I think we can all agree that the guy who so elegantly pulls off the nomex flight suit / flip-flop combination is a very creative fabulist.

Rainer took me on a practice run and did the display, the only thing he mentioned that was special was to always check the TRGB oil levels and top it up as it bled out under negative G.

Chuck Aaron was quoted as saying the fuel system was modified to cater for inverted flight.

I see it has a g-meter - is that standard or only fitted to the display aircraft?

when i first saw that video of those claims, i knew he was a prima donna showboater. The mustache should have been a dead giveaway. And I laughed to myself at his ignorance to the industry professionals that would sure out him as a joke.
I have no respect for him other than he pulls off some nice manoeuvres most wouldn't do in an aircraft more than capable of doing it with or without him.
Bravo Chuck.

The gauge with the green/yellow/red markings? Yes, its called a mast moment indicator............and i worked on 16 different S/N BO105's and it was fitted to all of them.......

i think he is referering to the one 2 up, with the -2 to +5 range

Mast moment has nothing to do with the g-load pulled.

High mast moments usually happen when in contact with the ground (e.g. slope landings or harsh checks of the cyclic when doing the hydraulics checks before T/O).

Thats absolutly right, MM is an indicator for bending the Rotormast, not the load carried

However: as you said here, Flying Bull:


You can also exceed the MMI-limit recovering from a dive - with a high power setting - important to know, when playing with the helicopter.
Better to reduce the collective, before pullong out and appling it then again - less stress for the mast and no lights ;-)
Which was the point I was intending with my comment about the picture and the MMI being so low


EDML, same point applies.

Not as a Mod; rumour has it that Chuck had a T/R failure at a very low height this week. No one hurt, wait for more details.

I worked with the LS version for 5 years and confirm all he describes is standard build. Transmission is mounted to the helicopter floor by 4 struts about 1 m long ( if i think long enough I may remember the part number 105-1xxxxxx4. I cannot think of any other way that transmission could be secured to the deck .

I think Ziggy Hoffman may have been the first to demonstrate the rolls and loops .

Also If i recall correctly neither the gearbox nor driveshaft were titanium . The rotor head was and was a work of art IMHO
