I have the struts nearly finished. The bottom ferule needs to be shortened to a point slightly ahead of the strut faring and two steps will be made out of 1/4" brass tubing and attached or soldered to the front struts. These will be a lot more scale looking than the previous struts and I will also be making up an upper faring that will butt up against the body. The body has all repairs done and the cockpit is gutted, less the back wall. That is not possible to remove as it would destroy the canopy structure. I may weight it up to 17 pounds or just move the batteries forward to balance the heli as is, which may make it a bit easier to use as an auto-rotation trainer. I am really looking forward to this version and the final one later next year. Take care.

looking great! i too am working on a Funkey 600 size 500E and have paid very particularly close attention to the landing gear. i promised myself after the last one i built that i was gonna do some very different things to the landing gear setup. For me, the landing gear makes the heli in many cases.drive a rotary, fly a rotorcraft

Thanks. This one will have a very different look to it once the gear is finished. I have thought of ways to make the gear spread on landing and then I keep coming back to look at the spot the gear on the model exits the body. It's not going to happen that easy and yet have access to the mechanism for repairs or maintenance. I now have the struts installed and there is a lot more work yet. I will need to make a close fitting rub plate for the top of the strut to sit against. There is also an upper faring to be made out of styrene and then screwed onto the strut. I am trying to put this together as realistically as I can because the original struts are so awful compared to the real McCoy. I will save all that specialty work for the new body, not for this one but I might give it a shot so I can verify that it will work. For now, I just want to get this back up in the air. Take care and hope to see you at Dalton.

The struts are pretty much done now except for detailing that will be put on them once they go into the new body kit. These are a far cry from the factory struts and the last picture shows how much of an alteration was done to them. It is time consuming to make up the sets but once it is done, I hope to not need any backups and at least one set will stay with the old body. Its fate is not yet etched in stone. Every day I am going over changes in my mind that can make it hard to tell that this is not a museum scale helicopter. I love the challenge of scratch building parts for this build and doing it over gives me a chance to make things differently. Take care.

Wow Don, awesome work!.

I need to make a set for my fuse as it looks like no one want it. I have a R50 I got from my buddy here and will probably shoehorn it in!!!

Love your attention to detail. I wish I had the patience to get that nice of results.

That is some really nice work Don. Definitely a big improvement over the stock struts. One question, is there a way to run wires down the struts for the position lights at the tips of the skids?

what I did for the lights on mine was I ran the wire from the fuselage, down the front strut tube and then into the skid through a small hole I drilled into the skid tube just in front of where the front strut goes into the skid. from there it goes up to the tip of the skid tube. the strut is then covered by the fairings I make from construction paper to hide the wires going down the struts

Good looking gear Emile. Do you do anything to the construction paper to stiffen it up or make it more durable?

I laminate it in two layers, then prime and paint it. strengthening it more than that isn't really necessary since it isn't load bearing, its basically just along for the ride.
on the one I am doing now. the skids "squat" like it does on the fullsize, really cool looking.

Those gear do look really good. As to mine for the wire, the rear strut has a channel that goes down the front which is covered by the brass tubing and that tubing becomes the way to close the channel. The front of the ferule for the skid is slotted to allow the wire to be fed into a hole in the skid. As the strut is installed on the skid, the wire is fed up the strut and then the hold is covered by the ferule. Last time, I cut the channel, glued the wire in place, then covered it with JB Weld but this time, all I need to do is to feed the wires down the front when I am ready to redo them. Just a bit more work and this is back in the air as an auto-rotation trainer. With the snow now coming down, it may be into the new year before I get this off the ground as I don't have any place this season to give it a test hover. Southern Tennessee is looking better all the time. Take care.

Don

PS: Sorry, Emile, but there is some beautiful land around Pulaski that I would love to find a nice house on in my price range. No slight against Alabama.

I found the answer to a question I had posed by going back and relooking at the pictures.

The struts look better on the bird than they do apart from it. I wish that there was a simple method to make the gear work as the original or if mine were able to squat, they would be on the money. The body only sits about 3/8" higher than perfect scale for the standard skid height. At rest, the body of the full size 500 is supposed to be about 8" clear of the ground. Looking at shots of them, you ask yourself, how is that possible that it is only 8" clear??? Here are some pictures of the gear installed. They were worth the effort.

It is ready for flight. Now, I need some good weather so I can get out and practice autorotation landings until I can do them blindfolded. Um, ok, not blindfolded. They are way to easy on the simulator but after finding out that the chassis floated like a butterfly, I figured I better get at them. I loved how the head now resembles the full size even down to the small amount of the shaft showing before the head. I started off with 71mm turnbuckles and I am now using 40mm turnbuckles. The swash driver is below the top of the doghouse. Take care.

nice, that head sure does look the part. Autos are definitely a necessary skill to learn, if autos and nose in are all you ever learn with a heli, then you are doing very well.

Don, it's looking great! You can't even tell it was wrecked. The head height looks correct now.

Doc: Nice autos mano

Thanks Emile:

Those autos are what I am striving to do. I think I need to do some tinkering with the ESC settings so that I don't have quite as long a spool-up time. Man, it almost worth the drive down to your neck of the woods for a weekend of flying and warmth.

Barry:

Thanks for the comps. I really don't have room for a fourth helicopter. Lily knows that another two bodies are on the way but the old Jet Ranger body is going to be sent to a fellow in Boston as it is going to be a straight paint job to convert it to a Canadian military training helicopter, not an OH-58A like I had first planned. The repair results surprised me even more than anyone but the shame of it was that the missile launcher was totally wrecked and they are not available as a spare, yet. Oh well, at least it's looking ok enough to fly for a while. Take care.

Thanks Paul. It's too bad that the timing was off when I went through Little Rock earlier this fall. Maybe at Dalton?

Doc, now you've done it. You've given me another way to get at the mounting point for the weapons pod but I am not sure I want to go that far, yet.
