Still Repairing Stuff...

Well, I picked a good time of year to decide I was gonna check things over and get back active in the local flying club, since it seems I'll be busy repairing stuff for a while... Things have been "parked" over 2 years, and it's amazing how much goes bad from inactivity. While checking over my flight gear, I discovered my glow driver wasn't working. I opened it up, and found the battery had failed and was leaking. No biggie, I've been chopping up a good 16 cell 3000 NiMH RC car pack for batteries to build more receiver packs for my airplanes, so I pulled a sub-C cell from that and slipped it in. Nothing. I opened it up, and saw the center contact was oxidized black. I grabbed the Dremel tool and a small stone, and removed the oxidation to expose the shiny yellow brass contact. Once reassembled, all was well. Another piece of field gear ready to go!

My broken glow driver...
 

A 3000 mah NiMH salvaged from the RC car pack...

I removed the outer jacket so it would slide into the glow driver easily...

The center contact in the upper housing was oxidized black, and wouldn't make contact with the battery...

After repairs, all was well and ready to go flying!

How to select the correct glow plug...

There's loads of info on this topic, and I've consolidated what I thought were the best pieces from James McCarty, Brian Cooper, and Brian Gardner . Rather than repost a pile of stuff I have on my website, I'll point you to it. You can see it on my website at http://www.RCDave.net or you can link directly to the info on one of my servers at http://www.scootworks.com/rdrcdave/gloplugs.html . I hope this helps some of you as much as it has helped me!
