If it can be small, we make it small

New pcb is 3,5 x 6 cm = 1 1/2" x 2 1/2" (?), for RC-models small is better.
I'm using a small ferritring, outside 18 mm, inside 10 mm, high 7 mm (same wdg's as original)
The high Voltage is about 150 / 150 Volt.....a littlebit low for the ignition coil I use.
The x-tal is replaced by a resonator 4MHz, this include the capacitors.
Strobe isn't on the pcb anymore, I don't use it.
