Looks like you are almost done with the KC furbishment, I will be adding a 40 oz Dubro tank for smoke inside the fuse cone and a 20 oz tank in-between the main tanks.

Will it be too much to ask you to post the control travel you are using on your KC.

TKS.

This is what I will be using. It's what I used on mine and those settings have worked out great, the only change I made was my flaps go down to 40 degrees for landing to give me a little extra drag.

Carlos,
Mine was less of a refurbishment, more of a good going through and setup. Now what you had to do was a refurb job.

ALL DONE. Finally finished tonight and got the chance to run the turbine. Now all that is left is to wait until we get some rain (we are under a drought condition) and we can do the re-maiden. Here is a short video of the turbine run.

Very nice!
I'll be able to work on the Cat tomorrow all day, I now need a 40 and a 20 oz fuel tanks for the smoke, most likely I will work on the tray, air cylinders and valves, looking at getting it done next weekend.

Was wondering if you had a good online supplier for hobby aircraft plywood. I was buying it by the box full from amazon, but was getting way too many warped pieces out of the box.

All the wood for my Turbinator came from Balsa USA, if I need a package of balsa wood that's where I get it from, when I need aircraft grade ply I then get it from the LHS since I usually don't need that much like with this tray.

The air tanks are back in and nose cone back on, the new tray fits good, the double and single Jetronics valves, air gages, on/off switches and receiver are the only things to be mounted on the tray, the gas and smoke pumps are going to be under the tray.

Carlos you are doing a great job. One little trick I did when I had a KK was to put O rings on the 4 bolts that hold the nose cone on. It makes it a lot easer rather than fighting the bolts. Also 1/2 to 3/4 crow worked the best. I did double up the main flex plates when flying off grass fields. Dan

Thanks Dan, the nose cone is on and not coming off again ( at least not soon ) I will be adding at least 1/2" crow for sure and the flex plates have been doubled already.

The dual retracts Jetronics valve is working just fine.
The single action valve for the brakes is not doing so well, on the picture you can see it's plugged in like the dual but, I'm not getting a red light on it, do you guys thing it's burned? Do I have to replace it with a new one?

Does anyone knows if this dual valve ( this one is old ) can do more than just retract and deploy the landing gear?

So far the tray, the airlines and extentions are done, the fuel cells are ready, I still have to mount the fuel pump and smoke pump.

I'm thinking two more weeks for a driving test, engine run and range check at my flying field then, maiden flight two days later at his flying field

The refurbish continues, I got most of the tray install done, engine is mounted now.

I swapped the glow plug for a kero plug, I suppose I need a Y fitting to split the fuel line into two, one for the fuel in and one for the kero plug, Is that correct? And I suppose it's best to install the Y fuel fitting in front of the engine, correct? I haven't had the opportunity to use a kero plug till now, so I ask

I also build me a tray that will be held by Velcro so it can be removed at any time, it will support the 40oz smoke tank, this tray will go in between the spars sockets, the 40oz tank will end up right on top of the CG point, there will also be a 20oz smoke tank positioned in between the main fuel tanks for a to total of 60oz of smoke oil that can be carried

What do you think your take off weight will be full of fuel and smoke oil?

Doing the numbers I came up with 42 lbs on TO, 26 lbs dry weight, 8.5 lbs of fuel ( main tanks ) and 6.5 lbs of smoke fluid ( 60oz )

On TO it's going to be a pig but, a after 5 min it should perform fine, just like my Boomerang XL.

As of last night the butt of the KC is done, it only needs is a fod screen ( DW here I go again ) next is to mount the fuel and smoke pumps, gas and fuel valves, ECU, CG it after that to find the location of the batts, from there, the fun part begins, programming.

Maiden, two weeks from now, fingers crossed.

Not that it isn't extra insurance but I've never had a FOD screen on a kingcat. The front of the engine is pretty protected. I'm more concerned about gear up landings and scraping the back of the turbine.

Agreed, the engine is slanted down a lot.

I am happy to say that the Re-maiden of the kingcat I went through happened today. Other than a couple of minor user induced errors and one "know-it-all" trying to give some bad advice everything went smooth. I did the first flight after the rebuild and then the owner did the second flight. He is taking it out again tomorrow and is going to try and get another 2 or 3 flights. I was helping him so much that i didn't get a single flight on my own kingcat, but sometimes that's what this hobby is all about. Hope to have some video tomorrow.
