I get what you guys are talking about use the fuse as a test bench and that's why leaving the tail assembly off. I'm going to build a test bench separate from the plane so I can easily diagnose any issues and not have to deal with have to remove it from the model.

Before running on the bench the fuel pump should have a couple of gallons run through it to break it in.

While running the engine on the bench take some notes like;

What rpm gives you the lowest EGT temp............which is usefull to know for shutting down.

What is the pump voltage drawing at... so if it starts to draw more
voltage later you can head off trouble like .....the filters may be starting to get blocked up.

there are all kinds of stuff to be learned on the bench....
The JJ's are coming with fadac ecus now, which are great ecus...great manuals also...lots of good reading to do.

Have fun....these are exciting times for you!

Would you happen to have the instruction manual for the JJ1400. I cant seem to find mine. If so......could I get a copy

In the model I built I did not reinforce the wings as I was using a smaller engine. With your larger engine and it is rather large for the falcon I would run some thin epoxy in any areas you can in the wing especially around the retract blocks and mounts

Yes you must use the booms people ar talking about testing the engine in the plane with the booms and wings off

Regarding the propane I would not use on board gas as it is a fire hazard. Use the gas outside of the plane for starting. A Simple festo fitting of the dia of your pipework will work fine here

has the manuals to download for the ecus...
did not notice any setting pages....which might be there for the jj1400..someplace

Thanks I will check them out. what battery voltage is needed and can you use a Lipo to power the start sequence and run the fedec?

bigplumbs

Most turbine ECU's work well using a 2 cell lipo of approx 2000 mah. The nominal voltage of such a lipo is 7.4 volts or 8.4 vilts when fully charged. You need to check the manual however as I am not sure about Jet Joes

Dennis thank you for all great info

This next weekend I'm going to mount the engine on a test stand and see about lighting this thing up!!!!
