I don't really no what to do lol

[Bonsaisupet]

Well first I will say hello, and I will also say I have a king3. Right befor I get into my questions my budget wouldn't go any feather and the deal with misses is once I brought one I am nit getting any more so I brought the best I could with tthe money I had lol.
First I don't have a clue about rc heli's at all, I brought this king 3 second hand needing 1 servo changing with was supplied with it, I have put it together and today for the first time tried to fly it, but it won't even come off the ground ?? I understand that this is the pitch of the blades but how to change it I haven't a clue ?? Also the blades lean forward the more I power it up ?? And last but
Not least the tail spins around the more I fire it up the quicker the circles get ?? This I also don't no how to sort?? I have tried to adjust things by the
Controller but it doesn't seem to have much effect a little but not enough if that makes sense ?? Please help

Mike

Hi and welcome to the forum ... The tail blades spinning faster than the main blades is normal ...As for the rest what Tx did you buy with it ?? .. And also it does not matter if your on a budget for your first heli as long as the missus does not mind you buying spares lol ...

Make sure that all 3 servos of the same make and speed as it sounds like one is not if its pitching forwards ... Is there nowhere near you that you can take the heli to for them to have a look over it for you ??? ... TBH its better if someone that knows what they are doing has a look for you then they can tell you what needs doing to it and set it up and guide you through it all as its easier to show someone how to do something than it is to explain on a forum ... Also join helifreak and watch finless Bob's vids ... worth there weight in gold for all helis that use 3 servos to control the swash

Thanks for the reply buddie, I shall try and find somewhere to take it and get help the o ly trouble is I live in Devon and well there ain't many people down here lmao. Can you tell me what a tx is ?? Sorry I am a total bigginer in this lol

[Cagey]

Stop right there Mike.

I'm with Mike W here. The learning curve with helis is way too steep for anyone to take on without resource to a fat wallet. Don't want to discourage you buddy, but you will have an expensive bag of trash on your hands unless you get an experienced flier to help you. Joining a club is the way forwards my friend. There's surely one close to you where ever you are. You're right in one respect, being in this forum will get you all the best advice available for success. Good luck with it mate.

Get the feeling what Mike the OP is saying

A) 'the blades lean forward the more I power it up'
This could be interpreted as gaining more negative pitch (Certainly would explain the lack of lift)

B) 'the tail spins around the more I fire it up the quicker the circles get'
Sounds like either the gyro is reversed, or tail drive belt is reversed.

A video of what's happening would help

[Bonsaisupet]

Hi, thanks for your replys, I shall make a video Tomo of what's happening, and post it on here, I do have loads of spare parts with it, if it breaks then I shall fix it I just ain't allowed tO get another one lol, I have tried looking on the net for clubs close to me but the nearest is about 40miles away that I can find, I shall make a video of as much as I can and post it up to show you all and how it's all set up and moving etc, and once again thank you

[Bonsaisupet]

Hi sorry guys I have just got home from work, I shall hopfully get a Vid up Tomo, or later on this evening

Tx is short for transmitter. There will be people close to you. Helis are very popular. Ones like yours are difficult to fly and easy to crash. Even if someone gets it all working right you would be very lucky to get it off the ground without crashing it. You can start looking at it and working out what all the bits do. Nothing complicated, just seeing what moving the tx sticks do to the servos. Make sure that all bolts are tight. Any bolts going into metal need to come out and be loctited back in. Range check the tx and check out the batteries. As someone said there is a lot to learn.

You can get an idea for how difficult it is by using a flight sim. There are free flight sims. The best known is FMS and that will work with a joystick, but it is better if you can connect up your tx through a usb interface.

Don't be in a rush unless you like spending money and repairing things. Think about insurance as well. If you can't stop yourself from trying a takeoff don't try to hover. Just spool it up, let it take off and let it land straight away. Just a hop. To make things easier you can tilt the heli slightly to the right rather than on the flat, as helis hover with the blades dipping to the right. If you take off from the flat, the heli will roll to the left and crash unless you make it roll to the right.

