Ah thanks for chatting with me!

I'm bored stuck here at home today, unable to fly Grounded in the hangar again!! [:'(]

I'm a test engineer, currently at nvidia, in santa clara, ca. Let's see, got about 26 years electronics lab experience now...

Yep, it may 'look' dangerous, but this system is thoroughly checked out. As long as it does not get stepped on! [:@] I went over the whole thing in the lab, with current meters as well as volt meters.

There is also a cooling fan blowing on the whole mess - that's big tip right there - having a cooling fan blowing on the chargers has several benefits: The chargers run more efficiently. They run cooler, which drastically reduces the chance of "thermal runaway", which is always a precursor to FIRE. Their service life is also increased because lower operating temps increases MTBF (Mean Time Before Failure).

When I get that 'charging board' nailed together, I will put a small 12V cooling fan on each charger - I found these PERFECT fans off of some dead PCs I found in the trash!!

Also, if you look closely, one of the E-Sky chargers has a bunch of cooling holes I drilled in its plastic case. Hmm, think I'll do the other one now...
One word. Ratsnest, lol.
Hey, I was in you're neck of the woods a few weeks ago, playing some cqb airsoft in one of the abandoned chip manufacturing buildings there. That's one heck of a complex you guys have got.

I fixed my ocsilation problem. It was the main blades, out of balance I think. Put some new main blades on and she fly's like a dream. I'm gonna try and balance the old blades and save them for spares.
Save'n for a lipo setup now.
