I have been reading the heli forums & have seen many youtube video so I do understand the basics.

This video shows it fly perfectly in hands of experienced fliers

Now I am facing 2 issues which I am sure is due to my inexperience or may be something to do with fine tuning the trim controls.

1. when I start & want to hover the heli keep coming backwards my guess trim needs to be adjusted I tried  adjusting it but seems i am doing it wrong I cant keep it in still position, since as of now I am only learning scooting so I want to hover then go back & front & make a square.

Does the trim need to be adjusted every now & then as per flying condition or is it done once only?

2. The supplied battery & the charger seems to be a slow charger, i charged 4 hrs & it gives me 5 mins of flying time.

Welcome!
I have a 3ch too. Takes 30 mins to charge and fly time of 10 mins. How much did it cost you?
Mine moves fwd I recon its due to imbalance so i tried using small weights on the tail - cellotape. Dint work so will try little more weight once its charged.
The trim is only for yaw control ie. to stop the heli from spinning. (atleast in my case)

I have a similar Heli. 3 Ch Co Ax, same size and shape as the Volitation.

First thing first choose a large open space on a still, calm day to fly it.

Give it a good burst and raise it 6 to 7 feet off the ground. Keep your throttle steady, don't let it rise any further. It is important to give it a good burst and raise it high(I learnt that from this forum) because if you don't, and try to be too careful by keeping it low above the ground - you will cause more turbulence and backlash with the wind arising from the ground. This will cause the chopper to behave erratically.

Once she is airborne, she may start to go round and round. Don't worry. Just keep your throttle steady. With your right hand, start clicking the trim button repeatedly. you may have to experiment a bit here and see which side of the click is having more effect. After several clicks, the heli should start to stabilise. Now you need to guide her using the right hand side lever by gently adjusting left or right. In my heli, the forward motion is fine, but reversing causes it to lose height rapidly.

Above all, don't panic! If you do that, you will let go of the throttle and crash the heli. I am still trying to hover steadily for a while and bring the heli down accurately on a 12inch X 12inch landing pad. I am practicing my accuracy as of now.

Once the trim is adjusted, I don't think you will need to fiddle with it again.

To recap my two penny bits : Large open space, zero wind if possible, initial burst to gain 6 feet height, throttle steady (left hand), trim adjustment (right hand), direction adjustment (right hand), smooth flight for a minute, gentle descent to a perfect landing!

Happy flying!

Sujju, Anwar Sahab and all you other Heli Champs - STOP GIGGLING!  I am only trying to help!

30mins to charge??
I would love to get that charging speed, are you using some special charger or the one which is supplied with it in the box?

I will open the front & try to place the weight or alter the position of the battery so it can balance properly. I bought it for 2200/-

VC Thanks
its too windy here in Delhi so I am doing this in a 22x18 feet drawing room all empty.
I am able to raise it to 5-6 feet but by that time it comes back to me & I have to land it else it would crash on me or the wall, hence I posted the question as to why cant it hover where it started.

You have given me some good info I will fine tune the balance & then adjust the trim, now I understand as to why even after adjusting the trim it was still coming back.

mine is a small heli. 22 cm. yours is trex  7.4v so charging time will definately be more. 2200 is a good price. will buy that next as mine is strictly an indoor heli.

where did you buy it from?

I got it from Gaffar market Karol bagh
other shops in Zhandewalan cycle market & lajpat rai market in chandini chowk also have it.

This is the exact model in the box


this is how it looks

Hmmm... itsnot available here in bangalore

as per your suggestions I finally fine tuned the trim & I am now able to hover in the room at 6-8 feet but the heli does not say at 1 place of take off it still moves around to the room  with its tail rotating which indicates my trim still needs some fine tuning or the air turbulence within room is causing this to happen, I will test it outdoor & see if that solves the problem.

To adjust left right I have hard adjustment (a knob) & I also have the trim, as of now I have used the hard adjustment with zero trim.

What I want is that I take off 10 feet then hover keeping the tail pointed to me & practice left & right movements > front & back movements then land at the same spot where I took off.

