Lipo, Outrage 2s 5000. The heli balances perfect with that pack.
You can burn over a gallon of fuel with no recharge too

Think I am going to buy this one :
OUTRAGE XPRX 2S1P 7.4V 3600mAH SPEKTRUM /JR FUTABA RX

Because my charger is limited to 5A... so a 5A lipo is a bit too much.

Not easy to find a good shop that sells Outrage batteries :s

you could also buy 2x Outrage 2s 2500, and with a regulator like the Dualsky VR8L.
That reg has 2 inputs and 2 outputs.
This is my own exact setup on my X90.
There are pics in my gallery showing how the batteries sit.
The Dualsky reg is excellent, adjustable, linear, and cheap too.
Zero issues with it

Yes but I don't really like 2 lipos, seems to be more difficult to manage.

How long can I fly with a 3600mah ? (Enough I suppose )

Sorry for my ignorance, this will be my first nitro heli... A 2S1P gives 7,4V but the servos, gyro and receiver only support 4.8V (sometimes 6V) what do I have to buy ?

The DualSky seems to only support 5V-6V.

5-6v is perfectly fine for most good quality servo's.
Just beacuse it says 4.8v does not mean you cannot go to 5 or even 6 if it can take it.
You WILL need a lipo regulator anyway, and with 2x output leads, you will never crash because 1 lead comes out of the RX.
Really the only EXTRA electronics is having 2x packs.
But if 1 pack dies, the other will safely fly your heli.
On 5000mah I get about 5 litres of nitro through before I need a charge.
I am using ACE DS1015 servo's on 6v, a Futaba GV1, a Spartan DS760 gyro with a Futaba BLS251 servo.
Anyway, Im just giving you options, what you decide to use is entirely your choice

So there are 2 leads that plugs in the RX ?

I have "only" a T7C with a R617FS.

I will be a problem, will it ?

No, you dont have to use both leads, you can just use one if you want to.

So, I can plug two batteries (input) and use only 1 output lead.
Good to know

I will probably do the same as you finally

Gorn,

I opted for the Outrage 2S 5000 pack with the 8717's in our X90, I never worry about running out of juice

I just bring (2) charged packs to a fun fly and were good for the entire weekend, plus the Outrage TX 2600 pack in the 9303, Steven goes a month without charging the radio

They are perfect huh. I hate having to change out packs if there is no need.
The X9 is plenty light, and even with 5000mah packs is lighter than most.
Nothin like lipo's in the TX either. Just have to watch the voltage lol

Yeah,

I setup a fried with a TX pack and he left his radio on at the field for over an hour, it dropped to 11.7 volts and he was amazed, I did tell him to charge it just in case

I usually don't need to change out the pack, just like to have an extra one with me.

I have accidentally left my TX turned on in the case for 4hrs.
I nearly pooped when I remembered lol.
No probs, all was well.
I had visions of smoldering JR
