| Hi all,
Well, I was looking at the factory charger for the Birdseed Battery. I was trying to decide what to do with it (after almost frying the battery with it when I first used it). I knew I was NEVER going to do that again! See I forgot and walked away for about 3 hours. It was so hot when I checked it, I got scared.
Anyway, at least the ADAPTOR is pretty neat! I noticed the round plug from the wall transformer also is the exact fit for my Hitec Eclipse TX.
Since I also have a Hitec CG 335 charger, I knew I could charge my TX with it and also my BS battery with no adjustments from the Charger. (It automatically figures out number of cells.)
So I cut the plug (with about 3 feet of the cord) off the wall unit and hooked it to my CG 335 charger.
But when I tried to charge the BS battery through the adaptor, it wouldn't !
Then I plugged it into the TX, it began charging fine!?
At this point, I decided to open the adaptor an... bingo, there was a diode in there!
I simply soldered a piece of paperclip across it, thus disableling it and allowing me to charge my BS battery or my TX from just the one line from the charger.
By the way, the CG 335 charger will charge up to 24 batteries with doubling circuits and continues to an accurate peak charge even if the souce battery drops as low as 9 volts. It's pretty cool.
I charge my BS batteries at 700 ma with it It never takes too long, since I never run my batteries completely dead anyway.
They peak at 10.5 volts typically from what the ammeter says on the screen.
Anyway, you old Hummingbird pros already probably know about the diode, but I just thought I'd bring it up in case someone else wants to use the adaptor direct.
And for those interested, I'm still running the Century upgrade motor and same tail motor with Hornet blades. There was no change of gearing at all.
Lower pitch and higher head rpm, seem to keep the motor much cooler and the tail rotor motor hardly needs to even run.
The TR motor has plenty of power at this pitch setting as far as I can see.
Of course the H-bird loves to fly right turns anyway.
When do I start knocking on wood?
Happy flying,
Dave
