Well, I didn't find anything wrong with my connections, I also found my voltage regulator does work. When I had first installed it in the 4* after pulling it from the wrecked Dewey I thought it was not working. I reinstalled it yesterday, checked all the connections, and started up the motor. I ran it for 5 minutes at all throttle settings, without the wing on, picked up the fuse and held it at various angles, except for straight down, that would kill it for sure. Not once did the ignition burp.
Hopefully problem resolved as a loose connection. Still thinking it was the switch itself, it was pressed against the tank and may not have been fully connected.
Here's hoping no more issues and I can actually run a tank through it while in the air and not on the ground. Seems like every time I get in the air, something goes amiss and I have to land. A couple weeks ago, a wheel pant came off, last week the ignition kept cutting out. Darn it only have 4 flights on the plane!