Watching videos it seems Its too difficult bcoz mine is 3 channel heli & what I want to do would require 4 channel heli can some one confirm please?

You need to adjust the Trimmer wheel to correct this counter rotating tail. Once you've got it at a height of 6 to 7 feet and the tail keeps spinning, start adjusting the Trimmer wheel in either direction. That should take care of it.

What you are trying to do with a 3Ch Co Ax may seem difficult for us beginners, however, for the more experienced Heli Champs in our forum it must be an easy job. I guess we just need to keep practicing.

All the best!

Ok I will try soon your suggestions outdoors,
The battery life of 10 mins (Li-ion 7.4V 1300mAh) & 3 hrs charging is killing me.
I surely need more practice & would need 2 additional batteries.

Most online user reviews say that the supplied charger is a dud & recommend using a balancer.

I think its better if tried outdoors. My little heli gets pushed around indoors so it will be worse in your case.

Yes I thought so but Delhi monsoon windy weather wont let me do it for quite some time, i have been waiting last 3-4 days for a calm day.

I tested further indoors (outdoor is too windy) & found that sticking two 1 rupee coin in front the back movements is corrected, but it also adds weight, so whats better using trim Or counter weight? (full forward trim still not making full correction in my case)

Prateek13 suggested that I open the front & move forward the battery by 1 inch, is that better?

Now at least I can hover it correctly but when I take off the heli lifts off towards its right at 30° which I am not able to correct by left /right trim......do I counter balance on the left side to correct this?

Below is the radio of 9053
should this problem be corrected with hard adjustment knob (at top left L-R)

Are all the sub trims functional (A,B & C)? In that case you have a fairly good functional 3 Ch Tx as compared to mine. In what I have, B & C are dummies. It shouldn't be too difficult to trim a Heli with this Tx.......

Yes out of total 4 trims 3 are functional, but the B as shown in ur image does not.
that's the one below the (on left) throttle is dummy & does not function.

My guess is that B trim as marked by you would be called "roll" & that would require a 4 channel Tx

see the image attached for details

@Ranjan : the weather here is bad too. my 3ch heli got blown away when i placed it on the compound wall while opening the door

If the trim B works then you can get rid of the coins and make adjustments using this trim itself. My heli does not have this.
1. Did you try using this trim earlier? did it help or make any diff to the heli movements?
2. Using the trim or moving the battery is definately better as it does not add aditional weight. Any additional weight reduces flight time.
3. Can the 30 deg movement be due to downdraft?

I don't know but, my Heli gave no problems whatsoever in trimming and adjustment. On my Tx I only have the equivalent of 'C' Trimmer. She is quite stable and I am able to achieve a steady hover on a low wind day outdoors. She is not small, at a length of 76 cms. This is what I have:

VC what's the fly and charge time?

rajathv8
Trim B works but trimming it fully to up it still does not fully correct the backward movement hence I used a coin just for testing. I have read many other forums & can confirm that this heli is tail heavy & you need to make some adjustment.

As of now I have got 80% balance & I can hover it but it drifts right when it takes off so minor calibration is still required being a perfectionist I want 100% calibration so I can do what I want & not be in control of what the heli forces me to do.

3. Can the 30 deg movement be due to downdraft?
can you explain it a bit what it means?

hmmm then the best option would be to move the battery as it will solve the problem permanently.

When the blades rotate air is forced down. this air may be forced back at the heli by obctacles on the ground and can cause instability. Eg.. when near a wall the heli tends to get pushed away from the wall. Well this is what i understand, hope others correct me if im wrong.

I will try adjusting the battery now & see if that solves the problem.

As per your explanation it seems that the few things kept in the room are causing irregular air movements that might be the root cause, it should be tested outdoor to be sure but the winds wont let me do it as of now. 

Yeah thats the final decider. I tried flying in my hall but the heli seemed to move on its own. Ten i tried it in a 22ft X 12 ft space without any obstacls and it was much better.
