8 Multiengine Installation

 

   

For multiengine installation, first set up each turbine as per manual, start and run each engine 
separately. Then, when the Turbines are starting and running smooth, plug the throttle leads 
from  each  of  the 

POWERPACK  /  ECU’s 

into  a  “Y”  connector  and  plug  the  central  lead  into 

your  throttle  channel.   Now  both  turbines  will  start  at  the  same  time  and  shut  down  at  the 
same  time.  This  is  preferred  over  individual  starting  and  is  a  simple  way  of  assuring  you’re 
taking off on both turbines! 

   

Helpful Tips

 

   

·

 

If one turbine starts and the other doesn’t for any reason, just cycle the throttle again; 

the one not running will enter the re-start sequence. 

   

·

 

In  multiengine  installations  always  have  each  turbine  with  its  own  complete  fuel 

system. 

   

·

 

As the POWERPACK / ECU has auto restart feature, if it is required to shut down after 

the  turbines  are  running  and  need  to  restart  quickly,  just  raise  the  trim  to  the  ready 
position  and  cycle  the  throttle,  when  the  auto  cool  down  cycle  gets  the  turbine  to  a 
safe temperature the POWERPACK / ECU will restart the turbines automatically. 

   

·

 

Place  on/off  switches  on  the  throttle  lead  before  the  “Y”  connector  that  plugs  the 

POWERPACK / ECU’s throttle channel into the receiver, this way you can shut off one 
turbine  or  the  other  on  the  ground  or  start  one  at  a  time  by  turning  off  the  engine 
desired,  it  is  also  helpful  if  you  have  a  “BAD  START”  on  one  turbine  to  reset  the 
POWERPACK / ECU.
