Did you run the motor in?
Do you know if your battery is fully charged?
Ps be careful thinking upgrading things is going to make them stronger, almost any heli that makes contact between the tail and the ground is going to shear something, plain physics of this world i am afraid, if you start putting metal gears on they will remain intact but the next thing down the line will be damaged and usually costs more than a pinion or gear.
The best way to get around the fragility of these machines is to do everything to avoid crashing, ie using sim, using training gears,not flying out of your ability. think twice act once,if it shakes on the ground dont think it will disapear in the air,it,ll proably get worse(this the reason my 22a never left the ground and i got to many other heli that just fly so dont have time to rework all the faulty bits in to something that is acceptable.

Alright well I ordered this Walkera RC Helicopter off hobbyjapan2000.com and got totally scammed this helicopter is total junk. I was even in total contact with the company before during and after I ordered this product the whole time being told about how there defective rate was super low because of how they fly there helicopters three times before being shipped. Well this was also total BS (Bull S@#$!!). First off let me just say that I would never recommend doing business with hobbyjapan2000 they lied to me the whole time about the helicopter as well as charge me for the return postage on the helicopter after a MILLION questions about how the damage to the helicopter was probably my fault. Anyway I am no idiot to helicopters I fly them for the US Army currently so I might be new at the RC world but defiantly not the idea of helicopters and when I got the Walkera it looked great and I was excited about flying it. So being my first time dealing with RC helicopters I went to the local hobby shop because I new the owner and we put it into a weighted stand and turned it on. As soon as we turned on the radio the servos were acting crazy like moving on there own and adjusting pitch on the blades almost like we were getting radio interference from somewhere so we moved to a different location a couple blocks out of town still the same thing was going on. After about 10 min of just letting them freak out they started to calm down so we felt comfortable about seeing if we could get the Walkera to flight speed. Keep in mind this is still in the weighted mount and it was a good thing to because we didn’t so much as have the helicopter to 1/3 of its flight speed when it started vibrating so bad we thought it was going to flip the mount on its side. So we put it back to idle and called it a day I have packed it up and am now trying to get my money back but having to fight about that also. If we would have let that helicopter get to full flight speed or even half for that matter it would have shaken its self apart it was not only a safety risk but not what I agreed to when I ordered it, so this “ready to fly” helicopter was far from it. My recommendation is to avoid the Walkera as well as Hobbyjapan2000 all together save yourself some time, money and the headache of dealing with a bad company. Hope this helps.

Hi chronus,

I didn't run the motor in, didn't realize I had to, I have run the heli for 2 full charges now, is it too late?How do I do this if not? As for vibrations, the heli seems fine, all balanced out great.

Battery is good, I bought a decent one to replace the NiCAD with a good charger, I never even used the NiCAD as the flight time with it was 5 minutes even in the manual (probably means three!)

Can you tell me what the two dials on the TX are supposed to do?

Thanks

Ben

Ben i cant tell you what those buttons do as they are unique to your heli i think but i am sure i saw apost in here explaining http://www.rcuniverse.com/forum/Walera_Helicopter_No%2535_or_No%2522/m_2627203/tm.htm .
re running the motor! it is getting less common these days as brushles and liths take over but any brushed motor needs to be run in if you want max power and efficiency out of it.
You need to do this when it is unused the reeason being that when the brushes are new they are not bedded in tot he shape of the commutator,when you dont run in a motor you can cause arking on the com wich can lead to glitching in the heli.
To run in , it is notrmally just run unloaded(out of the heli) with a cuople of aa batterys for an hour or so, when the brushes ar bedded into the com they will give more contact between them and will not arc, will be more efficient and will have more power.
A quicker way to run in the motor is with the same aa batterys and run the motor completely submerged in a glass of disstilled water for about a minute each way, take out and shake/dry then run the same again in a cup of cleaning fluid or wd40(electrical). then relube the end bells with a tiny bit of oil.
with a brushed motor you will notice the speed and efficiency drop quite rapidly as the comm picks up carbon material from the brushes making the contact less.
When i used brushed motors(in heli especially) i would run the motor in wd40 every ten or so flights and it would be like as new again.

How do you know your battery is fully charged?does the charger say so or do you test the voltage with a meter? you need to know this before you start to break the chopper down and find your problem.When working with heli and trying to solve problem you must start with the things you know must work and do work so they can be illiminated.

Well, just received mine. I like it so far, but I haven't gotten it off the ground yet. I read about breaking in the motor and have done that. I'll post again when I've had a chance to try it. I am also going to try my own receiver, gyro and speed control in it, if anyone needs an extra transmitter, receiver, or gyro, email me.

Well, I think I found the problem with mine, something was binding my motor, I was hovering on sunday, 95% throttle at about 4 feet high, just practising hovering and the blooming thing all of a sudden shot 25 feet in the air!! it was like the brake had been released!! unfortunatly I kinda lost control on the way down and mashed the main prop when I landed/crashed

causing £30 worth of damage!!

I took out the main motor placement screws and there was scoring on the end of one so I guess one of the screwws was to far in and grinding on the top of the rotor, finally it ground away and released the motor!!

