Here are a few more pictures of the horns, horn opening and the work that was done on the Flaps. I added an extension onto the flap horns, so that they would be glued to the top of the flap surface, as well as the bottom, and to the side of the wood block.

The next round of building took place today. Got the afterburner control system and battery installed today. There is not much room in this jet for anything, so every useable space is going to have to be used to get all the parts installed. This area behind the twin 16 oz dubro tanks is perfect for the afterburner system. I have a metal extension on the on/off switch for easy access to it, when the hatch is off. Also, the charge location for the 1600 4.8 volt NIMH will be in this area. The battery is very small, and that is good. That will keep all these components close together.

Also, installed the flap linkages today. I didn't use the metric hardware, replace it with 4x40 and it seems to work great. The 4x40 actually matches the threads in the metal SWB arms used for the flap 8611 servo. Hopefully, I will have a good day to build tomorrow, and show some more progress. Enjoy the pictures.

Well, back to building. For some reason I can never build for multiple days in a row, but hoping to do that this weekend. Off to a good start with being able to work on it Friday afternoon. First up, the filling of the hatch gap in the drogue chute cone area. Started by placing in a thin strip of G-10 board from DreamworksRC behind each of the gaps. Then followed that by masking off all the painted areas with green low tack painters tape. However, that even managed to peal up a small bit of paint around the edges. Oh well, I have to touch it up anyway.
Next, step was to fill with epoxy type filler from SIG, and remove hatch before it got glued to it. Pictures to follow:

Next, up I applied 3 coats of BVM Heat Shield to the area of the fuselage where the turbine and the tailpipe meet each other. Just added protection to the fuselage. Also, I got the 2 8711s installed for the tailerons. They fit without a single bit of sanding to the Servo mount in the rear. Also, I got the SWB arms installed on the servos and attached the linkage to it since this would be impossible once the servo is installed. I had to drill a couple of servo wire holes through the formers, to keep the wires away form the hot turbines.

Next up, was trimming the top hatch opening to fit the 66 ounce center tank. Without trimming there was no way to get this to fit! Nothing a large cut off wheel and Dremel couldn't handle, and a Shop Vac to suck up the fiberglass dust.

Well, as every pilot who builds knows, you cannot build everyday so here I am with my Bandit last weekend getting in some SU-27 practice flights on a high speed BVM Bandit ARF. The Bandit flies great off grass, with the main Pro-Link landing struts. Mine is powered with a Jetcat P-70, or which I will have 2 in the SU-27! It was clocked at 166 by a member of the field who just happened to bring a radar gun out with him last weekend. Anyway, I better get back to building...

It was a good day, I just keep working so here is what I ended up completing for the remainder of the day. I made mounts for and installed the 2 JetCat Christmas Trees. I originally bought the TamJets mount for these however after building them, they place the Christmas Trees at like a 30 degree angle, and with the center tank installed there was no room to have it angled. So, out went the TamJets mount, and I went back to a custom installation, where they are straight vertical, just enough clearance in the back to clear the bumps for the circuit board, and the tiny chip on the back.

Now, came the fun part, the placement of the 2 BVM UAT's. There is barely any room in this jet. Did I mention that before, well it is still true today. However, after having built the Bandit ARF and using the BVM UAT mount in that aircraft, I decided I could use it in this aircraft as well. Placing a call to Patty of BVM, I was headed to BVM for a local pick up. It is great only living about 20 minutes from that World Class model aircraft manufacture. I came home and built the 2 UAT mounts, and started fitting it all over the aircraft. Finally, finding a great place for them, and also allowing the Jet Cat fuel pumps to be mounted directly underneath them. I had to make a back mounting plate which was glued to the rear of the UAT mount. Pictures are better and describing then words. After completing those units, they were installed. The pumps are mounted with the Tamjets Pump mount, and they work Great!

