Default JetCat Newbie - help requested

Dear all

As a newbie to the mini-turbine world, I am looking for some pointers from the more experienced among you. Specifically I am interested in:

1) does anyone have access to an English manual for the new JetCat v12.0 ECU?

2) does anyone have access to a mini GSU manual in English? All the English manuals I can find focus on the handheld GSU with a statement that mini gsu can do all the same things- which I'm sure it can but it has different buttons on it vs the handheld GSU (no Set or Spool buttons)

3) there is reference in many of the jetcat manuals that multiple engines can be connected together in parallel, but I cannot find any information in English on how to do this. Will multiple ECUs be needed or can you run multiple engines from one ECU? Can P220rxi engines be connected in this way?

4) i am looking to set up an engine test bed with a manual throttle control (not rc). Does anyone know what voltage needs to be applied to the throttle connector on the jet cat GSU to activate it?

Thanks loads for any consideration on the above. Taking a step into a big world and any help adapting would be appreciated.

Thanks

Andy

hi Andy,

i don't know about manuals, i would not be surprised if there is not one but i don't know for sure.

with multiple turbines you still need one ECU per turbine. the ecus can communicate with one another on startup, as far as i remember that is the only advantage to linking the ecus in a multiple turbine install.


as for the control of the turbine, it is not voltage controlled directly, the input to the ECU is a servo signal.

if you are not using a typical rc receiver, a pulse width modulated servo signal that can be generated with a servo driver. these are little boxes with a knob that lets you move a servo.

Thanks Mr_Matt, that's all really helpful. Sorry for the delay in sending my thanks, I had to do some reading around to ensure I understood your reply and didn't need anything explaining 😀.
