So this has been in the works the last few months and with all the supply chain issues I have been waiting on parts but have been promised last one will be here next week. My 4 is currently setup with an O-360 A1A with a 72 x 87 Sensenich metal prop. I have always wanted to have a constant speed as I loved the extra capabilities it gives you. My previous plane was a Comanche 260 so was definitely spoiled with that.
Well I didn't want the weight penalty of a CS prop as I have worked hard putting my 4 on a diet and shaving over 20 pounds off of her since i got it. So I finally bit the bullet and got a whirlwind 3 blade CS. doing the basic math I should break even on the weight and with how much lighter my wallet is I should be way faster!!!!!
I plan to go up and do some basic Performance testing before I take her down to start the conversion and then repeat those tests afterwards and get some real world data. Can't wait to share the results with you guys
