What battery and charger would you recomend for this Heli? what would the max size weight and voltage be? I have found a bunch of batteries at http://www.helihobby.com/html/batteries.html but I have yet to recieve the Heli I bought the base model to learn on.

i have a tp 1320 mah 11.1v lipo and a celectra charger (e flite) works good for what i use it for. i may recommend a higher amperage battery, around 1500-2000 mah for longer flites

I unlocked the 8th dip switch and turn the PLT and PZT knobs, but still having a problem. What are the settings for the other dip switches on the back of the transmitter.

Thanks

I had some trouble getting the heli to hover at first.

First of all make sure you use a good charger to charge the batteries, mine worked heaps better when I stopped using the crap charger it comes with.

Then I adjusted the linkages to get a bit more pitch. I've found that the best way to adjust the pitch is to adjust where the collective servo attaches to the collective pitch rod (the one that goes through the main shaft). If you loosen the screw you can slide it up or down then tighten it back up again.

hI guys! I am a newbie..just got my walkera # 36 with brushless motor....there are two battery connectors in this unit...one is for the receiver and one is for the speed controller....do I need another power supply for the receiver .. I noticed it still working although the battery connects only on the speed controller ......? tnx.....

You plug the battery into the Brushless ESC, It will provide power to the reciever. The other battery connector coming out of the reciever is for when you use a brushed motor, as the brushed motor uses the recievers built in ESC.

I just got my Walkera 36 and it is Sunday ! anyhow does any one know which of the 2 chargers provided with the brushless package is the one for the Li-poly? One of the chargers says Li-Ion on it.. the other one has no labels.
Also in my box there were crumbs of what looks like some type of food which i thought it was pretty gross did any one else get anything funky in the package? are these guys eating while packing the helis? LOL ...

If I were you I'd buy a quality charger for your LiPo's, like the Duratrax Ice, Triton charger, or something similar.

Didn't get any suprises with my #36.

One comment I must make - I am of the opinion there are a lot of complaints about the ability to fly this bird because people who buy any ready to run model make assumptions they should not. I race cars, fly planes and helis and have built models and have bought read to run kits as well.

All people who buy ready to run kits should treat them like 'build your own' models - eg work your way progressively through each part of the helicopter - hell take it apart and reasemble so :
1 - You know how it works and how to identify issues if they arise
2 - More importantly, you go through the all important model tuning phase. Eg I have not seen anywhere near enough mention of balancing in these forums. You helicopter will fly like ****e no matter what you do if your bird is out of balance. Start from the rotor controls then move the rotor rod, out to the flybar then on to the paddles and finally and most importantly learn how to balance main rotor blades !!!....these buggers will generate most model instability (provided servo's are ok) and most are not balanced out of the box, no matter how good they are. It only takes a percentage of a gram to make a smooth flying heli fall from grace and make stable flight much more difficult. One great way to observe heli vibrations is to leave the trainers on - they will highlight vibrations.

Its all good and well mastering a flight simulator - but you must also master the art of making your model mechanically sound....

Saying that they are a ****eload of fun and for the price I am impressed. I have hooked up with 3 mates and we all have walkera birds (a #4 and 2 #35's) and we are all doing well....!!

Very well said. I am new to this hobby. I bought a #36 with a brushless motor for my first heli. I got what I expected. I went through everything and made adjustments that were necessary. I got familiar with how it works and made sure the controller was set up correctly before I decided to try and hover. Yes things needed to be adjusted and the controller was not set up for a beginner. So far I am very happy with the product. I been spending time on the simulator and time trying to hover. Yes I have crashed all ready. I do not have a lot of room to practice. If I make a mistake I will hit something. I have broken a few parts, but it was my fault. The radio is working great. I have no issues with it at all, but I must have broken the gyro when I took a hard crash. I just ordered a futaba 401 gyro for its replacement.

All and all I am very happy. Just spend some time and read up on the #35 and get familiar with the chopper before you run it. It’s a great chopper for the $$$. It is not ready to run out of the box. It will need some fine tuning. One thing for sure it that I am glad I only spent $250 and not $700 - $1000

Checkout http://www.milehighwings.com/pic_cables.htm as this guy makes PIC cables especially for the walkera 22A and 35 models. I have the 35 and assume the the controller is exactly the same as the only difference in the heli's is mechanical (eg rear belt drive) - the Collective/Throttle mix would be the same as would the rear rotor angle control.

I would contact walkera to confirm that they use the same controller / electronics setup as the 35, then contact milehighwings and get a cable from them (or even better get them to confirm it on a 36 ).

I have ordered one - cost $34 AU including shipping - well worth it. You can also use the controller as a controller for planes etc - cheaper than buying a dedicated sim set !

Rathalian,

Are you sure it was AU$34? It appears to be US$35 which is about AU$47.

It's probably still worth it, I just wanted to make sure I wasn't paying too much.

