So you got the airplane and now you want to spend the big bucks on the powerplant? Or maybe you just want to see how they are installed. Turbines need a different installation than Ducted Fan and will require some special equipment. First you will need a Stainless Steel or Titanium Tail pipe for the exhaust. You need to make sure all cable (especially servo and antenna wires) are kept away from any hot spots on the plane and that the temperature while running the engine does not melt your plane. You need to carry more fuel, so you got to have lot's of space to carry it (about 400-600% more fuel). Most important of all is = Can your plane handle the speeds and loads of a Turbine? When you fly turbine your plane is able to fly faster than a ducted fan but it will also be heavier (about 4-6lbs minimum (that includes gas)). Will your wings handle the loads? Well, you built the plane, so only you know.

O.K. People, This is an F-20 and a BVM Fury (Navy version of the F-86). The Tigershark is the same size as a Byron but it was kitted in Italy. We do not know that actual manufacturer. YOU CAN CLICK ON THE PICTURES TO SEE THE LARGER ONE.


First two pictures show the Plane from the back with the engine running. Kinda looks like the flash of the camera, but that is the flame of the Turbine running about 1/3 throttle. The picture on the right show's how the tailpipe (Thrust tube) is installed into the Airframe. Note that there is a GAP between the structure and the actual tailpipe. That is there to keep the plane from overheating and also to help the tail-pipe (thrust tube) cool down from any air that goes in through the landing gear door or any other means besides the intakes.


Picture to the left is the Electronic Control Unit (ECU) for the Turbine this plugs into the throttle channel. This will monitor the Temperature and pressure of the Turbine as well as control the speed (throttle). Consider that part the Brains of the turbine. The yellow stuff below it are Kevlar Fuel Tanks. Highly recomended but not necessary if you are flying Turbines. Picture two, three and four are of the actual Turbine installed in a By-Pass. The black thing surrounding the actual Turbine is the By-pass, it's functions are simple. 1. Take all the air from the intakes and place it around the intake of the Turbine. 2. The Air that does not make it into the engine is then directed to flow around it to cool it down and finally exit and mix with the HOT exhaust coming out of the turbine therefore lowering the tailpipe temperature. 3. Keep other wires, lines and or fuel away from running engine. 4. Try to somewhat protect your engine in the case of a crash. That will depend on how hard you crash (don't expect anything to be alive if you come head in at 200MPH). Picture five is the same as the one before it (picture four) but it is a little larger. Last but not least is a Sophia J-850 and as you can see, there is no By-Pass installed. Again, not required but highly recommended.


O.K. People I am a RAM Rep therefore use RAMS (well duhhh) but I will also post other pictures as I can take them. Above are four pictures of a RAM 750F start box during the actual start. The first shows the RAM Startbox in the ready mode with the numbers of Runs on this engine so far (cycle 15)Picture 2 is the Fuel Ramp. The ECU and start box switch the engine from the propane used for starting to the actual Kerosene Fuel for running it will also whow you the EGT and Compressor pressure. Picture 3 shows the engine in the running mode. It also show the EGT (exhaust gas temperature) and the compressor pressure. Last but not least, the engine in the Shut Down mode also showing the EGT and Compressor preasure.
