Greetings all. This is my first post here! First I want to say thanks to Darth for making some great bodies. This HH-60 is my 3rd of his. My first was a bell 222-UT on a Trex that I did up as a Coast Guard heli (which looks real sleek), second was a Kiowa Warrior on a blade cp, and now the Jayhawk. In fact I've only been flying heli's for really about a year. Im forseeing that that blade might just have too turn into a Dauphine.
Anyway as far as the setup. I have to say that this heli was a good challenge for me. It's unfortunate that more heli manufacturers dont see that all the really cool new helis are low boom with raised tail mechanics. And finding raised mechanics for the Trex was a real p.i.a. . Most of the places I attempted to contact didnt respond. I weighed the options of belt drive and electric and figured due to simplicity to go with an electric tail. This heli is a straight up Trex 450 SA with the align motor and speed control combo. I went with the SA because of affordability and the nice flat panels to bolt to. I relocated the boom to be much lower on the frame by using two hobby grade plywood plates bolted to the frame and sandwiching the stock boom block. The drive shaft for the belt remains in there but the belt is obviously gone. I used the stock boom and then made an extension with a wooden dowel that bolts into the tail. Attached to the extension is another wooden dowel rise and to that a plywood mounting plate for the tail motor. I was aiming for symplicity and affordabilitly (helis and affordabilty just dont sem to go well together). Eventually I could see using carbon fiber sheet for the subplates. The tail rotor is run with an Eflite park 370outrunner brushless motor and an Eflite 10A speed control. I am using also the Align Gyro. The prop on the back is a 7" slow flyer prop. I built a Basswood subframe that bolts to the bottom main chassis that attaches to the body and holds the landing gear. The lights are from Maxxlights and are powered by a 4 pack of AAA batteries. Balancing this thing was a real challenge. It is very heavy and im afraid to see what its actual weight is. The test flight with it naked was amazing. I could not believe how stable and hover friendly this is with that tail for a first. Much better than I had expected. The test with the full fuselage want more challenging and hands on. This thing is tail heavy for sure. But I know with some refinement (and a less windy day) I can improve it. I literally finished the body yesterday and now I have some wiring cleanup. I'm hoping to get some in flight pictures this weekend. I do have a small video that I will have to find a way to post on here showing the navigation lights and beacons. The body Darth made is great. It did take some good modification as his is the special ops style the the exhaust diffuser and IR jammer and I needed the navy variant. I was able to find great pics on airliners.net plus I have a friend stationed in Kodiak that got me a couple really nice photos to work with and this model is based on one stationed at that base. So.. I will make sure i get some flying pics on here and when im feeling brave (yikes) Id like to get some pics over water hanging a Gijoe diver. I "borrowed" my sons navy diver and hung him off the 222UT one day and it looked pretty cool  Anyway thanks for reading my rant and good luck with your heli's. Next up.. hmm maybe a Eurocopter Tiger?
