I run -20s in my U206 jump planes. 289 lbs. Running them at 650-660 ITT they should last forever. I use the Cool start relay pack for 500c starts. Wish there was a lighter prop than the HC-B3 that wasnt so expensive.
My thoughts exactly. The human race is brilliant at re-inventing the wheel. Take the Max Holste Broussard. Just about a twin fin copy of the de Havilland Beaver which first flew about 5 years earlier. I think the French ministry of defence only asked for the design so that they had a French built machine. They probably only came to that decision after they'd seen how capable the few bBeavers they had were.
