Hartzell tests on Titan Engines.

Several have commented on my tests last week with MT Propeller on our Titan engines. I dug up some archive photos of Hartzells tests back in '07 on the 340, 360, and 370. I will be trying to get them back on the counter-weighted 371 and 409 variants after Oshkosh. Then hope to get Catto and Whirlwind into the mix before end of year. Lots of work but I think its worth it to sort out which props can take the HEAT! So far MT is the only one to certify their props on hp over 195hp....

Thanks for the pictures!

I don't know if Whirlwind has certified them, but their 2 blade 74RV is spec'd at 200hp+
