While I was looking into batteries I got all paranoid about LiPo batteries failing and burning down the house. The RC forums seem to be littered with tales of LiPo batteries failing and either exploding or catching fire for no good reason. To protect myself and my home I bought a LiPo charging bag. That's a fancy name for a fire-retardant bag you but the batteries in while they're charging, and when they are charged, so that, if something does go wrong and there is a fire or an explosion, it remains safely contained. Word to the wise: don't put the charger itself in the bag. I did the first time and the charger must have over-heated because its lights were flashing some combination that wasn't even deciphered on the badly translated key. After being left to cool it seems to be working fine again now.
I had been using the simulator to understand what controlled what but it turns out to be an unsubtle model of the real thing. Hovering in the simulator is easy; a little power, a little rudder and there you are hanging in the air - real life is another story. But I'm getting ahead of myself...
I knew that, being older, I would find learning to fly a little tougher than your average teenager weened on video games so I decided to follow Radd's School of Rotary Flight. He subscribes to the slow-but-steady school of thought. Basically, you keep the helicopter on the deck and learn the controls before you even try to hover. In theory it's the best way to learn; in practice it's dull. You have to expend 9 batteries worth of flight time without ever leaving the deck. Movements outside a 1 foot square constitute a 'crash' with the punishment of having to reset everything if you stray outside that area. I thought this was supposed to be fun?
The other obstacle I encountered was that the helicopter always wants to slide left which makes the ground exercises tricky unless you hold the aileron stick hard to the right much of the time. The simulator does a poor job of representing this effect. This drift is especially pronounced on a low friction surface (like the tiles in my kitchen) and the helicopter skates and drifts all over the place as soon as the skids get remotely 'light'. It seems that the helicopter starts to drift before the cyclic controls have any effect on direction.
Which leads to your first crash. I say 'crash' but that is something of an over statement; 'heavy landing' is more accurate. I was over soft ground with the training gear on when a breath of wind pushed the helicopter behind me and threaten to topple it over. I was only three feet off the ground so I did what any beginner would do; I panicked and cut the throttle. I must have come down pretty hard through because the blades weren't level after that and spinning them up caused them to clip the tail boom. It's a scary thing to see your new toy bent out of shape although it turned out that I'd just popped a bearing out of the center hub. It didn't take long to diagnose or to fix.
Harder to diagnose was a transmitter 'problem'. The ET4 transmitter has Voltage Indicator lights and the manual says "When the last light turns red and flash, the dry batteries are in low capacity and need to be replaced". Either the transmitter eats batteries or the batteries that shipped with it are crap because, after playing on the simulator a bit (the transmitter has to be turned on if you're using it as your controller) and my 10 helicopter battery cycles the transmitter's bottom two lights (red and yellow) were the only two lit. 'No problem', I thought. 'I still have some time left before I need to change them according to the manual.' Wrong! With the green lights out the transmitter won't bind to the helicopter. As this coincided with my 'heavy landing' I saw the transmitter having no effect on the helicopter and assumed the worst - that I'd burnt out the 4in1. After much fretting and fiddling I tried fresh batteries in the transmitter and all was well again.
So that's where I'm at. I still can't fly but, given enough room to drift around I can hover ... a bit... a very little bit. I've found the manual and simulator to be inaccurate in places. My helicopter is no longer virgin - it has some dirt and scuffs on it but I haven't had to use any of the spares that I ordered yet. To answer my original question, yes, we're having fun already even though I've got a long way to go.
To charge the helicopter,connect the helicopter to transmitter.There is wire with plug from the life hand side of the transmitter.Turn on the transmitter and red light bright indicates that the helicopter is charging.You can also charge using the USB cable.And more..
