Over the last two days I have begun fitting the G3i Electronic ignition to the aircraft. Althought it will not be actually activated until after 20 hours of flight testing. I need to warrantee the Mags first.
The system fit in the nice space I assigned for it. I cheated a little and only bolted them in at present, however, if I need to uninstall at any point I will fit platenuts. For now however, it will do the job quite nicely.
There is a need to wire the system into the aircrafts power supply and to establish a good ground. Apart from that, the primary wiring is in place and the units need to be connected with a common 5 wire plug.
After that has been complete and at the 20 hour mark, I will modify the Mags and construct the Auto spark plug harness. This will allow me to use automtive spark plugs on the system.
Sounds very experimental doesn't it??
Well, just remember that the engine size is 8.8ltr 6 cylinder and there are 12 plugs on it. If we halve the engine capacity to a 4.4ltr 6 cylinder, this is a regular, albeit large, car engine. They only use a single plug per cylinder and the nature of spark propagation is the same once ignited. So a very simple but cost effective solution. $70 per plug vs $10. I worked out that this equates to over $14k in savings over the 2000 TBO of the engine with new plugs every 100 hours.
