Pulling to one side when taking off!

by pixelthis » Wed Jan 05, 2011 6:18 pm

I have just received my CopterX 450 ME V2, I have followed everything setting the radio up and the gyro, lock threaded every screw one by one. However I am having some problems taking off, the helicopter seems to pull to one side which if I keep going will end up with the blades hitting to floor! At first it was the tail spinning which I fixed with a little trim, but I can't seem to fix why it's pulling over to one side! I don't dare take off with it doing this!

Any help please?

The obvious question is have you levelled the swash at mid, low and hign stick?

Your gonna need to do LOADS of homework my friend. Please be safe, and to be safe, you need to have a bit of setup knowledge :wink:

You will need a swash levelling tool to have a dead accurate swash, but you can learn the basics with an eye level swash :wink:

But again, YOU WILL NEED TO DO MORE HOMEWORK, cos just a level swash ain't gonna get you flying :shock: Read up on setting up a RC helicopter to gain a bit of understanding before you go fly.

You my want to think about purchasing a PITCH GUAGE too :wink: 8)

Hi Pixie.

I don't know what you do know.

Helis are always going to go their own way at take off.
Your job is to anticipate and control it.

How much experience do you have and have you done your homework?

Hi Pixelthis

I have a fairly large PDF document that runs through the entire mechanical and electronic setup of a 450 clone. It's based on the T6 type radio, which if yours is from CX it will be a derivative of (although it's valid for pretty much any radio)
If you want it, PM me your email and I'll send it to you. I found it an invaluable tool when setting up my 1st 450.

cheers

I don't think I am taking off quickly enough which makes it more of a sway to one side!

Iv been trying to hover in doors and can't because well it would hit something so, ill take it out tomorrow and give a good take off I guess then ill see when I try hover if its really out?

Just as a matter of interest, what's your previous flying experience?

And you're right, flying a 450 indoors is a very bad idea - these things bite hard

Pixel,
+1 :D to Dunnys advise.
Without a knowledge of basic set up then my advise would be that you need to be very careful, an incorrectly set up heli is dangerous. If you google Chopperaddict there is loads of information on there. Ian ( Chopperaddict ) is a top bloke and realy knows his stuff. Im not sure where you are in the uk but I would seriously encourage you to contact Ian and arrange for a 1 to 1 day with him. He will make sure you set off on the right tack and save you hours of endless headscratching, most importantly he will give you advise to ensure your heli is safe to fly.

Now I know what you are thinking but I dont get any comission from Ian...LOL without a basic understanding you will quickly lose heart and a shed load of cash buying spares. You may also hurt yourself as these little brutes can bite hard.

Please don't try and fly a 450 indoors!

Unless you have a huge flying area you are asking for trouble.

We are talking about blades that will cut flesh to the bone!

Do not underestimate the danger of theses machines!

Pixelthis,

I'm not really qualified to give advice as I've yet to maiden my 450 (this coming weekend, honest), but I would suggest you view Finless Bob's build videos.

I have a rather large sitting room, Anyway I took it outside for a quick session, managed to hover for just under a minute or so a little shaky on the back end did a quick search and turned down the gyro sensitivity, back up in the air was OK! Did a 3rd flight and well crashed, into a bin completely lost control of the hover big gust of wind...

It has bent the stabilizer bar with the paddles on which was rather easy to straighten out then realised one of the balls has broken off which controls the pitch, I'm rather shocked to find most of the head is plastic seeing as I spent nearly £200 on this, I used a little of the glue supplied its OK now but something is not right and am not going to risk flying it till I find a replacement head / part.

Image Is what broke!

Is there a better replacement head for this model every link / part is plastic, or that individual part?

Edit**

I believe it is this part:

PIXELTHIS

SERIOUSLY :shock: :shock: :shock: DO SOME HOMEWORK BEFORE YOU HURT YOURSELF OR SOMEONE.

If you have JUST REALISED that the head is plastic...... You have obviously NOT done a flight check, let alone look over the bird for defects ect :shock:

Please please, before you do some serious damage, understand a bit more about your heli.

I'm not trying to put you down personally, but it's chap's like yourself that give this hobby a bad reputation.

Mate, you gotta understand the dangers of the heli FIRST, and how to set it up. Please do more research and gain a better respect for yourself and others and their property :wink:

Sorry to grumble, but it's gotta be said :shock: 8)

Thank you for the advise, it was checked over and it was less then 10 inches from the ground! I am very aware these bigger helicopters can hurt someone!

I really, sincerely hope that that was a joke about glueing the see saw mixer arm (the part you circled in the picture)??

You cannot glue these parts if they broke. You are really asking for a nasty accident my friend...

Although you may think that you've straightened your flybar, it won't be dead straight and will contribute to instability. Get yourself a few of these as spares as well as main shafts, feathering shafts main gears and main blades. There's nothing more annoying than waiting for parts on a good flying day.

While your waiting for replacement's, do plenty of reading and as someone has already suggested, watch Finless Bob's set up vid's over at helifreak. Do yourself a BIG favour my friend 8)

+1 to what neomagic said. Those are the essentials.

Just check which feathering shaft it uses - the older plastic head HK's (and presumably CX) used 3mm shafts while the newer HK's use 4mm shafts. Best to use Align shafts and gears, they are so much better and available from Heliguy real quick

Totally agree with MrDunny`s advice here, and sometimes it needs blunt remarks to make someone think.

Dont know if anyone noticed the crack in the arm that had broke? but you can see where its glued, imho, that heli is totally unsafe now, and should be grounded completely until proper parts have been fitted.

you say you wont spin up while its glued, so why bother to glue it? honestly, i hope you dont.

Many many thanks for all the help guys, I am going to be reading lots and I shall check out Finless bobs videos! I have ordered a metal replacement part hopefully should be here shortly, hopefully will have better luck next time! It's amazing the difference between coax and these, I can fly my coax all around the house no problem what so ever, this I had trouble just hovering, I am trying to find a more active club, the one I currently am in have literally one flight a month and no heli flyers apart from one 14 year old and his raptor 50, maybe then can find someone with some experience can give it a good look through.

Does anyone know the range these helicopters can go? The box has no manual or nothing!

PS: the simulator included with this heli is a complete joke, its like super mario brothers!

Range ? , easy one, it will still be under control far after you have lost sight of it, hmm by then, it probably wont be under control lol.

There's a heli only club, called Phoenix Rotors, that meet every Tuesday in Arnold, they have a field out near Farnsfield. I will probably joining this club.

The manual for the CX450 is one of the pdf files on the CD you will have received, it's not very detailed so you will be better off downloading the Trex 450 manual available on this site.

As for spare parts, you could probably get a complete CX450 Pro TT from Hong Kong or China for a third of what you paid (I did). And while you wait for it to arrive you will have plenty of time to strip down and loctite every metal to metal screw and bolt, just dont get loctite on your plastic servos (see I'm still learning too) :)