It is nice to see that so many quality pilots are checking up on my building progress! That puts the pressure on even more. The garage today is freezing and I can't feel my fingers after 10 minutes, how am I supposed to build with these weather conditions. I need some 60+ degree days to get the steam rolling. I am taking the L-39 to Florida Jets to wring it out, but before Florida Jets the L-39 is headed to SAM tomorrow.

I think I need to go to Home Depot and get a heater for the garage, so I can keep building this evening. Anyway, more pics to come sooner or later... Remember, if your in it, you can WIN it! I am in it, so I can WIN it.

My plan is to have it 100% complete by March 31st! That way I have all of April to fly it, and get any minor bugs worked out. If I don't make that, then the L-39 will be the aircraft for Top Gun 2010.

Well, got a little bit more done on the jet tonight. I installed the cockpit for the 1st time, and the pilot. Had to trim the pilot even more than I had before to get his head to fit when the canopy is closed. It is a tight fit with the cockpit, with only about a 1/4 of inch underneath of the cockpit tub open before meeting the nose gear door bay. The back of the canopy had to be cut off to get the cockpit to fit with the canopy raised but not removing it from the jet. I undid the screws to remove it, but it appears to have been glued also. I will have to make a hinge system to hold the back covering portion on, which underneath of it can install some electronic gear.

Also, managed to design a ply wood mount to hold to air fills, and air gauges. Will show you were I am going to install them a little bit later...

Beautiful build so far.  Hoping to someday get into Turbines.

Can't wait to see it at TG 2010.

Keep up the nice work.

Well, time to update this site. Wow, it sure is taking a long time to build this jet. This set of pictures shows adding the Heat Shielding to the rear of both turbine bays. Also, in two of pictures created a nice little level location to install a Gyro for the Rudders.

Next, picture includes a couple of fills, and gauges for the retracts, and brakes, and also a jack for the speed brake to plug into when attached to this aircraft, from the speed brake hatch. The last picture shows the BVM Heat Shield blanket protecting the very rear, the red lead is where the afterburner light plugs in to, which look sweet when lit.

Hi Chris,

The UAT mounts didn't come with the plane. I got the UAT mounts as seen in some of the pictures from BVM, ask for the BVM UAT Plywood mount used in the Bandit ARF. It works great.

Here is a mounting system I designed and built to hold the ECU and two solenoids for each turbine. There is just enough clearance when the ducted work is placed over the top. These only added 1 ounce to the entire weight of the plane, and firmly secure these components.

The next step was to replace all the airlines, which were only attached to the retracts with good quatlity BVM airlines. The cylinders had stubs of airline attached, which I cannot figure out why they had that other than for testing at the factory, but then were cut short and of no use. This also was a pain in the butt because some of these areas are hard to reach to cut off, and insert the new tubing. Oh well. Also, removed the gear to give them a good once over. They worked great when tested, hope they work great in flight!

Next up, was to clean up and install the tail boom where the drogue chute from Details 4 Scale will be deployed. As mentioned most of the work was custom designed and created, I only used the chute cylinder, ejection system, and chute itself for the Details 4 Scale kit made for the AD SU-27 which is larger than the Feibo, and most of those parts are to big. However, the chute is marvelous!

I am watching this wiith interest. I thought if you havent done so you should remove all screws in the retracts and oleos and refit with low strength Loctite. I had not made many flights on mine before I noticed screws working loose and dropping out. I too removed all the tubing supplied as it was very stiff.

Hi John,

That is a good idea to use some blue loctite on the retract screws, I am going to do that this weekend. That is a step that actually shouldn't take to long. I still have a lot to do in a short amount of time, thanks everyone for your comments, that keeps me motivated. Should be another busy weekend as I continue to make good progress.

Well, Top Gun with my L-39 was a flop as I tore it up a bit before the show even began, so it is now back to the building board on the SU-27 and get this big awesome jet done, and flying, so starting tomorrow morning I will be back at it. Hopefully, can wrap it up in a couple of weeks, so I have a year of test flying, going to shows, and having fun with this new bird before it's debut at Top Gun 2011.

More pictures to follow on Friday night, or progress made tomorrow...
