The scale fuse kit only comes with the parts that aren't in either a Trex or Chaos kit. It has the angled gearbox and short upper boom and torque tube, but not the main boom. I have a heap of spares due to my parts collecting neurosis. I didn't want to waste the Chaos carbon boom as it is hidden inside the fuse, so I just slapped one of my spare Align ones on.

A few more pics of the frame assembly. The roll and pitch servos are at the rear and the elevator servo in front of them. The Chaos 600 control arms etc are all used. The major difference to a normal Chaos/Trex 600 is that all servos are rear of the main shaft and only one link rod from each servo to control arm is used. Due to the positioning of the elevator servo, two links aren't possible and it's not going to be doing 3d...I hope...so two links aren't necessary. It's only a very short link from elev servo to control arm, so a bit of trial and error with servo spacing from the frame was required to get a straight run with no side load on the link. The whole frame is very compact and everything fits snug without wasted space. I fitted the boom supports onto the lower gearbox mount screw to allow it to fit into the tail section. Again very little room, so all the bits have to be trial and error fitted to get them into a suitable position not rubbing or binding on the fuse. The boom supports attach via a supplied boom ring which replaces the Chaos horizontal stab, boom support, mount. This is due to the tail being quite thin at the rear for the scale effect. The boom supports are very close together at the rear, so the support ends needed to be angled at each end so as not to have a bending load on them when fitted. A bit of time in a bench vice and a spacer and longer screw at the tail gearbox mount and they are a perfect fit. I have setup the tail servo...probably overkill for a scale heli..a Futaba BLS251, but it has been such a great servo on my Chaos 700 that I lashed out the cash and bought one for this. I was never really happy with the Align DS650 on my Chaos 600 and may have to get a Futaba for that too. The frame mechanics are pretty well all done now, just to fit the ESC and tidy up all the wiring. I have a CC Ice2 80HV that I am going to use. I would like to attach it to the frame to keep the system as modular as I can to eliminate the need to undo a billion things everytime I put the mechanics in and out of the fuselage. I am probably going to attach it to the right hand side of the frame behind and lower than the main gear. It wont be working very hard on 12S and will have very short wiring to the main batteries from there. I have opened up the doghouse body through the exhaust pipes with a dremel and there seems to be plenty of airflow openings for cooling. Now that the Evil Doctor is pursuing the scale guys to get an entry into the current competition, I am going to fit the mechanicals into the frame and fit the tail section as a trial fit and drill and mount the tail screw attach blocks. Once the tail is all mounted up, it's time for the interior work and then some scale exterior detail....only a month till the competition ends.....

Very Nice bob! Glad the picture uploader is working well! That is the one thing I hated about this forum.... Going to keep making some improvements...
Cant wait to get started on my scale project, Maybe in another month or so!

that was a bit of a problem, allspunup..but hey...forums take a while to mature and this one is coming along in leaps and bounds. Just look at the membership now...it's increasing almost exponentially. I am looking forward to your scale heli.
It's kind of funny in a way, as when I started with RC helis I said I would never go near scale as they would just be an expensive smoking hole in the ground when they crash. But as I seem to be able to reduce the crashing incidents and find that I cant fly as much as I want to, but still want to do heli stuff, they are the logical conclusion. The 3D helis just build too fast. A scale heli always needs something done to it so the build lasts a lot longer.

Bob, Now that is one super job on the mechanics! I am impressed! A scale build such as yours is a little too rich for my blood right now so I have to settle for something more budget minded. Some day maybe... ;D

Thanks, oldcitypainter.....they aren't cheap by the time they are finished and I cant really afford it either. The money should have been spent on our house as it is in dire need of some...well...lots of work. But, the wife hasn't murdered me yet and you only live once...so...helis it is...

I have done some work on the scale cockpit. Once again RC Aerodyne have delivered a really nice piece of kit. It comes in black with the instruments already painted and includes a couple of crew figures. I will use them if they are needed for C of G adjustments. The seats come with a fairly substantial surround..I guess that is an armoured version. The heli that I am modelling mine on has cut down seats and a gray interior, so I got the dremel and a bit of masking tape and a rattle can out and the interior is basically finished. The base interior is fitted first and the seats and main instrument panel are fitted once the base is in the heli. A bit of double sided tape holds them in place. As usual every thing fits perfectly...no trimming needed, other than a tiny bit behind the main instrument panel as it comes setup offset to the right. That is how the panels are on the early Hueys, but the twin hueys have the panels centralised. The first pic is how the cockpit is stock and the second is how it will go into my heli....

