Eagle 50 lipo Battery upgrade?
Anyone knows of any lipo battery that I can upgrade to for more flight time that would actually fit the heli's battery compartment? Currently I have 11.1V 800mAh/10C, it's the stock battery that it came with; I'm only getting about a 3 min hover time out of it!! And a burned out main motor

I don't know odf one, but Andy should know from Exceed Rc. I'm sure that he will answer to this post. I would like to know to, because I need more time too.

check your head speed. if you blades are spinning uncessary fast it will burn out you battery faster. Your take off should be a little over center stick.

Yes there are batteries with more maH (milliamp hours) that will fit.
Milliampere-hour:
A battery capacity or rating. A battery that provides a
current of 1000mA for 1 hour is rated at 1000mAh (or 1Ah).
You might consider swapping the position of the receiver and the battery
on the main frame, keeping the receiver oriented in the same position.
If you are going with a more "powerful" (heavier bigger battery).
This will better balance your helicopter.
Understanding Lipo batteries
http://en.wikipedia.org/wiki/Lithium...olymer_battery
and
http://www.batteryuniversity.com/
You will be exerting more energy trying to hover.. takes more juice.
Moving in reverse.. tail coming towards you, uses the most energy.
Forward flight most efficient... blades give lift. Here's some links
that explains blade lift, more complicated than one would imagine.
It discusses autorotation (not really achievable with the Eagle 50
except if you are flying at a high altitude and your battery runs down,
thus you blades are still spinning at a low speed and you can maintain
forward momentum as in a dive... ie the blades spin giving lift).
http://en.wikipedia.org/wiki/Autorotation
also what is known as
Transitional Lift and hovering efficiency.
http://en.wikipedia.org/wiki/Translational_lift
and also
Cyclic Pitch
http://en.wikipedia.org/wiki/Cyclic_pitch
After you fly... and the battery runs out, let it cool down completely
before recharging. Try charging the battery in the evening or before
you go to work or school. Then try to recharge again before you fly.
Do NOT leave your charger unattended as a safety precaution.
A normal charge for me takes about 95 minutes.
Try another battery... you will want another one anyway eventually.

RE: Eagle 50 lipo Battery upgrade?
I just noticed that you are flying near Denver... as in
"mile high City" ....
You are going to have problems with lift in thinner air...
I am at sea level and "fat" air. You should try and find
a local RC group and see what they have to say about
your thinner air conditions.
Increasing the pitch may solve some of your lift problems.
That is the knob on the top right of the receiver....
also it's good to take rubber bands and secure the switch top right
to the "Normal" position so you won't accidentally push it to the "3D" or "1" position.
also when you replace the motor.. make sure there is just a micro of wiggle room
between the motor gear and the big gear on the helicopter... I just eye ball it...
wiggle it a little... you don't want to have the motor jammed up against the big main shaft gear.
Also make sure nothing is rubbing against the big main shaft gear... that includes the
bolts that hold the motor to the main frame.
