 Well I haven't flown my prop planes for a while and after today I think I got a little rusty LOL. .

So as I got home I had the urge for a scotch, and what a way to enjoy it in the shed admiring my planes.

Anyway to cut the story a little short I couldn't help myself to get my hands a little dirty.

This was the end result.  Haven't done the area around the wing yet but will do.

Levi, He made it for me, supposed to ship today... Tam, if you want to hold onto it a while longer to duplicate it for him, feel free.

Damn

I better re-engineer my JL mig and put a pair of 100's or something in her just to keep up with you boys at Wangaratta 

Just a little up date on my Mig 29. Things have been a little slow but i have been very busy.  I did some enforcement around the leading edge of the wing in the fuse.

I have also installed the rudders which i used the JR DS-3401 in the rudders.

The servos which go into the rudders are small so the standard aluminum servo mounts supplied will not fit. I made my own out of 25mm x 25mm x 3mm aluminum angle.  

The rest was as usual with the gluing of the wood blocks then screwing the aluminum servo mount onto the servos and last of all screwing the mounts onto the blocks. I prefer to use hysol to glue in any blocks on my jets.

I also mounted the strobe light to the right rudder which was supplied by Intairco and manufactured by Detail for Scale.

The only problem i had with this was that one of the rudder formers was in the way and i had to make my own extra long drill bit to drill a small hole in the former for my wire to go through. This must be dome with extreme caution as you have not got much to play with and there is a risk you could crack the rudder. With a little patience things get done with no damage.

Next step was to balance the Elevators.

I do this by sliding the elevator into the plane. I then tape a small sandwich bag to the leading edge and i use lead shot to fill the bag until the rudder is close to level.

I than weigh this up, drill a small hole in the side of the elevator, mix up some 30 min epoxy which i weigh. I than adjust the weight of the lead shot to the epoxy i have mixed poor some epoxy into an injection needle and inject it into the leading edge of the elevator. I than poor the leads shot in with the rest of the epoxy and leave it standing with the leading edge facing down overnight. By using lead shot number 4 i am able to have the weight as far as possible inside the leading edge which reduces the amount of weight needed.

The Elevator servo used was the Hitec HS-7980 which will give you 36kg on 6 volt or 44 kg on 7.4 volt.

The servo housing in the fuselage has to be enlarged a little to fit this large servo in but its not a big deal.

However after trial fitting a few things i found out that the bottom of the elevator horn was going to hit my tail pipe very badly.  This was not good news but could be fixed.

My first thought was to get a set of smaller pipes fitted but due to the size of the engines I did not want to go smaller in diameter so this is what I did.

The inner tube in the fuselage where the elevator slides in i was able to file 5mm of that which would bring the horn 5mm closer to the inside of the fuselage. I than had to mill an extra 5mm on the elevator shaft. The elevator shaft has a groove or a flat spot on the round aluminum shaft for the horn housing to fit onto. Since this was milled an extra 5mm I was than able to cut an extra 5mm of the shaft.

The horn housing is basically a block with a plate underneath which is screwed by four machine screws. I had to file one corner of the block but still needed four screws to hold the plate, so I was able to drill and tap another M3 tread in between the two screws so now I have 2 screws at one end of the plate closer together. This gave me the opportunity,

To file one corner of the block to give me the space I needed. Unfortunately after all this it was still not enough as it was still hitting the pipe a little. Being a dual wall pipe I decided to cut the outer wall of the pipe a little to make room for the horn housing to move without hitting anything. Some mite says that this defeats the whole purpose of a dual wall pipe but I did not have much more of an option. My maintenance is very high with all my jets and I do check thing very often including the tail pipes with my inspection camera so this is one thing i will keep an I on. I also only have a single wall thrust vector pipe on my Rookie which to date still looks like new and has not looked worn.

Once all that was done the next bit of the project was to install the four servos for the thrust vector. These will be Hitec  HS-7955 which put out 24kg on 6 volt.

This once again was a simple process which involved Hysoling some wooden blocks than screwing the supplied aluminum servo mount onto the servos and blocks.

I than moved onto the nozzles but before i install them I wanted to weather them a little. They looked to new for my liking and also they needed some heat protection. I coated the inside of the nozzles with BVM heat shield and once dried I sprayed the inside of them black with  Dubli-color High heat with ceramic paint. This can be bought in a spray can and is usually used to spray engine blocks with.

To weather the outside nozzle I first dabbed on the original painted nozzles some Flat blue. Once dried I dabbed on Blue violet waited till it was dried than dabbed on Gun metal and once this was dried I finally dabbed on Titanium silver. All the dabbing was done with a cloth rag. Only after it was all dry perfectly i than used a mixture of wet and dry 1200 sand paper and a rag with a little thinners to work the nozzle to get the effect i was happy with.

Once this was achieved I mixed up some oil paints in Black, brown, blue, red, and white until i got the color I was happy with and applied it with a rag. This requires a little trial and error as you have to apply it thick in some places and not so thick in other places until you get the effect you are after. Once I was happy with the finished result I left it to dry for a week as oil paint seem to take forever to dry.

The installation of the thrust vector was very straight forward.

The only thing I changed was the carbon fiber tubes which slide onto the pushrods. The once Skymaster supplied i found them to big and where catching on the thrust vector. I also prefer a tighter fit. So for the four rods which where required for the push rods I supplied my own. I also installed aluminum ball links on the servo ends.

Once all this was installed I made up my small board out of carbon fiber look alike.

This was to house my filler valves and gauges for the gear doors and brakes. It will also house the two Jetcat GSU and Jetcat charge jacks.

Next will be the installation of the tail pipes, and engines but until than Happy flying.

I will post some picks for you all to look at.
