RE: Cheetah problems on starting
jphn491 1. I am just down the road in Sarasota County 2. START BAD can only be one of 4 things: a. no RPM reading b. no TEMP reading c. RPM not reaching 3000 during start sequence d. ECU battery too low in V - recharge 3. Fuel Pump does not "simply" kick in. During the start sequence, the pump runs very slow which is almost impossible to detect as it sends fuel to the burner inside the combustion chamber. At SwitchOver, the fuel pump begins a more aggressive feeding of fuel then at fuel ramp, again, more aggressive. It simply does not run fast as it does in "Test fuel pump / caution prime" mode. Please check all connectors for correct continuity and verify you have temp, rpm readings when you initiate the start sequence Regards, Eric Clapp Managing Director

RE: Spacing b\w nozzle and tailpipe.
macmuz: Please refer to and adhere to the chart as supplied by Jet Central. The correct distance from the end of the nozzle of the turbine to the edge of the knurled front part of the pipe is 1 1/2 " for the Rhino. This is the maximum setting which produces the most thrust / cooling for the pipe. Also refer to the chart or previous received pdf file for the correct pipe ID to be used. Extensive testing has been done to chart these numbers. OH, pipe is required to be centered to the turbine nozzle as well. Any questions, please email to : jetartessales@aol.com Regards, Eric

Mike: as we discussed on the phone, there is NO system specific manual for the Turbo Prop. What is offered and included with every Turbo Prop sold, is the manual for operating the core turbine. . .Our Super Bee II kero start. We have never produced a manual for the hot section or gear box of the TP. Reason being, it is not a field service component.

RE: Rabbit problems
essyou35: if you still have doubts about the performance of our system, and truly believe there to be an issue with one or more components included with your turbine, please pack up EVERYTHING in the black supplied case and ship to my office here in Florida. I will bench test your complete system (I use JR) with my Rx and Tx and the supplied battery for your ECU. My Rx battery will be a 6v 5 cell niMh pack I use for bench testing. Any issue found (or not found) will be reported on this forum. If you prefer an alternate (non company) source to send to for testing, I can arrange this as well. Please advise as to your intentions.

RE: Rabbit problems
essyou: Again, it is normal for the RPM to jump around when you turn the switch (airborne) to the on position. Again, when you initiate "START" the RPM settle down and read accurately. Should you decide to NOT use the supplied JR style connector from the throttle channel in the Rx to the Throttle channel in the ECU, you are on your own. The ECU derives its power from the ECU battery with secondary power from the Rx throttle channel to the ECU throttle channel port. We strongly advise these connections not be changed. With this connection changed, the ECU may read "Rx power fail" or Rx Signal lost. Last, without this connection, you will not be able to train the Tx to the ECU. Regards, Eric

RE: Rabbit problems
essyou35: It is very important not to second guess engineering of our system. ECU power for turbine operation comes from the supplied battery which you now say you have installed. Please check in the START menu parameters you have the correct battery selected. The secondary power for the ECU comes through the THROTTLE channel on the RX. DO NOT use any other source or channel for this. Connect the throttle channel to the ECU throttle port with the connector supplied. . .or an extension while making sure the polarity remains constant. This works perfectly UNLESS you have a radio issue. . .it is not our system Once set up properly, I strongly suggest you retrain Tx and ECU exactly as shown via the manual. DO NOT do this any other way. When complete, then menu up one scree to verify pulse/% are within acceptable limits. This training must be done PRIOR to any throttle curves being set in the Tx. After running (because the ECU has had much to compensate for) run the turbine at full throttle until RPM reaches preset max and PW is STABLE. Then reduce slowly (at 5 second intervals) the throttle until you reach idle. This allows the ECU to again learn the operation of the turbine. Regards, Eric PS: We simply do not have "noise" issues or static issues with our system when installed in accordance with the manual.

RE: Rabbit problems
essyou35: First, UNDO the secondary battery and install the system as shown on the diagrams within the manual. Replace the throttle cable you modified with a complete new cable. It is totally normal to see erratic RPM readings displayed on the HDT after turning on the airborne system. As soon as start is initiated and starter engages, you will note RPM is actual and not erratic. The turbine system you received has been well tested as designed. If you make changes to any installation or component, you are on your own. . . Second, re train the transmitter and ECU. . .Do exactly what the commands are, then enter by using the + . Make sure the supplied battery for the ECU is fully charged. Make sure the battery type ( within the START parameters) is set correctly When the above are complete. . .and the system is set up exactly as shown in the diagram, initiate a start sequence. Should any issues arise, note them and let us know. Regards, Eric

RE: Jets Over Kentucky Week 2012 /
Lewis: There is a Marathon just outside town on the way in. If you fill up there (assumption 100 gal tank) and only run your generator from late afternoon until retiring for the evening (not recommended to operate it all night while sleeping) you will have more than enough fuel to get you through until Sunday. If you run it non stop from Monday thru Sunday, that calculates to 168 hours. Gen sets require service each 150 hours. Diesel gen sets typically use .8 gallons per hour. 24/7 for 7 days is just short of 135 gallons. Yes, you will need fuel. The fuel systems on gen sets are set up to STOP extracting fuel from the main tank when the level reaches 1/4. I do not have figures for gas gen sets. Hope this helps ! Regards, Eric