I have done a trial install of the cockpit...perfect fit. My typical school boy error though was poor planning. As a total novice with scale, I rushed into the build without enough prior planning. Rule number one: Plan your build. That includes choosing your scale subject and researching any changes you need to make to your model before building. In my case, the subject I chose has a gray interior...the kit came with an olive green interior. No biggie, just a bit of paint, but I should have done that before I fitted the mechanics and some of the windows. It meant a lot more masking and a bit more difficult to paint with stuff in the way. Anyway it all went well. A few pics with the interior in and some small detail additions: fuel filler caps, repainted exhausts (came flat black) to a more metallic look with some soot fading and painted the heat exchangers below the exhaust outlets.

The scale rotor head came in from the "House of Cliff"(RCA) today....it's a very nice piece of kit .....the cherry on the cake....I still have a couple of days of my shift at work yet before I can start heli stuff again....the rotor head is going on as soon as I get off work......only a couple of weeks left for the scale competition....lots to do yet.....it's going to be a struggle... I really would like to get over to the States one day.....a couple of great people to visit...one who does a lot of hard work on this forum.....he is not as Evil as he might pretend to be...and I would love to visit Cliffs cave of heli goodness.....

Wow Bob, looking awesome, if you finish on time, you'll have a winner on your hands...
(I'll park my Huey in its shadow...)

The tail install is next....for the first attempt...a couple of cups of coffee and some tranquilizers might help.. Just kidding...time and patience will do fine. The tail section of the fuse slides over the tail boom after you take off the angled extension boom, tail rotor assembly and torque tube and the linkage rod. The fuselage tail slides in very nicely and is an amazingly good fit. The blurb by the manufacturer says these helis have the molds cnc'd and it shows every time you go to fit a component. The tail unit of the fuse mates to the main fuse real well and the vertical section of the tail is square to the fuse. No need to jiggle it about and grit your teeth while you drill the holes to mount the tail to the fuse...it just sits there perfectly square. Fitting the raised section of the tail boom into the angled gearbox and sliding the tail rotor drive assembly into the raised vertical fin is the part requiring patience. For those who have gotten a liitle testy while trying to fit a normal tail onto a boom and lining up the torque tube at the same time, well , that is nothing compared to this... The angled gearbox has to be prised open to allow the short boom tube in..the locating pin needs to slide into it's slot.....the torque tube needs to be as vertical as possible and you sort of shake and jiggle and then ....you are in.....dance around a bit...you have earned it. Once it is in place you need flexible fingers and angled needle nose pliers to attach the linkage rods and bellcrank. I use a method that I use at work to fit nuts onto screws in unreachable positions....I ca glue the nut to the tip of my finger and reach around behind the screw. It sounds tough and it is, but the second time I fitted the tail assembly it only took about a half an hour as opposed to the two hours, the first time. One thing that I will have to address is: I need to make some sort of pin to lock the tail rotor assembly onto the raised short tail boom. The boom section come drilled, both sides in fact, but you cannot use the stock fitting that you would normally attach your vertical stab onto as the unit will not fit down into the tail of the fuse. I removed the fitting and used two shorter screws to clamp the tail rotor unit onto the tube, but I will not be comfortable until I fit a screw or make a plate to lock the tail drive assembly in place. As I said above, every major part that I fit onto this heli, just fits so well...I may be used to old school things that were made in some ones shed...and only roughly fitted together, but everything on these kits just square up so well.

I fitted the lighting next....I have used the RCA kit. It has the red and green navs, two red beacons and three strobes which are on whenever power is applied to the channel they are on. It has three taxi lights and two landing lights that can be switched on whenever the channel they are on exceeds + or - 85 of the channels travel range. My poor planning comes to the fore again as I don't have any spare channels to switch the lights. As I am using the 3GX, it uses the gear channel as the governor. Although I am not using a governor, the unit will still process that channel and output it through the throttle signal wire. If I had used a full size receiver instead of the satellites on the 3GX, I could have routed that signal for the lights. I may change it down the track if I convert my 600 to FBL and I can swap the receiver from that into the UH-1 and the remotes into the 600. I fitted the landing light anyway so it is there ready to be used. For the other lights, they will come on when I connect my receiver battery up. I have installed a strobe in the tail, red and green navs in the lower side fuse mouldings provided, just behind the door cutout, and a beacon on top of the doghouse. Also a beacon and strobe under the bottom of the fuse along with the landing light. The lighting kit is real neat...easy to install, just make a hole with my Dubro hole reamer, that I used to use on my rc car bodies, and pop the light into the hole and hold it in with some tape. I just run some tape over the wiring to stop it chafing and snagging and it's job done. The lights all work well...they all come as clear globes....and operate in their respective colours. I added a bit of clear color paint to the green and reds and that is it. As a matter of fact, I like this lighting caper so much I am going to get a couple of these kits and put them on any heli I can.....3D or scale. Easy and cheap....some of my most favorite words.... The landing light, beacon and strobe underneath and the green nav just behind the door cutout. The strobe in the moulding in the right side of the tail. A beacon in front of the exhausts. The lights are provided as straight globes, I have not bothered with scale housings...the only one that probably needs one is the upper beacon and that may happen one day.
