After the terrible crash our Lama V4 suffered last week (lost control at ca. 10 meters high, free fall on concrete basketball field, debris spread in a radius of 3 meters), we decided to get some help from professionals before flying our helicopter again. From now on Orango will pilot our E-sky machine, while Tang will wait for him safe back home. Wish all of us good luck!

IF after:
- adjusting the gain
-adjusting the proportional
-trimmering on the radio
your bloody lama V4 is still rotating on itself in the same direction, before exploding do as follows.
Open your radio controller and look inside. Dismount the elevation cloche and examine it. Dismount the motor ratio powers control and reassemble it so that you can trim it (it is quite tricky to do it but you can tilt the control a little bit so that is not biased anymore). If you understood what to do and you did it correctly, now with just the aid of the trim you can adjust the piros rotation!!! Set the lama up! Your helicopter will now take off and land in the same position.
Pain and destruction to the guys who assembled the radio controller originally!!
hi guys ,im extremly new to this heli thing but loving it. i have just received a lama v4 for xmas super stoked.
Its only been attempted to fly a few times ,the heli just wants to bank left as soon as it legs leave the ground i have tried using the trimmers but seems to do absouloutly nothing. so therefore had a few stacks taken on some minor damage i.e landing feet blades tried swapping to the new blades but no difference was seen. i have even tried adjusting the the proportional pot too. but didnt want to go to far into that untill i am sure the heli is not dodge to start. any hints or suggestions
I would really love to help you…but until now i didn’t find any FINAL SOLUTION to Lama problems
What I can suggest you is to make all the settings with a fully loaded battery and with the Lama flying at 1 meter above ground. After you find an acceptable set up, learn to fly it and to correct it “live”.
I tell you more. today I tried for the first time the inner shaft in aluminum. The copter doesn’t stay on its axis anymore. I will have to replace it with the old and fragile plastic one.

Can someone please help.
My 13yr old son bought a Lama v4. Before he managed to fly it, the receiver burnt out after charging the battery and turning on, and attempting tolift. The receiver was replaced, he flew it for a few few hours. Again, after charging battery, the receiver starts to smoke and burn again. No-one knows cause, supplier trying to blame him for misuse, but he was careful and followed instructions.
Please help!
I am sorry Carol we never got this problem. What about trying with another battery (and a new receiver)? You could make this test in front of the vendor, to convince him you don’t misuse the Lama. good luck!!
Hi there,
The supplier is telling us that the helicopter was crashed with blades turning. We know this is not the case. How can I prove this? Will resistance in the blades prove it?
Are you using the original battery of the Lama? You can easily show the vendor that the helicopter didn’t crash. For what I now, using the 7.4V battery gives no problems. But if you go up to 8.4 Volts, some cases of burning are reported.
hi
i just brought my lama v4 in thailand , it take off great in thailand i was flying it around , when it was time to travel back to the uk , i packed my lama v4 carefully and couldnt wait to get back to uk to show my friends , but when i got back i took the lama v4 out of box , charged up the battery and tried to fly my lama v4 , now it will not take off , i did all the things i did in thailand but still not work , i did notice the green light was on at start of powering it up but full power the light stayed on red , is this right?
please can you help me get my lama v4 to take off
thank you

I thought about you’re problem and I’ve no real answers.
I suppose your lama was not in your hand luggage.
The Lithium polymer battery is really fragile. It shouldn’t get compressed, I suppose it shouldn’t get temperature stresses.
Can you check with a voltmeter/ampermeter if you can really charge it?
The light on red means two things: or low battery, or that you start the copter with the radio on with the throttle active. Or that there are other problems I dont’ know
Let me know!
You may want to invest into a 2.4 Ghz Esky Lama V4. It seems as though your helicopter lost control because of possible receiver/transmitter problems?
Most Esky Products now are transferring to the 2.4 Ghz system, which will hopefully prevent your “accident” from happening in the future.
Hi!
I am trying to fly my new lama v4 but i’ve not got any success so far because heli is leaning either backwards or to the left side… what i thought it shall be able to take off from the spot it stands? I tried trimmers but it doesn’t change much at all. Any ideas?
Thanks for you help in advance.
I had the same problems at the beginning. Trimmer changes were not enough, I had to work with a tiny screwdriver on the screws on the receiver.
Read here how to do it: http://blog.ifrance.com/lamav4
Thank you very much for your reply!
I went on that website you gave me, but unfortunately I couldn’t find my problem. Could you please advice where on the website it is. Or may be you can email it to me, or give me your email?
Thanks in advance

You need A LOT of patience to set it up properly. Follow word by word what is written there and good luck!
yeah, thanks a lot!
Are u sure it’s solution for my problem? Because, when I try to take lama off the ground it’s going sidewise by the it’s body but not by tail rotating somewhere?
So in other words, why i want from helicopter is getting up in the air straight instead of getting around making movements sidewise (not clockwise)…
Looking forward for your reply.
Hi Roman,
First thing to say is that when you take off, if you are not at least 80cm above the floor, there is the so called floor effect that destabilize the copter. Same thing if you fly in a small room, close to walls, the wind streams created will perturb the stable flight.
Second, be sure that the battery is not moving a lot in its place to have a good and stable balance.
Next, if I understand correctly, when you take off, and then do not touch the commands except throttle, your copter goes backward or on the left as if you were pushing the corresponding command. If that’s so, it means that the swashplate is not horizontal when commands are in neutral position. Then, you have to use the trims to adjust it. If trimming is not enough, unplug the link between the servo and the swash plate corresponding to the command you want to adjust and srew it up or down to have a swashplate perfectly horizontal when transmitter commands and trims are in neutral position. It should be fine now.
Well, I do not see other things to check, except perhaps tracking of the blades and vibrations due to unbalanced blades and stabilizing bar.
Hello,
I bought the Lama V4 some months ago and flew since then..
I had an upgrade on th battery – raiden 7.4V 20C and used this for a few times.
That´s curious, but the bouth battery(original and raiden) are not working anymore…i give the fully charge but the heli doesn´t go up anymore…
The red light on the receiver blinks as soon as i start flight!!
Can someone tell me what could happen here?
What´s the battery shelf life?
Is this raiden good suggestion for lama V4 or there is another better option?
thank you
Good day , i would like to know , with taken off must it be on the ground or put it on something higher , i cant even lift off , and how do you hover
It should lift off from any place, ground or table or whatever. If it doesn’t, or batteries are too low or engines are gone.
To hover you need to calibrate balance properly or continuously adjust the position find the needed motor speed – any wind will make it very difficult.
my lama 4 wont come off the ground and it spins realy fast to the right power is extreme when throttling however will not fly for no reason. what can i do. tony
I used loranablog’s suggestion to fix the trimmer problem (always turns in one direction) on my Lama’s transmitter, however now there is an issue that the trimmer doesn’t fix the turn rate – it turns one way with low throttle and turns the other way at high throttle. Do I need to mess with the gain and/or proportional? If so, what does each one do? I still can’t tell after lots of meddling.
Also, for those of you who are mystified by the controls, I discovered that my aileron and elevator servos were hooked up backwards. After switching the connections the controls seem to work as intended.
Finally if your heli is not taking off or seems to require excessive power to take off, it’s probably because the angle of attack on the rotor blades is not the same. Look at the heli from the side when it is spinning at a low speed, and if the two blades on either rotor are not in the same plane, then you need to twist and adjust them. This reduces vibration and also makes both blades produce the same amount of lift.
Dear Andrew – I never noticed such problem and it is a long time I do not fly it anymore. Sorry, no answer to your problem.
