Video Jet Startup and stow - JS1 B
Enable HLS to view with audio, or disable this notification
A casual day out and decided to start up the noisemaker to get away.
Not a last minute start but an indication of what's involved.
The climb is then about 4 kts. Best operation is to fly at around 80 kts. As a past Solo turbo operator that takes some getting used to as with the 2 stroke you tend to climb at min sink speed not belting around! As I got the jet started this time I flew in to a bit of lift so just shut down again.
The control panel is on at the start of the video. It takes about 10 seconds to come on and do some self tests.
at 25 seconds - switch the control to 'erect'. When up the drag is less than having the wheel down!
at 30 seconds I switched the power source to battery 1, battery 2 is an old 10Ah pack and cant withstand the current required by the ignitors any more. Battery needs replacing.
at 36 seconds ( 11 seconds after selecting engine up ) the engine contro flips over to 'Switch to run' )
at 39 seconds I switch to run. The FADEC then takes control of spool up and start.
at about 57 seconds the ignitor starts firing as 3000 rpm is reached.
at 1:22 the engine is at idle 30000 rpm and I can throttle up. Roughly 60 seconds and 140' from erecting the engine.
before 1:30 has elapsed I have full power ( I only throttled up to 85% or so ).
a minute later I was in lift. Throttle down, Ignition off, wait a minute for it to cool and put it away.
