I'm building a blade CP Pro version with microheli CNC head, CNC frame, and twin tail motor, with E-flite 20 AMP ESC and Eflite 370 Brushless motor, also the E-flite Head-n-Hold Gyro. With carbon fiber main, and tail blades. I'm installing a berg 7 rx also.

I have the E-flite 11.1v 800mah 3-cell li-po. Will this battery be enough power for this heli.

Also if not and I need a more powerful battery with more mah's.
And will my Standard li-po charger charge it.

Darkhorse has a nice page that helps compute power req's
see http://dhrc.rchomepage.com/calc.htm


As for the charger, I would get a better charger then the one that came with the Blade kit. I dont think it really is all that good at balancing. Based on its design it looks like it just charges until 1 cell hits 4.2v and then stops.
If you do gets a new charger, check the charging leads PRIOR to plugging any Lipo into the charger. Some chargers are expecting the charging leads to be reversed from what the EFlite charger uses (never cross the streams )

It will work. But to make it shine, I would use the 1320mah.

What is a good li-po charger. And will the 1320mah hurt any of my eletrics, not to much power is it. Just want to be on the safe side. Thanks

1320 will be heavier, 800 is good i think or tp910's, get the dd tail, it's way better than stock.

Outback,

The only way it could hurt your electrics is if you went past 11.1v (ie 4 cell lipo)

from 800-1320mah is gonna be good if they are 12-20c rated. Think of it this way.

mah is the ammount of time a battery will last. But you have to counter this time with the weight you add to the heli. More weight is less time, more mah is more time. Somewhere along the way the weight will defeat the time more than help it, and weight can make your electrics work harder to achieve the same/like results.

How much will that whole package cost?

So far I got a G tied up in it. I only need charger,balancer/ and one more battery. And then it set's on the shelf till I can fly the P out of the stock one.

P.S with some left over parts, it all adds up.