May be worth checking this when you get a new one!

Here are a couple of posts I placed in another forum - they generated little interest before maybe useful for someone trying to make a decision.

Okay, it has arrived!

No import duty - item was sent via EMS post (trackable all the way through the parcelforce website).

It appears to be functional and includes everything I asked for. Here is a list:
Heli (4 servo's, reciever/speed control, separate gyro (says tail lock).
Transmitter
NiMh pack
1050 LiPo pack (was supposed to be 1200mAh but only £11!)
NiMh Charger 2 pin
Lipo Charger 2 pin
English (ish) instruction manual.
A VCD of somebody flying a Honey Bee 2 (a bit pointless!)
A training undercarriage kit
Spare blades (different to the original set)
Simulator cable
2 extra different pinions
3 allen keys
Spare double sided foam pads
Cut out cardboard pitch gauge.

My only gripe so far is that the blades that are included (both sets) are plastic rather than the carbon ones shown in the ebay adverts.

The quality of the thing seems okay, the servos look really cheap and I don't know if they will last long! The packs are charging as we speak!

I have tightened up a few loose bolts and adjusted the main motor mesh as well as running it in a little outside of the helicopter.

Ill let you know when I take the plunge and fly the thing.

chronus, dont take my comments personally-i am sorry you had a bad experience with walkera (hobbyjapan2000 most of all). I also have, and seek to make my experiences both positive and negative available to all.

a note regarding setting the motors up, this should be done with any direct drive system, btw...

the walkeras at least seem to come set very 'tight'. i did what the instructions say, tho (and chronus will love this...) you are lucky if you get instructions in english...
1st, loosen the tail rotor mount. move it back, away from the motor EVER SO SLIGHTLY!!!! you dont even need to see it move back. just take a lil bit of tension out between
the gear teeth and the tail boom gear.
Retighten.
Next, loosen the motor up, it should shift. again, it should shift only slightly.
retighten.

Some say you should also do the tail boom itself, i have not found it necessary. The goal is to get the gears to mesh, without burying the teeth into the valley of the next gear. Just loosen it up a bit. I did this with my 35 before running it first time, and a friend of mine did not. the difference is amazing. his would spool down in 2-3 seconds, whereas mine would take 10 or so seconds to spool down. we adjusted his, and its now the same way.

now, a question for you guys...i have a bad servo 'twitch' on my 35, it stops when the xmitter is turned off. it doesnt seem to affect it when its flying, as in, if there is input, it stabilizes. but sitting on the ground 2 of my servos twitch to no end. i dont know if this is due to interference, although i doubt it. The same friend has no problems like this with his 35. again, it doesnt seem to matter when there is control input-but i cant think of this 'twitch' as a good thing!

any ideas?

again, let me restate my opinion as to walkera products. the product is fine, just needs tweaking as do any of these helis. the problem is the distributor (HJ2000).
and chronus, all of our boxes say HELICOPTER, not PLANE, lol.
j/k keep the opinions coming guys-lets just keep them constructive.

LOL, you mean you got instructions with yours! i got a piece of paper with a photo of a chopper, thankgoodenss the picture was in english

A piece of paper in betwen the gears is a good way to set the mesh, you really want a tiny wiggle in between the gears but the sound and the feel will direct you to the right spot, smooth and quiet as possible.
Try relocating your aerial, to get rid of glitch.
Constructivelty i would try and avoid these choppers in the first place but yes like anything it can be made to work if put the time and brains into it.(sometimes this not good for a newbie though)

its almost funny...i like these helis, but the distributor STINKS! The 22a a, is NOT a beginner chopper, in my opinion.
now for the funny part, the 22a came with a manual, in some language that i cant understand. my friends 35 came with an english manual. my 35 came with both!
...but nothing for the radio or gyro!!!!

i still like the 22, when its all gotten in one sock it will be a really nice heli. the 35 has a much easier learning curve, and should be just as capable as the 22a, maybe a bit slower due to weight...

i think i got one of the servos lined out, there is a pin that was loose. a preflight check of servo settles it down. but the other, still jitters. im working with rerouting all the connecting wires, as that seemed to help with the first issue. still workin on servo number two.

to reiterate point about gears...a piece of paper would work fine, if one doesnt have a feel. Im a machinist, lol, so i go by feel. the point of this operation is to make them loose, without making them sloppy. its prolly sufficient to simply loosen and retighten. The helis are good, in my experience, but the supplier is not so good. take much care when ordering. stay on them via email. after the 22a, we specifically requested, several times, to NOT set them up. just leave the heli in the box and ship it, as ordered.

a rank newbie can set them up better.

happy flying!

I've had the D22 for 3 months and have been very happy with it. I kind of get bored with the D22's limited capability and not challenge enough. What would be the next good helicopter to get? D22A or D35?

wow, this is a hard question....

remember, its just my opinion...

i would probably go with the 35, or even a honeybee 2.

the 35 is a totally different head/hub system, also the main gear is different.

the 22 is nice, but that damned main gear is crap, even tho i like the heli. I would go with a 35.

feel free to email me with specifics, and ill tell you what (little) i know. Ghosty1@gmail.com.

happy flying!
