Here Here, I agree, these are a great deal as long as you examine them carefully and ignore the RTF label! Ready to fly after a good half an hour with a jewlers screwdriver kit and you can't go far wrong!

The Servos chatter on mine too, and I upgraded the servos to some 9g GWS and most of it went away! Still chatters sometimes when the TX batteries are a bit low, I have had better luck charging the batteries out of the TX and ensuring they are fully charged as the battery gauge on the Walkera TX's is pretty lousy!

i also have had servo problems with my 35. i replaced mine with hitech servos.
i would strongly advise anyone with a servo twitch or chatter, to resolve the issue before attempting to fly.
if the servo twitches at the wrong moment when you have a lot of power applied, you will crash.
...ask me how i know... lol

heres how we test for a bad servo (in the case of chatter). find a servo that is nice and stable, and swap the channel between the good servo and the bad servo. if the chatter follows the servo, its a bad servo. if the chatter stays on the same channel (ergo, the good servo is now chattering) then its a problem with the wiring on that channel, or a receiver problem. note: this is not factory advice, just something we came up with! if it doesnt make sense, please point it out, as we try to help, not give out bad info!

Hi - I'm a total heli newbee ... have a plane but never learned to fly it (crashed 6 times) .. well I was bored at work 2 weeks ago.. so I just bought a Walkera 35 ... received it today... The manual doesn't tell anything about how to adjust the Gyro or the switches on the back of the transmitter.. anyone has some informative links on getting started... maybe on the level of basic heli terms ect... the transceiver system is 6 ch... anyone knows what the 2 potentiometers and switches are for ??.. the manual is in english but the layout of the motor control curves sucks... can anyone explain or give links to what I need to know to (well maybe not fly) - at least not crash big time... What is the difference between the walkera gyro and the "better" onces from HobbyJanpan ?? I think I ordered the "medium" one - but got a walkera ... // BR - DK-heli-noob

hi noj,

this is just a suggestion from a newbee too. If you have not played with helicopters before at all you really should find someone that is familiar with them to look over your heli before you fly it for the first time. and of course while this person is doing that get all the info from them you can about getting started. you should have this person fly the heli and verify that it is in trim and ready for your to try it out for the first time. i would very very strongly recommend getting several hours on the sim, well past the point of wanting to try the heli before you give it a go. unless however you have plenty of extra cash for parts. as far as the switches on the back of the transmitter. if they are the same as mine they are servo reversing switches. if the one for your throttle is in the wrong position and you plug the battery in for your heli it may be at full throttle when you set the transmitter control for idle. this has been reported several times with these helis. also your transmitter may be set up for a strange mode. if you decide to give it a try be sure to be holding the heli in such a way when you plug in the battery that even if it goes full throttle it cannot take off or hurt you. this is another time when an experienced helper/teacher would come in very handy. on my 22D gyro there was a limit and delay pot. the limit was how much the servo moved for a given amount of heading change and the delay was how long after the heading change the servo started the move towards a correction in heading. if the delay was too short (or too long, i don't remember which...) the heli would shake its tail back and forth rapidly. i have read that you want to start with around 90 on each of the to pots and then start by decreasing the delay until the tail stopped wagging rapidly. then i am not sure about the limit part. someone with some real experience will probably chime in and give you the real how to for the gyro. have fun and be safe!

whoa, lol, thats a lot of fixing. let me try to help out.
there is no documentation, not that we have seen from 4 walkera products. in fact, you are luck to have gotten a manual in english!
hobbyjapan STINKS!!!! i would strongly advise that you not order from them. try helihobby instead, we have had pretty good luck with them
so far.

if your radio is same as ours, and i suspect it is, the switch at the top right is your 3d switch. you will want that in the up position. the pots serve no purpose that we have found so far. this is the same as the 22a, any purpose of those pots is a mystery to us.

we STRONGLY recommend that you go over the heli first, and this applies to any heli, any manufacturer. Look for loose screws/wires, check radio, etc.

update for all as to who "we" are. we are contemplating starting a business. it would be comprised of myself, my brother in law, and a friend of ours. i am a full scale pilot with little RC experience. My brother in law has a lot more common sense than me, and our friend has a ton of RC experience, although not with helis.