Yes your right - my bad

- and u are right re worth it...is a great help. If only it would balance my blades for me LOL

Hi all,

Just got my 36 (with brushless and 2200mAh Li-poly battery) on Monday and as I had a few days off work thought I'd give it a go.

After checking it thouroughly all seems fine, everything checks out all else adjusted. Just one problem:

Is anyone else experiancing a power problem? The battery is providing sufficient power for litteraly a couple of hops into the air before losing power. A volt meter reads 12v+ but there's not enough juice for anything better than "light on the skids". The pitch range is not too great (7degrees at 100%) and it's not the charger as I'm using a decent one not the supplied.

Thoughts? Battery, ESC or motor?

Hi Stephsf,

My #36, with LiPo, NiMh and stock motor arrived today.

I charged the NiMh to 15v, and the LiPo to 12.6v. (Using a DVM)

After some 'fettling' to try and balance out the travel on the various controls I spun it up.

Not too bad, and reasonably balanced.
So, to try and get some lift...

Whiiiizzzzz, the blades start cutting as the pitch increases... all is looking good, then just as you describe, the power vanishes!

The NiMh is great - if only for a few minutes. At least it gives enought power to lift off the ground!

The LiPo is rubbish!
If you give it hell, and floor the throttle, you get the obvious kickback, and a little hop, then nothing, back to the floor.
It's like the internal resistance of the LiPo is about 100ohms!
(That would also explain how hot it gets).

Anyone else have any advice?

Would charge cycling the battery a few times help?
Or is it just Walkera batteries?
Or even the ESC?

Is the LiPo supposed to be exactly square? (mine it slightly rounded).

Help :-(

I had a similar problem until I set the throttle trim to the center. I only have the brushed motor in my #36. If I have the throttle trim set all the way down I won't get full throttle. Hope that helps.

Hi I have the 36# with the 2200ma Li-po and the Walkera 3200KV brushless I too get the same problem I have not been able to lift off the ground as It loses power very quickly. I was just about to order a decent Battery charger but I think the problem is the battery itself.
Also the motor gets very very hot.. wonder if it needs a cooler plate around the motor..?
has anyone been able to fly this heli sucessfully?

I have hovered mine, but I'm still in the learning stages of flying. The 36 seems like a good heli, Ive had no problems with mine.

I'm glad I didn't get the walkera Lipo's with mine

for you guys having trouble with power loss and a hot motor and battery. It sounds like the rotor drive system is causing way too much drag and is using all the available power the battery and motor can give just to get light on the skids. if this is the case you will need to find out why the rotor drive system is dragging too much. it could be that the motor to main gear is meshing too tight and binding and or the tail drive system is causing the drag from not being set correctly. I don't have a micro heli with a belt drive tail rotor so i don't have any advise to give on that. the clue is that the motor and battery are getting too hot. something is most likely not set up right.

My Motor (brushed) gets very hot when flying, and my batt (LiPo) gets warm. But I am able to hover at least at eye level (I haven't tried going any higher).

My gear mesh looks good, not too tight.

Guys,

Thanks for all the help. It looks more like the battery now, it feels "squidgy" when pressed and now won't take a charge at all. I've been in touch with the suppliers (RC Toy Shop) and they are sending a new one - however, this is probably going to be of the same build standard. Fingers crossed though, but I think I'm going to have to buy a new battery from here in the UK.

cptsnoopy:

Good general advice, but the meshing is just fine, set so that the motor drive gear teeth are about halfway into the valley of the main gear wheel, not in so far that it binds, not out so far that it slips. The drive belt seems about right too.

Ok, looks like my battery is suffering the same fate as yours... Squidgy and not giving out power - I trickle charged it at 0.2C to make sure it was carefully charged.
My eBay supplier is no longer responding to e-mails!
Looks like I should have gone to the hobby store

On a happier note:
I used the NiMh, and managed a 4-5 second hover (about 3 feet up), with a successful landing afterwards - great stuff!

The next hover wasn't quite so good :O
It was only a gentle crash, but it took the blades, pitch adjustment thingi (black) on the end of the blades, and most annoyingly the pitch adjustment servo in it's wake!

The blades I had spares for, the black bit - super glue fixed...
The servo, I didn't even know was broken until my Heli went mental.
All of the servos started twitching, and would hardly let me control them.
Time to upgrade to an HS-55!

This leads me onto my next topic:
Heatsinks.
I have worked out what causes the receiver to go mental like this - the voltage regulator (which was trying to supply power to the mangled servo) overheats.
One of two things then happens:
1) The regulator cuts out, causing temporary loss of RX
2) The heat generated causes the control IC to overheat, with the same sympton.

So, this crash has led me to do some pro-active twitch prevention - an ex 486 heatsink, chopped up, and trimmed so that with the cover of the RX removed, it sits nicely between the two ICs (1 FET, 1 Regulator) and the body, dissipating all of that lovely heat away.

I'm hoping that this will give me slightly longer use out of the Walkera electronics!