RE: Rabbit 100 battery
essyou35: Your question is a good one. In our manual, there is reference to setting up the battery. Your ECU should be the new V10 with black plastic case. If so, you may select the battery choice within the START menu. Battery options are 7.4v LiIon/LiPo/Limag or 9.9v LiFe or A123 type batteries. Please reference your manual for the correct procedure to change battery type used. 2s LiPo is only capable of putting out 7.4 volts so your concern of a hot start is unnecessary. Hot starts are a result of excess fuel in the combustion chamber due to over priming or repeat failed starts due to improper set up. If you think you have excess fuel in the turibine, stand the turbine with starter motor facing DOWN to drain. Selecting a 2s or 2s2p LiPo is perfectly acceptable. We suggest at least 3000mAh with a minimum of 25C rating for optimum performance. Please for verification, email me ( jetartessales@aol.com) your Rabbit 100 serial number for verification of supplied ECU . Thank you, Eric

RE: Turbine oil - where to find.
Hello Ed ! I will have three cases of BP2380 at Jets over Kentucky. It is first come . . .first serve OR you may pre order (with payment) and pick up in Kentucky. I will also have three cases (12 per case) of Amsoil Dominator which is the preferred and well liked synthetic oil recommended and approved by Jet Central for all its turbine products. BP-2380 - $11.00 per quart or $240 per case Amsoil - $12.00 per quart or $ 128.00 per case Ratio for all Jet Central turbines is 2.5% or 1/2 quart to 5 gallons for the ABOVE referenced products. Turbo Prop requires 5% or one quart to 5 gallons. Thanks for reading, Eric

RE: BD-5J Project
Hello Ron: Our Jet Central Rabbit 100 develops 22.5 lb thrust at 6000 feet. This is real thrust. The turbine weighs 2lb 3 oz. all up and averages 7 oz per minute. It is full auto kero start. The start takes about 40 seconds on the average. This Rabbit 100 is delivered in ks start mode however, gas start is also programmed in the FADEC. Simple change over for those who wish to use gas as their choice for starting. Side by side, the Rabbit is smaller than its competitors, generates more "real thrust" and is as user friendly as one could want. Reducing thrust takes less than a minute. A thrust / RPM chart is included in every manual. A thrust reduction to a suitable wide open throttle thrust for the BD-5 does not in any way affect any other operational parameter. We will be offering a Show Special at Jets over Kentucky. . .you may purchase even if not in attendance. Thanks for the question. . . Regards, Eric Clapp Managing Director

They both point out very good observations which if corrected will eliminate most if not all possibilities of air leaks. Each of us are modelers which to an extent, creates the engineering mind within us, necessary to figure out each installation so while complex, works well and without issue.

RE: Rhino problems!! WHERE ARE YOU ERIC!!!
Venicius: Your install from what I can see in the pictures is very good. However, in two of the pictures with the T fitting, there is a clear picture of air in the lines immediately before/after. That air bubble will shut the turbine down. Another question: The flame out with smoke happens when? Is it about the same time during the flight ? If so, this tells us when the fuel reaches a certain level, air enters the system. I would check (yes, I know you have) this as well. We have a customer with an Ultra Bandit who flamed out after 4 minutes in the flight. The cause was the pick up tubing inside one tank had come off resulting in immediate air and shut down as the fuel stopped flowing. Last, are your tanks in series or parallel ? Please know we will do what ever it takes to resolve this. If you suspect the fuel solenoid for example, bypass it to test. I strongly suggest you do not bypass this permanently. . .just for the test. Sincerely, Eric

RE: Rhino problems!! WHERE ARE YOU ERIC!!!
Diego. . . I am right here. . .waiting on your email response to the questions I needed to have answered. Also, Michel in Brazil is authorized to service Jet Central turbines. Flame out without smoke is a result of the ECU commanding the turbine to shut down. Flame out with smoke is surely an air bubble as a result of something in the fuel system. With the "flame out" error code, did you note the temperature ? Does the flame out happen at a specific time point during the flight? The thermo couple or perhaps the fuel solenoid could be intermittent. . . Please advise what you would like to do. I am in the office today and every day unless otherwise advised. Best regards, Eric

RE: Fly Eagle A-7 Corsair Build
DelGatoGrande' Your observation is noted. . .however, tests with our Rhino prove the best cooling of pipe, air frame and the added thrust are realized when the end of the nozzles is between 1.25 and 1.50 inches spacing from entrance to the pipe. This is most definitely been tested and works. The reason is, the pressure area at the entrance to the pipe is enhanced when set up this way. Many of our customers who previously complained of "hot" fuselage after flight, could not believe the difference when set up this way. We include within our manual, a chart of measurements for each of our turbines. Maximum/minimum ID pipe size is noted as well. Readers. . .please check with your specific turbine manufacturer as to their acceptable turbine/pipe set up measurements. Thank you, Eric Clapp
