A very compact beginner US 4CH Coaxial RC helicopter came with lots of extras; stable to control, durable structure and above average flight time of 10min plus. Servos are built in with the RX, with the motor that runs them been exposed that can be easily damaged in serious crash. It is running brushed motors, and as I expected, power output is already decreasing. With Walkera brushed motors they usually dont last that long. Pros: Very small, smaller than Walkera 4#3B Stable Looks cool Value buy with lots of fun Pretty strong structure Cons: Non-separate servos No servo travel adjustments Poor servo quality; gets stuck sometimes on mine, with motors exposed. Life of motors Motors get really hot. And finally I dont like the swash plate & servo design. Basically right servo is controlling left/right, and left servo is responsible for forwards/backwards. However they are sitting 120 degree to each other both sitting at back of the swash plate, so when I press forward on TX, this heli goes north-right; and pressing left makes the heli going forward left. Yeah it can be confusing. They pretty much work independently. I believe both servos should push up when I want to go forward but its not the case.

it only happens when I turn the heli with hand, I think then the gyro misunderstands the physics of the heli thats why it asks the top blade to slow-down or stop spinning as top&bottom blades counter rotates and suppose to balance out.
I’m having the same top rotor issue. Occasionally they will not spin up, and it is happening more and more often. What did you do off-camera to spin them up?
@kamuro1976
I was having the same problem, took the heli back to my LHS to exchange it , only to find out that I had to mesh the motor gears to the main gears. Loosen the two screws on each motor, slide the motor closer, so it properly meshes and tighten screws. Repeat for other motor.
@kamuro1976
I think the 30 degrees to the right is just due to its swashplate design, so I guess we can’t change that. As for TBE, you probably need to check to see if your flybar is straight. I had very small TBE on mine (gave it to friend).
Use this one to practise nose-in side-in, then I’d get a blade MSR its beautiful and fly really well.
Hi! I got this one since 1 week. When I push the pitch stick forward the heli drifts forward and about 30 degrees to the right.
After this gesture it begins a huge and ever expanding TB (Toilet Bowl effect).
I was told to adjust the the trim – did that did not help
I was told to adjust the tiny screw on the 5in1 to adjust sensitivity – did not help either
Help – my poor heli behaves as though drunk….I’d like to get back to straight flying soon.
I think stability with such small craft comes from blade design. If you could imagine the wind as a funnel coming down you would see some produce a larger surface area at the bottom then at the top. The wider this cone shape is the more stable the heli’s platform is. This is just a guess but someone could do an experiment on different blade designs to let us all know the truth. Maybe Blade MCX’s name implies stability through the blade.
it is more for beginners really, heaps of fun indoor, and its cheap. once you can handle it well (am sure you can do it within days), you might wanna go to fixed pitch, a lot more fun.
it could be difference causes, need to check wires are not broken, then the motor. I wouldn’t say hair would cause such big problem, but yeah check every details would be encouraged as this is very small sensitive machine : )
If its the motor then obvious either upgrade to brushless or just get a brushed one they last pretty damn long for me.
Nice flight, I have bought my lama 2-1 9 days ago, I really enjoyed flying it but I have a problem with my top blades it slows down after a few seconds and it can’t fly anymore. I also noticed only the motor for the lower blades gets heated and i saw a hair in the swash plate bearing?.. i also had a few mild crashes and use a heavier battery 3.7V 700Ah 20C. I just presume and hope that I just need a new motor but i need your advice b4 I’m going to order it . Please advice, Thank you.
wow good video.
how long can hold in air?
your a terrible flyer ;p so reckless
dude.. i just fixed this problem.. play around with the adjustment screw on the flybar! you may need to unscrew it once.. =) hope it helps
my walkera rotors spins well but it can’t take off with a newly charged battery.somebody give me a clue on how to fix it please, thanks
@ernshengjoel It’s coaxial dude!!!!! oh god!!!!
@ernshengjoel
only happens when I turn the heli by hand =)

what happen to you helicopter top rotor blade?

no i haven’t replaced the motor yet. :o)
happy flying
so would u reccomend this heli then and have u had to replace the motors yet?
it could be difference causes, need to check wires are not broken, then the motor. I wouldn’t say hair would cause such big problem, but yeah check every details would be encouraged as this is very small sensitive machine : )
