Esky Lama V4
This page contains information about the Esky Lama V4, a fun, 4-channel RC
helicopter that can be purchased inexpensively from locations such as
I purchased one of these and have been enjoying it a great deal!

A useful review of the Esky Lama V4 written by Daniel Switkin in 2007.
It still has some good information, but it is a bit light on useful links and
some information is not up to date (e.g. my helicopter did come with
instructional videos... in mandarin, I think, as well as a PC-only software
simulator for learning.)
BoomTownHobbies.com, from which you can by XTreme Hard Blades. You'll
need these much sooner than you think because even though the Lama V4 comes
with a spare pair of upper and lower blades, you'll probably trash both pair
before you manage to learn to fly in a oval path. I'd also advise you to buy
a set of the unbreakable landing gear as well. The ones that come with
the helicopter will break and you can't fly it without them. I also busted my
canoy shell, so I bought an Xtreme shell. (Mine
broke when the copter fell from about 50 feet onto grass -- my own fault. The copter was fine, actually. Only the canopy broke.) This place has wonderful

small velcro attachment. I added my own velcro. Having a second battery is

How to Rebind the Transmitter and Receiver
One thing I discovered is that if your throttle stick is on the left, you
have a "Type 2 Transmitter" and folks elsewhere on the net recommend changing
the servo reversing switches on the lower right side of the transmitter to
up-up-down-down when seen from left to right. Ok, did that... charged up
the battery and I was ready to fly, or so I assumed.
But, I could not get it to work!
The transmitter and receiver are new RC technology that pair to each other,
similar to the way a bluetooth headset pairs with a mobile phone or a
The receiver inside the helicopter has an LED that would flash red and
green alternately. It will be solid green when it is paired with the
transmitter. I could not get them to pair!
The "manual" is rather poor at explaining the procedure, and surprisingly,
the discussion forums I found were also not very helpful either. It seemed
though that a lot of people were having the same difficulties.
It turned out in my case that I needed to unbind and rebind
the transmitter and receiver so that they would pair again. Here the
instructions in the manual were even worse, if that is possible. :-/
To "unbind" the receive and transmitter:
- Turn the transmitter off and unplug the helicopter batttery, but leave
the battery inside the helicopter as if you were about to fly it.
- Carefully pull the small rubber rings off the pins on each side
of the helicopter body. DO NOT PULL THE PINS OUT!!
- Place the rubber rings into a small container so they don't get lost.
- Carefully lift the sides of the front shell of the helicopter off these
pins and set the front shell aside.
- The transmitter is the white rectangular object in the front. DO NOT
ATTEMPT TO REMOVE IT!
- You've been seeing the red/green LED on the right side of the receiver
as seen from the front.
- There is a very small pushbutton on the front of the receiver -- this
is the unbind button that you will need to press... but not yet.
- Plug in the battery (even though the transmitter is not on).
- Look on the left side of the receiver and press and hold the unbind
button until you see the orange LED flicker quickly.
- Now pull the throttle all the way back toward the bottom of the
transmitter. It is the unsprung control stick -- it will stay in that position
without you holding it. Turn on the transmitter and look again at the right
side of the receiver.
- If all has gone well, after about six to ten seconds the LED that was
flashing red and green will become solid green. You can test this by moving
the throttle very slightly away from the bottom until the blades begin to spin
just a little. Then slide the throttle back down.
- If the light becomes solid green, then carefully replace the front shell:
- Be sure not to damage or kink the tiny wire that comes from the front
of the receiver
- Also make sure not to push the pins back into the body when you slip the
front shell back. It seems much harder to get the shell back on than to get it
off, but if you line it up by eye you can get the shell back.
- Replace the rubber rings to keep the pins from shifting.
- You should now be able to fly! In my experience, once you have gone
through the unbind sequence, the transmitter and receiver won't need this
procedure again even if you unplug the battery and turn off the transmitter.

- Top Blade Doesn't Spin
After a particularly hard landing I found the top blade had lost all power.
The bottom blade spun, but not the top one. I thought I had lost a gear or
broken something and I took the shell off to investigate. What I found was that
the entire drive shaft had slid down inside its plastic sheathing between the
motors and the large drive gears on the bottom had slide down so that one was
no longer in contact with the metal gear on the motor. All I did was pull the
drive shaft up to re-engage the gears and everything worked great.
- Helicopter Won't Go Forward
Sometimes the helicopter won't go forward. It just wants to go backwards.
At best you may get it to stay approximately in the same position even with
the tilt stick all the way forward. The most likely cause is that the battery
has shifted backwards slightly. Make sure it is all the way forward in its
compartment. Even the position of the battery connectors can make a slight
difference. I like mine inside the front shell and forward of the battery.
- Transmitter Controls Do Not Work --
Green/Red flashing LED on Receiver
- the battery on the helicopter is charged and connected, and
- the battery meter on the transmitter shows there is plenty of power, and
- the throttle stick (the unsprung control stick) is all the way down, and
- the transmitter doesn't seem to affect the helicopter when you advance
the throttle control stick, and
- the receiver on the helicopter is flashing green and red
You need to rebind the transmitter and receiver.
