On to the rotor head. I messed up this part pretty good. I originally didn't cut out the center section of the rotor head disks. They need to be cut out to allow the main rotor shaft to extend all the way from the bottom of the transmission bucket to the botom of the rotor head. But that's the reason for this thread. I mess up so you don't have to.
I added some cardboard to the bottom disk to make it sturdier. I also moved it up the main rotor shaft to be level with the exterior of the fuselage. This hides the transmission bucket better, and makes the disk look like the swash plate. I decided to use some carbon fiber rods to reinforce the main rotor blades to keep them from drooping. The carbon rods are superglued to the top of the rotor blades, then the blades are folded and glued together at the trailing edge. They seem pretty rigid now, we will have to see how they age. The rotor rotates freely as designed. It looks like I'm out of parts, so the helicopter must be complete. I will get some glamour shots and call this project done. I hope the photos of this build will help others in constructing their Black/Fire/Jay/Pave/Sea/White/Stealth Hawks. I think I will work on the Firehawk next. |

ALERT! ALERT! Launch the Jollies. (Jolly is the call sign of USAF MH-60's. A continuation of the Jolly Green Giant (HH-3) of Viet Nam heritage.)

Man, I hate rotor droop. Sorry, but I had the photo booth set up and couldn't resist.

Nice bird knife, I'll have to give that one a try.

Knife, very good tutorial to build the hawk. To prevent rotor blades drooping, what I do is separate the blades from the helo. When making the blades, I sandwich a wire in each blade to ensure no easy drooping. When not it use, overturn the blades and lay them flat until display. This way, you can keep the blades in good shape. Well, that's my two-cent.

Darn autospelling corrector. Motto of the USAF rescue services is "These things we do, so others may live."
Thanks for the kind words, MacSongLi. Thanks to nikischutt, who did the original builds on Murph's H-60 fleet. For papermate, the wire suggestion isn't bad, but I think the carbon fiber rods will stay straight for a long long time. I got them from an old RC model (a Vapor) and they were bent in a circle for several years. As soon as I cut them out, they snapped back straight as an arrow. It was also suggested to me to use the metal straps out of some file holders. I would have tried that, but I had the carbon fiber tubes on hand, and the rotor hub was just a little too narrow for the metal straps. This is an experiment. I'm giving the model to the USO, so it may be on public display for several years without a chance for me to rebend the rotor blades. |

Knife, you're putting me into a helo mood now... darn it.
Great builds, I love your fleet, and really appreciate the build thread and tips. Gary

Here's the Pave Hawk in its final home, the local USO. It's escorted by two of Murphy's T-28 Trojans. I should have made a stand for the Pave Hawk since it sits so low. The Fire Hawk build has started, will post photos once it's finished.
