Another onboard starter thread
I have a DLE 20 that is not being used with a prop, but as a generator for a silly hobby project (tinkering you know...).
I searched through this forum and found a few threads about on-board starters but did not want to hijack any of them.
I made the starter with a 2 stage gearbox and the flywheel gear is on a sprag. The motor turns over great, maybe 500 - 1k rpm (I can make it faster if I need to).
The crankshaft of the DLE 20 is directly coupled to a big BL motor for the generator; that BL motor weighs about 500 grams so I think it has plenty of mass.
The problem is that the motor keeps backfiring and trashing my starter gears.
What on earth can I do to prevent this? Anybody with experience in this please help.
I thought maybe getting the motor turning really fast and then switching on the ignition?
Maybe some sort of clutch? I will post a pic and/or a vid of the starter soon. Thx,
