performance should be slightly better
with the MT Propeller since each application is a custom designed propeller
blade.
3.) MT Propeller have electric de-ice boots.
4.) The four blade MTV-14 propeller and spinner assembly weighs about
53 pounds.
The counterweighted blade MTV-14 propeller and spinner assembly weighs
about 69 pounds.
(These are estimates based on the weight of a MTV-14 for a Lycoming
IO-540 engine.)
5.) MT Propeller recommends the counterweighted blade configuration.
In the event of oil pressure loss, the propeller blades go to a coarse pitch
setting. This reduces the propeller drag almost as much as a feathering
propeller, without the flight hazard of a feathering propeller.
(I'm wearing my flame suit on this one, since I understand a fearthering
propeller is the current "correct" propeller configuration on this list.)

I have read a lot of the LML past posts but would
appreciate a current discussion including the following variables. What
prop wins the "overall" competition on the IV-P: 1. Climb
performance. 2. Cruise performance. 3. De-ice (electrical or
fluid?) 4. IV-P's tends to be aft CG (Is heavy or light best?)
5. Full feathering. Competitors....AeroComposites, Hartzell and MT.
Finally, any input on source of prop de-ice
package would be welcomed.
