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.

Have a project that needs 6 blades from the J-2. The blades need to be in flyable condition for the restoration of a rare McCullough tandem rotor helicopter. Any clues out there????

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. ...

I'm selling my Safari $70K. If interested call (760) 377 4478 for a bunch of extras.

I'm looking for a used copy of Ray Prouty's More Helicopter Aerodynamics. Also for the copy titled Even More Helicopter Aerodynamics. These issues are required for a research project I'm doing for the Experimental Helo magazine. Thanks

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

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...

POLTF: Problems Obvious to the Least Tutored in the Field. This is to be used with NHFY: None Have Failed Yet. NHFY is an industry accepted response to POLTF

The Golden West Airshow (June 12-14) is scheduled to see several homebuilt helicopters. Expected are Mosquito, Rotorway, Safari, Helicycle and possibly an Ultrasport. Good x-section. The Experimental Helo Magazine will have a booth... stu

Just completed checking the wheels of 84 Surplus Solar T-62 turbine engine sets of wheels for cracks. Only found two turbine wheels with small cracks. No cracks found in the compressor wheels. These engines seem to be quite sturdy. We started several and looked at vibration levels with a...

I've got my copy of what turns out to be a MUST HAVE addition to the Volume I work of the same title. Few people can write clearly about a technical subject like helicopters without using a lot of mathematics. Ray Prouty has a real knack... I'm jealous.... see ...

The Safari near Phoenix that crashed with the loss of two lives is now followed by a RotorWay in Vermont flown by Ronald York that crashed resulting in the Death of Mr. York. The investigation of both accidents is pending.

I finally got a few (15) minutes in a turbocharged Enstrom. Controls heavier than what I'm used to. CHT issue at 4500' two up and 65F Overboost light while hovering Vibration level felt a bit more than my two blade Safari Auto very nice. No VSI but it looked a lot nicer than the...

Well, advancing age brings with it some clear thinking and some not so clear. I have purchased a Helicycle Kit and still own my Baby Belle. People with more than one helicopter that aren't in some commercial business are at least suspect. My wife is probably just patiently waiting for me to...

Recently there was an accident with a very low time (3hr TT)RotorWay helicopter being piloted by a high time RotorWay experienced instructor and the owner a commercial rated helo pilot. They were hovering at a 3' level with the owner at the controls when it snapped rolled to the left so hard...

A report in of a Helicycle climbing at 600fpm at a density altitude of 8,000. Of course the passenger capacity is limited to only 6 politicians with the lies removed.

FAR 91.409 involves itself with requiring some sort of special inspection program for turbine powered rotorcraft. Builders of Amateur Built turbine powered rotorcraft are being forced to generate some inspection program documentation to get the airworthiness certificate. Nearly all of these...

I've acquired an HA-6 Carburetor part # 10-5045. I would like use it to replace the updraft carb on my 0320-D2J that is mounted vertically in my Safari. Is there a manual covering this carburetor? Does it require a fuel pump? Stu Fields Safari driver
