Rocky,
I was referring to the person with "full aft cyclic" and still dragging the pitot tube (on the nose of the aircraft) on the ground. Bob |

He was getting into dynamic rollover, and bottoming the collective might have helped, but I don't think more collective was going to do anything good here. Fortunately I wasn't in the cockpit, so I can't say for sure how much he pulled, or whether more or less would have helped. -- Regards, Stan |

Hi Larry:
The compensating weights are sticking up on metal bands that are about 1" wide and have square weights on the end. They are located on the forward upper right of the engine area and nearly directly above and behind the right seat. They are for easing the weight necessary for the collective/cyclic input. The thru bolts on them are hard to inspect except when they are removed. Not to throw a monkey wrench into the works but those weights you are describing are not used for collective/cyclic input. According to the Hiller manual they are for vibration dampening of the cyclic controls. "Vibration in the cyclic control system is dampened by two damper assemblies, ine installed on each upper firewall bellcrank. Weights on the damper assemblies are preadjusted to give the damper a natural frequency of 690 cpm +/- 10 cpm. Both rectangular and cylindrical weights are used. I believe the weights you are describing that pertain to the collective is the ballast assembly. This is located on top of the rotor head and has two curved arms that come down on opposite sides of the rotorhead. In the ends of these tubes weights can be inserted to provide the appropriate amount of 'pull' when actuating the collective and to adjust for collective stick 'creep'. |

Stan and Bob One time I had to take a farmer up in the Hiller to ID a field to spray. He was a really big guy - 6'6" and about 240#. We lifted off, went to the field and returned, no problem. There was another helicopter (Bell 47) working from a truck ahead of mine and he was sitting there taking on a load of chemical as we approached my spot. Well, as I began to flare to slow down, it didn't slow down and not much flare! I kept pulling aft cyclic and it was at the stops (I thought) when my pax said "Go around if you can..." and I pulled pitch and began a turn and climb to avoid the 47 sitting ahead of me. I glanced over at my pax and he was pushing himself up and back in the seat to give the cyclic more aft movement. Seems I had pulled the cyclic into his crotch during the flare and THAT is what limited the aft movement! We both got a chuckle out of that afterwards and I learned he was also a race pilot at the Nationals...... He was smart enough not to use the pedals to push himself back in the seat or we might have been on the NEWS AT 5. Rocky |

Stan & Bob It makes me think of a time when I had to take a farmer up in the Hiller to check a field for positive ID. He was a big guy at 6'6" and about 240#. We took off, checked the field, no problem. On return, there was a Bell 47 working ahead of me with his nurse rig on the ground, and as I began to flare, it wouldn't slow down. I pulled aft cyclic to what I thought were the stops and it kept going. My pax hollered "can you go around?" and I began doing so to avoid hitting the 47 at the same time. I pulled pitch and turned with room to spare and glanced over at my pax who was pushing himself farther back and up in the seat. Turns out the cyclic was jammed back into his crotch while I was trying to flare it out! We made a good landing the 2nd time around. Then I learned the guy was also a race pilot at the Nationals and had sense enough to keep his feet off the pedals while he pushed himself back in the seat. We got a chuckle out of that after the fact. It also taught me to not put any pax in the left seat when the duals were installed! Best Regards Rocky |

After reading the Hiller & the big farmer story, I thought I'd
relate something funny that happened to me. Last week I was doing a sightseeing tour over the reef. The pax in the left seat was a tiny little gal who was maybe 100 lbs wet. We'd been in the air for about 30 minutes and she seemed to be enjoying herself a lot, taking pictures and commenting on all the sea life. Well then it happened... we were about 100 ft off the water over the reef when she announces that she's going to throw up. I asked one of the pax in the back to hand a bag of some kind to her. They handed her the small gym bag I carry spare life vests and headsets in. I pulled her mic boom away from her face, and she went for it. On the first convulsion, she pushed the collective down. I'm used to that by now, because no matter how many times I tell people to stay away from it, they always seem to sit on it. Then she did something no one's ever done. With each convulsion forward she'd lean into the cyclic. She did it with such force that it surprised the hell out of me. You would of thought I was playing tug of war with a 220lb guy for how much force it took to hold the stick steady. The convulsions were so loud that she was breaking the squelch on MY mic. After about a minute of this she announced that she felt much better, and we all had a pretty good laugh. This might not sound all that scary, but I was pretty nervous about having an unpredictable spastic critter in the copilots seat (no matter how pretty).

one of the friend of a friend kind of story, reality to truth ?? not too far
off the pilot dropped two engineering summer students off near the top of a mountain to examine a communications shell for the day. after they departed and removed their equip, hunkered down behind a rock. pilot lifted off and established a circuit over the pax to make sure all was ok (no arms flailing to notify they left anything onboard - like all good pilots do) what he saw was the pax rolling around on the ground, obviously in some sort of distress, landed back at the same spot to find out what was wrong. what had happened was that these two bush greenhorns had thought that bear spray (pepper spray/mace) was applied like mosquito repellant, and suffered the consiquence !!

WHY would you leave the copilot controls installed when carrying a non-pilot passenger in that seat? What happened to you is the very reason I was told that you want to ALWAYS remove controls unless the person sitting in that seat is qualified to use them. -- J Dana Eckart, PhD, PP-RH, KA4EVL | People who think that life couldn't be Virginia Bioinformatics Institute | better lack vision, and those who think | it couldn't be worse lack imagination. |
