Call me insane but I had to do this. While waiting for the new body to get here, I will have this one to play around with. I am not sure its fate but this may end up on my wall or at an LHS just as a display piece with no mechanics. I am pretty sure that even all the woodwork I did in this interior will not be usable in the new interior. I found that overall, the center console between the seats is too wide (pouring over pictures made that clear to me in the past couple of months) and therefore the entire seat system is not correct. The new rear wall will be closer to the front and the chassis cover will be reduced in overall thickness but it will still be as wide as it is now.

When I initially ordered scale parts for this helicopter, I got the ProHeli TOW Defender instrument panel and missile sight as a set. While waiting for them to arrive, I gave making my own panel a shot as the worst thing that could happen was for it to be bad and then I just use the incoming ProHeli unit. I stripped the instrument panel for the gauges and switch panels and left the hulk in the box. I didn't even realize that it had the peddles and floor inside (never fully went through the box) but now I decided to install the bare panel in the old cockpit just to fill things up a bit. As I get closer to getting the new cockpit built, I will move things back into this one less most of the bits that will stay in the new one. I may even look for some inexpensive figures to put in it as I have leftover clothes from the first one.

Oh gawd, what have I started?????

So a few things have changed along the way but not the weather. Cabin fever is at a high pitch right about now and I am looking for things to do until the new body arrives. I was not too happy with my choice for the pitch turnbuckles and many hours of searching netted me some very inexpensive Hangar 9 1.5"(38mm) x 4-40 titanium turnbuckles. They work exceptionally well with Align ball links and after resetting the swash servo rods, they fit perfectly into the space between the swash and the blade grips. That makes them the fourth set I have had on that helicopter. I also upgraded my AS350 and Jet Ranger with the appropriate lengths from the same manufacturer. Don't be hung up on having metric lengths, there are inch sizes that may cover some instances, like the one for my TD did.

Since that was done, now all I could do was look at the helicopters and fly my micros in the bedroom, sigh. When the TOW Defender crashed in California, a few parts were broken loose and found their way to the ground, never to be seen again. One was a cover with a foot or hand hold hole in it and that was kind of an open wound in the doghouse. Also, the boom inspection light was removed to install in the new body (no lights in this one) and that was a gaping hole to be filled, as well. I made up a simple plywood cover for the boom light and simulated the light by removing a bit of the first layer of ply. The second cover was initially glued into place but the glue broke away when I started to add some screws for some detail. Funny, now those screws are actually holding the cover in place, lol. Please, send some of that warm air up here from the southwest.

Once again, it begins. TOW Defender, Pt. 2.

I have spend most of yesterday afternoon, evening, and most of today just starting this build. I had intended to get my Jet Ranger redo underway so the old body could be shipped to the Boston, MA. area, but it was not to be. The new body for the TD rebuild came in a week and a half ago but I was not really ready for it. I did a little prep but that was about it. I started it yesterday and I thought that I did good for the amount of time spent on the struts this time around. It took longer the first time as my cutter was not as efficient. It is almost time to put on the JB Weld and let that set but I'll have to think about that a bit. Here are a few pictures with some shots showing a partially converted strut beside the finished on in the other body and another showing the strut as it is, before JB Weld, beside the finished one. Maybe by Monday, they will be at the same point they are in the old body and I can start the very slow process of fitting the much wider struts into the new body. I am still noodling the faring at the top as that is really taking up a lot of thought processes. Some time soon, I hope. Take care.

A few more pictures tonight. I have gone as far as I can with the shaping as I need to get access to a full size MD500 so I can take measurements of many different items on the helicopter. There is an "N" version at Pearson Intl. but the only thing I can use is the width of the struts and that is not going to be worth it. A fellow I know is trying to find a D/E/F version within a couple of hours of here so I hope that he is able to come though. Scaling off a picture is pure hell when a tape measure on the real item is not to be argued with. I will start the fitting to the body of these struts in the morning and maybe by lunch (ok, dinner) I might have the body sitting on its new skids. Take care.

Looking good Don! I really like the titanium turnbuckles for the head. Who is the mfr of the end links? They look good and beefy.

Thanks Barry. Those link ends are actually Align 700 size link ends that I have been accumulating after buying many of the complete rod sets for various projects. Now I know I need to get a few more of them just in case. One thing is for sure, those links will hold up better than the set of copper coloured ones I had on earlier. Take care.

Here are some pictures of the struts in place. I measured the squat of the gear at 40 degrees when on the ground and 50 degrees when in the air. I split the difference this time as my original was at 50 which still looked a bit tall. You all see the picture from time to time of the Vario MD500C at the top of this page (the green and white "V" tail) and those gear make that helicopter look like it is on stilts and about to topple over. They should be much wider in stance. Take care.

I spent some time today laying out the new door lines and found that I can rework both canopy windscreens to a much more scale configuration. I can't do anything about the nose but these changes will make a big impact on its overall appearance. The main wall will move forward and the floor will move up. The rear door will get narrower at the top, move up, and move forward. The front door will be narrower, move up, and forward. I began finding out the position of the rear former of the factory floor as it will be the forward edge of the new TOW launcher supports. I also got some measurements that had a huge affect on the placement of the most important line of the changeover. That was the rear door leading edge. With that I was able to place all these lines so that it is possible and will not into a nightmare. Even though the rear door hinges are not to scale in shape, they are exactly where they should be. All that needs to be done is to fill in the old lines and make up a new sheet plastic rear door and cut the front door out. This had better work, lol.

