Oshkosh helicopters by Stu Fields
Well there was a tip jet (70% H202) ship there with one pilot with 20 min and a reported other pilot with a few hundred hours... Sikorsky had a battery powered 269 on display with a duration spec of 15 min. Safaris, Rotorways and Mosquitos and Larry Neals Butterfly wrapped up the rotor craft.

Undersling and 2/rev by Stu Fields
If an over weight pilot exceeds the recommended seat weight of his helicopter, will this affect undersling enough to cause an increase in the 2/rev vibration??? Does increasing G forces cause an increase in 2/rev?? Stu

New coinage by Stu Fields
I've coined a new acronym that stands for a principle often used in the experimental helicopter community. I have named it NHFY. It stands for None Have Failed Yet. It is a reliability measurement used by some that certainly needs close examination to ascertain the validity. Some folks who...

credibiltiy by Stu Fields
It seems that if there are two possible causes for a helicopter accident, the preferred one for the manufacturer is the one for which they have no fault. That certainly is the best for them. However, lets say that a low hour helicopter suffers a failure directly attibutable to fatigue. ...

Piasecki crash by Stu Fields
Just got word of a Piasecki crash that involved Joe Pike and to other people who were on board. Joe had re-stored the twin rotor ship. Initial data seems to indicate an engine failure with the ship hitting power lines and burning. Joe was an outstanding wrench and pilot. Joe did a BFR for me...

PHOTOS: Rotorfest and PHL - October 04, 2009 Over 100 photos in this group. The highlight at Rotorfest for me was the Kaman K-Max and the Pilatus Porter jump plane. The clouds moved in briefly in the AM and gave us a short-lived scare, but they burned off. Plenty of copters and GA aircraft,...
