My forward CG is because it is an '02. All the pre-2004 DA40's are like this. No ballast to remove. I have an MT, which is 16 lb. lighter than the Hartzell I believe the F.A.T. STC requires. Hence the additional 34 lb, all in front of the nosewheel.BRS wrote: ↑Wed May 01, 2019 10:41 pmRich,
I'm not sure I understand how you figure the above. Here is how I understand it.
-If you have a later plane with the ballast bolted to the engine, remove it and install the supercharger. Almost identical weights.
-If you have the plane w/o the ballast, then just bolt on the supercharger and adjust w&b. This is my configuration.
I'm not sure why you would need to change your prop. Which one do you have? I had changed my prop because I wanted the PowerFlow exhaust. The original prop was not approved with the PowerFlow, but they were the same weight. Do you have an MT?
BTW the non-PF Hartzell is about 3 lb lighter than the one allowed with the PF.