I finally got out to the field today and did a bit of testing of the head, blades, and one of those E-Flite 720 HD video cameras. I ran the head at 1400rpm which is about 150rpm less than I flew it at last year. It was just a bit too cold for me to try out an autorotation landing but I did do a really nice spot landing caught by the camera. I literally landed in the same ruts I made on the previous landing in one single straight in landing. And they're talking about 4 to 6" of snow tomorrow, YUCK. Take care.

The back doors will not be cut out but a new door put over the fuselage as that is how the full size is setup. The front will be cut to the inner line as the outer one is the edge outline of the door. The outline on the body is not correct for a Hughes 369D (MD500 D model) but is from the MD500 "E". Someone took the shortcut when they did the mould. There is more work in making the door outlines correct, filling in the old lines, and getting them where they should be than there is making the cut-out and new door panel. Oh well.

Got it, I was considering cutting the doors out of my 407. I don't really want to mess that up.

Every so often, Lady Luck taps you on the shoulder and tells you that you've had enough bad luck and it's time for some good. That was me yesterday. I had the TD up in the air and for some reason, I brought it in over the asphalt runway at the club and thought, why not practise some landings with the helicopter at some distance from me. I had planned to do some autorotation practise on the very next flight. So far, I got four flights out if it this spring and everything was perfect.

So, as I am hovering about a foot off the runway and am bringing the helicopter to a sideways profile to land, I heard this gawd awful screech from the motor/gear train and since it was so low, the landing was almost instant for me. Once on the ground, I hit all the right switches and the motor shut down and the blades spooled down nicely. What bothered me was that when I picked it up, the rotor would turn on the one-way bearing but would not turn back against the motor. Oh oh. When I got it to the bench at the club, I got part of the answer. One of the bearings had parted company and that really bugged me as I had just replaced them. Once I got home, the real answer became clear.

The cirlip that we all swear at when installing or removing had decided to remove itself from the slot and that let the bearing drop out of the housing. The remarkable thing about this failure was that the main gear sustained no damage whatsoever. I am now on my way for a ride in an AW109 Grand and if I am lucky, I might get to have a bit of stick-time. When I get home, I will order a motor right from Scorpion with a 5mm shaft (Logo Mod 1. 10t pinion size) and get that on its way from Hong Kong. The only thing I hope is that they only charge me for the motor and not for the shaft, as I already have that, lol. Take care.

Glad to hear that you saved it Don. When you R&R those motor bearings it's important to only use enough "spread" of the circlip to just get it off the shaft and to use the correct pliers for the job. If you open it too far it gets deformed and won't sit properly in the circlip groove on the shaft. As a rule, it's easier to just replace them when you change the motor bearings.

The worst part about this is that I did use the right pliers and carefully replaced it on the shaft. It will most likely be a couple of weeks to get another motor, even direct from Scorpion. I am fairly careful with these as I know that what happened can, so finding it in the condition it was showed me that it was not in the grove at all, but part in and part out. Had it happened on the flight before, there certainly would have been either a hard landing or worse, a fire, as two windings were charred and there was the ominous smell of burnt electronics. It's just money, sigh. Thanks Barry. Your 300 is looking great. Take care.

Thanks Don. Believe me we've all had our hard knocks... At least it wasn't crashed, so all you have to do is throw some cash at it

Well, the motor arrived 48 hours after ordering it from Scorpion. That's 48 hours from Wednesday at 11am when I placed the order to getting it in my mitts at 11am Friday. That is the fastest I have ever received an order from anyone, anywhere. WoW. It went in without any issues and I had already ground the flat and shortened the shaft by the time it got out of its sealing back. No point in wasting another bag for that.

I got out one lousy day to fly and even then, it was still too cold to attempt anything but my regular flying. I did, however, put one of those little cameras from E-Flite on it and this time, I recorded three flights from three different spots and then edited them as one. The next time I go out, I will have two cameras onboard and I will get someone to shoot the ground video so you can see what is going on during the flight. I will see if I can get a picture in picture editing feature as I have not even begun to tap the editing software.

So now onto the latest shenanigans. I was told (and rightly so) that there would be no way I would leave the old Defender body as it is and sure as shootin', I followed form and have really lost it. Way back when (a year and a half ago) I bought two M134 gatling guns with the intention of switching out armament from time to time. The TOW Defender didn't use them but this is sort of not to any actual helicopter but generally like a Little Bird. I am not worried about being scale as that is what the new body is for. I have now tried out the PVC sheet that I got a couple of weeks ago and it is the dog's dangles to use. Easy to cut, form, and glue with CA. I made up a fictitious mount that would let it work with the weapons mount of the TOW Defender. I still have one part left to make up as that is out in the grass at the club in Davis, CA. I might go treasure hunting as there are lots of little bits left there but one pass of the lawn mower might just eradicate everything. Hope this gets a few grins, lol. Take care.