Hi
As has been said before in posts log on to finless Bobs site and check out the setup videos. Depending on your Transmitter (TX) make and setup this could be contributing to your problems, you could also have servos connected wrongly (ie pitch & elevator on the wrong channels). You really need to understand and recognise what you are looking at & what kit you have etc.
As you bought the set-up second hand with a faulty servo etc it may have been crashed and rebuilt by someone who didn't know anything about it. It always worries me when someones sold a heli with a faulty item (in your case a servo) but they have supplied a new one with it. Why have they not fitted it themselves and sold it RTF. As has been said take it apart loctite it and put it back together 1 step at a time you will learn how it goes together and how it should work.
You will need to learn this as no matter what you will crash and you will need to rebuild it... Fact
Keep us informed how you get on.

Hi, thanks for all the replys, hmm the replys make me wonder about giving this a go now lol
So first things first strip it down and lock tight it all back up again, I have been watching
Videos about these things and how tO set them up but non in great detail just a general idea, I shall have a look at this chaps videos that you all are suggesting and analyze it as much as I can to learn what I cam here's a little video of it on my table last night not flying but just watch each lever does and then what happens on the heli, sorry for all the links not sure witch ones the right one lol

Can't view the vid right now, but will take a look later when I've got the laptop turned on

It's not that difficult once you've got used to it. You don't need to understand maths or physics or electrics. You do need to know that there is no time to think with a heli. You have to know what to do as soon as it happens. It takes time and practice on a sim or an mcx or msr.

One thing I found useful is to take a closeup photo of a part before you take it apart. There are often more ways of putting it back than you thought.

If you think its difficult then thats a good sign. There are different bits that you can think of separately. So you only need to sort out...

The tx (programming)
The rx (range testing and connecting the servos to the rigght channel)
The esc and bec ( Does it get hot)
The gyro (Does it work, is it in heading hold)
The head (Is it connected up right and not sloppy)
The motor (Does it go round the right way and does it get hot, are the bearings gone)
The main gear mesh (is it too tight)
The tail drive belt (tension and condition)
The training undercarraige (Do I have one)

Where can I buy the essential spares like the main shaft and feathering shaft, main blades and tail blades. Main blades should be glassfibre to start for about £3.

[tiddler]

Ahhh right, cant really tell from that vid what's doing what without seeing the sticks and the swash both at the same time, so as to be sure their moving in the right direction.
One thing I did notice is one of your servos sounds very rough

Basically,
When you move the right hand stick forwards/up, the swash plate should tilt forward.
When you move the right hand stick backwards/down, the swash plate should tilt backwards. (This is elevator control)


When you move the right stick to the right, the swash plate should tilt to the right.
When you move the right stick to the left, the swash plate should tilt to the left. (This is aileron control)

When you move the left stick forwards\up the leading edge of the main rotor blades should (While holding the fly bar level) rise/point slightly upwards, as in the left hand illustration shown below. (This is positive pitch and generates lift)

the opposite should happen when the stick is lowered, as in the right hand illustration shown below (This is negative pitch)



You also need to check the tail rotor is spinning in the correct direction.

When the main rotor head is spun clockwise, the tail blade nearest the front of the heli should be travelling upwards into the downdraught of the main blades (Anticlockwise when viewed from the right hand side of the heli)

From the video it looks fairly good - The two posts from cj and tiddler above have some good advice.

The one thing I will say about the King 3 is that it's supposed to fly out of the box - there is very little setup you can do on the TX/RX that comes with it.

They are however very difficult to fly, watch the idle up switch make sure its in 0 (normal) and the knob at centre position. You will need training gear on the first few flights, youll need lots of space because it will shoot off quickly - And no more that a foot in the air until you 'get the feel' for it.

Oh yeah - you need some new batteries in the transmitter lol

Good luck.

Lmao thanks guys, I shall get on when I get home and have a fiddle, thank you very much I am. Honestly greatfull for the advice, I shall get back to you all on how I get on lol
