The engine runs very smoothly. The #8 magnet is to tell the ignition computer to start the firing sequence again at #1.
When I talked to Adrian, that's what he told me.
Magnets for # 1-2-3-4-5-6-7 are "north" magnets, the #8 is a "south "( or vise-versa) When you set up the timing using the provided RCXL timing kit, you turn the magnet ring c/c wise the magnets for all 7 cyls turn on a green light, the #8 magnet turns on a red light.The computer now knows it has fired all cyls. Now time to start all over again.
Yes, there is a wasted spark.
Adrian set up the ignition to run on a 3 cell lipo...7.4-12.0v. I tried with a 2 cell 6.6 life, ran great, and Adrian says that will work very well. He also initially recommended 20:1 mix, but told me that produces a lot of exhaust mess, so he said go to 32:1.
Cheers,
Dave.
All I can say it works very well, and I am very happy with it.
