Santa brought me and S107G, which I've duly charged, and just tried to fly.  Sadly nothing is happening!  Frown I turn the remote on, get a green (solid) power LED.  I turn the heli on and get nothing - the LED at the front of the heli does not illuminate at all.  Is it DOA or is there something I'm missing?

If you've charged the heli and not getting the LED to flash when you turn it on, that's definitely DOA.

Thanks.  That is very disappointing!  Re. charging the heli, I've charged by USB, and the light on the charger cable is glowing just about as bright when the heli is plugged in as when it's not - that's all I have to do, right?

not saying this is the problem but some usb leads have been faulty-have you tried charging by remote?

Thanks for the suggestion re. charging from the remote.  I have tried it, the remote light turns red for a few seconds, then green again, which if I understand correctly means the heli is fully charged.

Anything else to try before I send it back and find something esle to do on my holidays!?

Look inside to see if any wires are not connected.

 

Could easilly have a broken connection somewhere that'd be easy to fix, or could just be a blown-out DOA.

 

If it turns out to really be DOA, get them to give you a new one- don't flat out return it, you'll end up loving the new, working one.

Just a note,

I have 6 chargers and they have different light info,

one charges but the light only comes on when charged, no idea why, but when charging anyway I use the timer on my phone and set it to go off after 40 mins, it seems to work. 

It says, say something here --- so I have

Would you guys accept an F103 Fire Wolf as a replacement for an S107G?  They cost more, but are they really better?  Looks slightly more complicated/sophisticated, more moving parts.  I'll be learning, so bound to crash plenty - does that just equal more broken stuff and time waiting for parts?

There is always a danger of breaking things, by all means buy what ever you like but the main thing is, start off slowly with the flying learning curve.

Just had a look at it on youtube and seems like the motors give a lot of power so be careful with the throttle and,  --- take off slowly.

The Firewolf is meant to be a 4 channel heli, but really just drifts,if you want to up your flying to a proper 4 channel go with Nine Eagle helis all 4 channel helis are much harder to fly,so be prepared for crashes and repairs,however that is the next move up in this hobby

Turns out it was DOA, dead battery.  Joel at minihelicopter.com.au provided  great customer service - fixed it, sent it back the same day with another S107G for parts and some batteries.  Not the cheapest around, but great to deal with.

The other thing with more moving parts is that they equal more things to break.

 

The S107g and its counterparts are very elegantly designed to have the fewest moving parts practical. Heck, fewest major components to make it fly possable! You can fly these things with real bullet holes in them! (well, if it's the right bullet in the exact right spot... the plastic nose, but anywhere other than the battery, and back of the metal frame part, with a .22 of course...)

 

The only things that affect the ability of these to fly are the motors, (2) tail motor, (1) gear sets, (4) main shafts, (2) blades, (5) motherboard, (1) battery, (1) and wires. So, excluding wires, you have 16 parts to be concerned about for flight, and 4 of them are the equivalent to changing the oil in your car, and 1 like the antifreeze. So, effectively 11 parts to be concerned about. Compair that to a 4 ch that probably has an additional, oh lets be kind, and call it 5. So, probably about 16 major parts on the 4ch.

 

The number of parts also is exponentialy growing with the number of channels- 2ch ones would have 9, then 11 on 3, then realistically 14 on a 4ch, then there's 6ch, so about 23, then 36 for an 8, and then you hit 12 with probably 74, going by the forumula.

 

And, does anybody know exactly how close my sipherin' is?

I can't speak for the number of parts, but I can say that isn't an exponential increase in the number of parts. Significant, yes. But not exponential.

could be a logrithmic increase... that'd be insane!

 

I was only rough guestimating, but if it takes the number of connectors, gears, extra motors, and servos that you'd think it would to get these things to have absolute full function, it would leave a large number of parts.

 

Whether true exponential growth, or figurative isn't really exact...

 

heck, it could be 2-9, 3-11, 4-14, 6-18, 8-24, 12-32.
