The only thing is when you plug it in the light does not come on the usb charger cable like it does on the laptop, Instead a green light comes on the usb hub and then goes out when the charge is done.

Should work good, Mine is only 300mah and takes 40 minutes.

Never seen a plug like that, What country are you from?

From Argentina. 500mA is it excessive? What do you think?

Thanks.

80 minutes!

My rig does it in 50-60minutes with four s107's attached

GO Belkin 4 port Hub!

Give it a try, Maybe the pcb on the battery will limit the current.

Yeah my laptop usb's only put out 100mah so 80 min charge times

But my new powered usb is 300mah and takes 40 minutes, Seems so much faster and the heli has more power now.

Hi Red, thanks for your reply.

Hmmm ... Now let me think . I do not want to ruin the battery with 500mA .

Killbucket, could say about it?

EDIT: Killbucket told me that I can use it and will not damage the cell

Thanks, guys

lower the current, longer the battery lifetime.
do not charge your lipos with current exceeding 1c rating.
be patient and wait 20 extra mins for a good, low current charge.
i charge my s107 with .1A current.

Stupid question, I know:

I just got my 107 in the mail (it's yellow! The color I wanted) and it's on the charger now. Are the rotors supposed to be straight across from each other or just moving around like mine are? I've seen pictures of all four blades pointing back, but I just figured you would tighten them up before you fly. Any help, kinda confused.

TIA

Hey, I'll take a stab at that one.
I'd leave them sloppy like they came from the factory.
If they're too tight, you can get the dreaded "toilet bowl effect", where your heli hovers in a permanent rotation, even though you're not telling it to.
I'm a total n00b, so let's see if the experts agree.

Post Maiden Voyage Report:

NO CRASHES!
very stable, was able to take off and land on a coffee table book with no problems.
doesn't hover perfectly still; has a slight drift. A/C in the house was turned off, so no air current.
Lots of fun and beats my Airhogs Stinger hands down!
NO CRASHES!


Gonna go practice landing on the ceiling fan. With it off of course, at least until my 3rd flight. LOL

Well I have 150 min (30 flights) on mine now and its still flying great, Took off the taill boom supports and added the second set of blades on the tail motor. shifted the weight so it creeps forward on hover but gives you faster FF speed. All in all a great toy.
