The reason I inquired about your engine is since it is new in box that tells me you have the fuel pump, ICS or the (on board control unit) as well as the GSU (ground support unit) this is the device where all starting and operating parameters are set such as fuel pump voltage, glow plug voltage and so on. This also provide many other bits of information such as temperatures, RPM, total engine run time since new and each flight, battery capacity used for each run as well as diagnostics for a failed start.

Now as to is there a first start procedure different from what is in the book. Perhaps a break in procedure? the answer is no, none that I have ever heard of. Follow the startup info in your manual religiously. If new the individual startup parameters should already be set at a safe point but learn how to use that GSU and be sure the book initial parameters are set correctly. This is why I inquired if the engine was used.

Depending on your engine you may or may not (I have no Jetcat engines and they do vary) have to mount also on your board a main fuel solenoid and a propane solenoid. One all important item should be a main fuel manual shut off on your test stand and in an airplane from the UAT outlet to the fuel pump. This is the first action to take is to shut this off should a hot start occur in other words blowing excessive flames out the tailpipe.

Another item you are going to need is a leaf blower. Its funny when one first visits a Jet Rally it looks like some sort of gardners convention. The purpose of this is two fold first is safety, should a hot start occur after the fuel is shut off the blower is used directly into the intake, this first will blow out any remaining internal fire and by keeping the shaft spinning will prevent shock cooling of the blades. The second reason is when normal shut down is selected the ignition stops but the starter motor will keep cycling on and off until the engine gets down to around a hundred degrees. But if one uses the blower on shut down in the intake it will not require so much running of the starter motor and conserve the engine battery supply.

In the Jet forum I linked there is even a JetCat specific forum there for more specific info.
