Page 2: Welcome Notes
The J600R is the result of significant R&D and manufacturing development undertaken since 1997. In early 2003, we launched the J600R which is the successor to our original popular J600. The J600R incorporates a PST designed modified diffuser, combustion chamber, and tail cone resulting in higher thrust output.

Page 9: Introduction To Turbine
The turbine outer diameter size is also a contributing factor to the efficiency of the diffuser design. As the outside diameter increases, the airflow though the diffuser is smoother and has lower velocity gradients. Our PST J600R is an excellent example of a balancing act between performance vs. size and design complexity.

1211 or BF2000 type recommended). Chemical fire extinguishers can be used but in this event the engine must be returned to PST Jets for cleaning and inspection. b. Always protect your eyes and ears during startup or when in close proximity to the starting of a turbine.
Page 13 J600R Instruction Manual Safety & Notes (cont) Notes: a. The recommended and default settings programmed into the ECU should not be altered unless absolutely necessary. The engine has been tested and operates to its designed performance specifications under these parameters. We cannot guarantee proper operation of the J600/R if the parameters are altered or different fuel pumps and accessories are used.
Page 14: Fuel System
J600R Instruction Manual Fuel System Fuel Tanks Fuel tank & Filter & Clunk Venting the tank Vent plug for storage Fuel tube connection Main and header tanks Setup configuration 1. Use a sturdy polyurethane plastic bottle(s) or specially made Kevlar tank(s) with a total capacity of at least 1.5 liter (2 liters recommended).
Page 15: Fuel Pump
J600R Instruction Manual Fuel System (cont) 7. Fueling is accomplished through the header tank into the main tank. Make sure that air bubbles are removed from the header tank. Air inside the fuel line will cause a flameout. Do not use flex tube or a clunk inside the header tank. The feed line should be geometrically centered in the header tank.
Page 16: Gas System
J600R Instruction Manual Fuel System (cont) 2. The fuel tank must be free from foreign particles. 3. Use good quality turbo oil such as those in the picture above. 2-stroke oil will cause serious damage to the engine and void your warranty.
Page 17: External Gas Tank
J600R Instruction Manual Gas System (Cont) Make sure that the canister/cartridge stands upright in the airframe to avoid liquid gas entering the engine. During start, excessive flame and engine surge will result if the liquid gas is allowed to enter the engine. (This is known as a hot start) This is not healthy for the combustion chamber or your model.

Page 20: Pst Tems -Turbine Engine Management System
J600R Instruction Manual PST TEMS - Turbine Engine Management System The PST TEMS is a highly sophisticated electronic turbine controller that is simple to operate. It incorporates coding and circuitry designed and written specifically for the J600/R. Your J600/R will perform at optimum levels under the control of the PST TEMS.
Page 21: Features Of Tems
J600R Instruction Manual PST TEMS (Cont) B. Feature of the TEMS The TEMS is designed to monitor various parameters of the J600/R. It has full auto-start capability when coupled with the electric starter and solenoid gas valve provided. The parameters monitored while the turbine is running are: Turbine speed (RPM), Exhaust Gas Temperature (EGT), battery voltage, pump voltage, and radio signal validity.
Page 22 J600R Instruction Manual PST TEMS (Cont) 5. Extreme care must be taken not to reverse the polarity of the battery to the TEMS. Incorrect polarity can destroy the TEMS and will not be covered by the warranty. 6. TEMS is protected by 15-amp slow blow fuse and must only be replaced with the same rated fuse.

J600R Instruction Manual PST TEMS (Cont) E. GDT (Ground Display Terminal) The PST GDT has three control press-in buttons. The UP and DOWN buttons are used to scroll between menu pages and to set programming values. The ENTER button is used for selecting the menu page feature and to store the input values into the TEMS unit.

J600R Instruction Manual PST TEMS (Cont) F. Programming Features Start Enable - Press UP until you see this page displayed. This page is used for initiating the auto start from the GDT. Press UP to start the turbine. Another option for starting the turbine is from the transmitter.
Page 25 J600R Instruction Manual PST TEMS (Cont) - Adjust Glow Driver - Press ENTER from this menu to activate glow plug voltage setting. The default value is set at 180 meaning 1.80V. Use UP or DOWN to adjust the value to the desired level. Different glow plugs with higher resistance will require a higher voltage to sustain the glow plug heat during start.

If on, indicates an error in the TEMS software. The user is warned that the unit should be re-programmed by a PST Jets authorized service center, even if all appears to be working correctly. The TEMS will not allow a start and message "Start Not Ready"...
Page 27: Tems Trouble Shooting
J600R Instruction Manual PST TEMS (Cont) While running: 1 Flashing indicates the turbine is exceeding Min or Max RPM and the TEMS is holding the pump to keep rpm within limits. 2 Flashing indicates the turbine is exceeding Max EGT and the TEMS is holding the pump to keep the EGT within limits.

J600R Instruction Manual PST TEMS (Cont) Additional indications can be observed if there are other faults with the setup. 1. Pump starts running and then shuts down on “Pmp” – Flat battery pack or radiated interference between TEMS and receiver. First check your battery charge level this is the most common problem.

J600R Instruction Manual PST TEMS (Cont) 11. You can now calibrate the J600R for maximum speed (or desired derated speed) and higher idle speed as described in the Calibrating MIN and MAX rpm section. 12. The turbine can be shutdown by moving the throttle stick to minimum and the trim lever to minimum.

J600R Instruction Manual Mounting and Installation 1. Carefully insert the mounting straps under the EGT probe as shown in the pictures. 2. Take care that the EGT probe does not bend out of shape and that the end remains securely inserted into the exhaust nozzle.
Page 31: Before Start
J600R Instruction Manual Before Start Study the TEMS section thoroughly for start and operation of the auto start feature. TEMS parameters were factory set but your transmitter needs to be calibrated. Please review the TEMS section for setup and calibration of your radio.
Page 32: Starting
J600R Instruction Manual Starting Recommendation: We recommend that you start the engine on an outdoor test stand prior to installation into airframe. Notes: If air in the fuel line is not removed completely, auto start attempts may not be successful.
Page 33: Maintenance
J600R Instruction Manual Maintenance 1. After each run, make sure that the compressor and turbine wheels spin freely and that there is no sign of any physical defects or unusual noises. The turbine assembly will turn and come to a stop with little braking action confirming that the pre-load on the bearings is still good.