In our short sojourn with electric helis we have amassed a fleet of six helicopters, 4 of which are walkera products.

we have quite a lot of practice with repair and parts aquisition, not by intent, lol.

while so far, we stand behind walkera, that may change soon. hobbyjapan2000 is NOT recommended by any means, and walkera is working themselves into that range.

given the state of expansion of the hobby, and how much fun it is, and how poor almost all customer support is-we think of starting our own company. we wish to stock parts and advice and provide customer service, which is SORELY lacking. since we are not rich, we will probably have to endorse only one make of heli. though we have substantial experience with the walkeras, it seems probable that we will not be able to give our endorsement to them.

email haudy@haudy.com at walkera with your thoughts, as they have declined to respond to us.

for all of your help and support (even yours, chronus!) many thanks, and we will continue to try to help.

in return, i would like to ask you of your thoughts regarding our possible business venture.

PS: i receive 5 to 10 emails daily regarding the 35, my "copilot' gets around 10 a day. we plan soon to start our venture under the name "helighost.com"-it will greatly simplify our ability to go over requests and reviews, and also allow us to pool our knowledge much better than with the current system.

it is with great chagrin (tho no shame) that i can no longer recommend walkera products. we are now left to salvage the messes we paid for. its a fine enough heli, when you get it to work, however, that is a steep hill to climb. your thoughts on this are both welcomed as well as solicited. please leave the "its crap" comments out, only constructive comments are listened to. the rest we have a good laugh at.

Noj,

The two pots on the top are for the power/pitch curve adjustment. Out of the box you should not have to touch these, but when you have been flying for a whiel you may find the heli doesn't have much lift, or too much these are where you adjust it,

To enable them you switch the number 8 dip switch on the back of the controller, then increasing them will increase thye pitch angle in relation to the throttle position, after adjustment you should MOVE 8 BACK TO LOCK. As I SAY if your heli flys ok, dont adjust.

Also if you are learning I advice you leave the heli in normal mode, (silver switch at the top right), if you put it into CP mode (silver switch down) then the head will spin at full speed and the 'throttle' will just control positiv and negative pitch, in the mode the heli becomes dangerously responsinve in a novice had, and if you have trouble you will hit the ground with the head in full throttle, which at best will turn the rotor head into lots of little bit, or worse turn it into bits AND destroy your RX with the feedback surge (Or even worse hit someone!!, Remember always fly them away from people, and get some third party insurance just in case!)

As for gyros, to get the best from them, turn on TX, check everything is in the right position, throttle done, flight mode is normal (Your heli wont initialize the throttle if it isn't at zero, but best not to test this too much!! ) Plug the heli in and leave it for five minutes, this will allow the gyro to get its bearings, and to come up to temprature, the solid state gyros are sensitive to temprature. By doing this yoiu will find the heli head holds far better!!

sounds like a good idea for a business. the need is definitely there right now. I just wanted to add a comment about the walkera servo's. this has been said before so i am just adding one more experience. I had previously replaced the servo's on my walkera4 and it stopped chattering and was more stable to fly. I did not wait for the servo's on my 22d to fail as i replaced them all tonight with GWS servo's. no more chattering and the heli is much more stable... cheers!

OperaGhost,

Just to let you know, I to have started a business selling heli's, what I am doing is buying the Walkera heli's and going over them with a fine tooth comb before selling, as well as providing a manual we have written, a Flight trainer manual for each of the heli's, and providing first class customer support (which as you say is very lacking) The walkera designs are good (because they ripped them off of companies like GWS etc) but the build quality is bad, hence the fact we are 'bring up the standard, and making it as safe!'

Also we (my busness partners and I ) are developing some interesting electronic wizardry to enhance performance, battery life and most importantly saftey. We are currently at the R&D stage with alot of it, but are going into Alpha soon, so if you are interested in a discussion at some point PM me and maybe we can talk??

walkera servos are poor at best. my recommendation is hitech servos. good support, great servo, price is fair, to say the least.

bhermer & OperaGhost

Thanks a lot for some usefull information... I don't understand why the manual didn't explain what you just did...
Maybe they don't expect newbees to buy a helicopter before talking to a pro...

Have anyone tried to make a battery-pack from Nokia BL-4C 3.7 volt Li-Ion batteries ?? (3*3,7v = 11.1 volt (700mAh) or 3*3,7v || 3*3,7v = 11,1 volt (1400 mAh)...
I know it's not the solution for price - but I have lots and lots of those batts... so I just wonder if they can deliver enough power...

What is the differece between LI-Polymer and LI-Ion ?? can they be charged with the same charger ?

What is the typical powerconsumption of the standard #35 motor ??

The main difference is that Li Polymer is a more stable material, li ion is in liquid form and can explode on high impact!! I would suggest you don't use them for RC if you are making the packs yourself. You can get pretty cheap LiPo batteries, just make sure you get a charger that has voltage cut off, and never charge un-attended.

I am using a 11.1V 1900mAh pack in my 35 and it last for about 12-15 mins.
