Now, I did manage to install the ECU's and solenoids on my custom mounts. Here are a few pics. These are hidden in a nice area, and take up very space, and are very secure onboard.

Well, I also had a side project going on while building the SU-27. I had to make room for all these jets in my garage, giving me more building space. So here are some pictures of my new airplane rack. It has opening shelves where the wings can be stored for each jet or other jet items. Thanks Dad for all your help on this project! Great Job.

Almost up to date as to where everything stands. Except, after an early exit at Top Gun 2010, I had some time to work on the opening canopy system. Still more work to do in this area but I think I am off to a great start.

Hi Jason,

i have had my SU27 for some time . I guess it takes a lot of figuring out where to put stuff, as you know there is not much room. I am putting in two 12kg turbines. I figure you can never have enough power. Overall weight penalty is only 500 grams at rear which was only about 150 grams at the nose. One thing to be aware of, there was some problems with the retracts going up. Unless you hit the switch as soon as you rotated it was a bit hit and miss. I did some tests and found that to exhaust all three retract units out of the one valve was pushing it. I have a valve for the mains and a seperate valve for the nose.This setup give almost twice as much authority. I will post some photo's of my install. I have located turbine gear same place as yours, seemed logical. Fuel tanks i have done different. I am using the same two tanks as you but i am using the front tank as a reservoir to feed the middle tank (running 6mm line and clunk) also 6mm vent. Middle tank has 2 x 4mm pick ups that run to two header tanks. I am only using the two main tanks, so i guess i will see how the fuel goes, if i need more fuel i will install two more same as you. I will post some picks in the next few days. I am using a Futaba 14mz and running 2.4Ghz. I have located my receiver underneath the back shelf of the Cockpit on top of the wheel well cover and have taken my antenna's out either side of the canopy area just behing the airspeed pick ups. My model seems to have a lot of carbon fibre so i feel more comfortable exiting the antenna's outside the fuzz.

Probably fly mine next week or so depending on weather, it is now winter here in Australia.

HI John

I have balanced mine at 8.5" back from leading edge at the wing root. I have all batteries , 2x ecu (6cell NiMh) 2x Reciever packs (duralite) and 8 oz of lead in the nose as far forward as possible. I think the two that are flying at the moment are balanced between 8.5" and 8" back so thgat would appear to be a good starting point. my calculations show the ral c/g to be around 8.75" back so i guess anywhere between these would be safe.

Mine is ready to go so i hope to post a video soon.

Alright, starting tomorrow I am back on the SU-27 build, so look for updates tomorrow night with some new progress, after a long delay. Also, wanted to let all know I am changing out the JetCats P-70's for a pair of KingTech USA K-80s, the added thrust should be a nice addition to this aircraft when flying. Stay tuned, going to get the jet finished and flown before the end of the year.

I custom made a mount to attach the canopy UP3 sequencer and servo to the floor of the SU-27 underneath the Power Box tray. Also, notice the sides of the mount. This enables easy lineup when placing in the nose, so the screw holes attaching it to mount all line up with ease. Also, aeropoxied to the floor of the fuselage.

The canopy system sitting on its new mount in the front fuselage of the SU-27. Perfect fit.

Close ups of KingTech K-80E's! They are sweet looking, and very impressive. The FOD screen is a great fit, and very light in weight. I cannot wait to get these babies installed.

The landing gear look really solid and strong. Yes, I plan to fly it at Florida Jets. I am wrapping up the aircraft as we speak. I haven't updated my photo build log in quite sometime but will get to that very soon. Stay tuned...

This plane is really suited to the Merlin 90/Rabbit/Kingtech 80. Mine flew fine on 2 P60 engines fitted out as light as I could. The plane is really not suitable for 2 160 sx.

Hi John, thanks for your answer.

I am now in Armenia, and i fly on up sea level 1350 meters, with 40-42C temperature in summer, so i lost more trust.
This plane can't fly with 2 p60 here. It's the same, flight in UK wit 1 p60.

I like have in this plane thrust/weight ratio 1.1-1.3

Even if the engine ducts are large enough for the engines you will have problems with the fuel. There are 3 conformal tanks and there is no possibility of squeezing in any more fuel. The tanks have 5.3 litres and they are not arranged so they supply equal amounts to each engine. This is fine with a P60 but with a 160 sx would not last you long. You would have a very heavy airframe flying in high temperatures and high altitude, not a nice combination.
