450 clone build

450 clone build

Press right rudder and the tail output shaft should move along the tail rotor shaft in towards the main tail casing. Push left rudder and the tail output shaft should move along the tail rotor shaft outwards.
You need to ensure that this correct direction of tail servo is setup first before you plug your tail servo into your gyro.
Once you have your tail servo centered and the tail servo arm is at 90 degrees and your tail output shaft is in the centre if the tail rotor shaft, then and only then are you good to plug the tail servo into your gyro.

Also make sure your gyro is sensing in the correct direction. You can check this by pushing the tail to the right ( as you look at the heli from the back with the tail pointing towards you) and the gyro should make the tail output shaft move in towards the tail rotor casing. As if it is trying to input a right rudder command to compensate for the movement of the tail and vice versa if you was to push your tail to the left the movement of the tail output shaft along the rotor shaft would be the opposite to the above.

Grant.

Well as my 450 is just about complete I thought it about time to get some more practice in but my flying seems to have gone all the pot haha so I thought let's start frome the beginning and got out the good old msrx and started flying around the house I also read that quads help with orientirian and stepping up to cp Helis so with a few searches I found this little feller the hubsan x4




what a laff this thing is perfect for In the house and also does tricks I wish I had read the advert a little better and relised it was a v1 and not the v2 but never mind a couple of videos showed me what mods needed doing eg earplugs as feet to stop motor from smashing into the ground the v2 has addressed all the issues but never mind still awesome fun and hopefully teaches me some things to build my confidence ready for the 450

also would there be anyone in the durham areas willing to give the 450 a once over and set the giro up for me as I don't want to crash trying hahaha

Hi there is a few of us that fly at Durham on the football fields next to new college if weather is ok we are out most weekends am sure one of us could help . Jon

[Markmark.123]

That's spot on could you let me no if ya ever up on a Sunday morning

[dodeye]

No probs mate will let u know on this or send me your phone number can text you when we are out ��

Right am just on trying to sort out the pitch and I carnt get it to have zero pitch at mid stick and when I set the + pitch it isn't the same as the - pitch I am using me dx6 is the something am missing here haha

Roughly my approach is to find the physical limits of the swash movement so I have the servo to swash rods off and pump the swash up and down.

This gives me the total pitch range (though full cyclic deflection will limit that in reality). I find the centre of that range. I hold the swash level at that point.

I have the servo arms set to 90° via the radio at mid stick already.

Then I adjust the rod ends so the rods meet the servo balls. I also check that the rods are much the same length unless meant to be offset like on my atom.

I know I've said it already but your best bet is to watch Finless's setup videos. If you're having problems with CCPM you most likely haven't.

Trex 450 SE and general build videos are here - HeliFreak

CCPM part I & II are the ones you need to watch for this step.

You should be able to get a total pitch range of around 20°.

You could work the other way round and take an average to find your midstick zero. Say top end is +11° and bottom is -9° giving a range of 20°. Middle of that range is 10° which lies at +1° so find that with your pitch gauge and set the rod lengths accordingly.

Well it is finally finished so I thought I would put up the spec and a couple of pics

trex 450 clone kit by mystery ( aliminium and carbon fiber kit )
mystery s0009 metal geard servos
cys s9257 rear servo
titan 720 giro
carbon fiber tail fins
hobbywing 40a esc
hobbywing motor
orange reciver
blade 450 skids
hobbyking glass fiber main blades




all that is left to do is get up the field and get the giro set up hopefully maiden flight goes well haha

[Rich23]

Looking good there Mark.

Rich

[helijohn]

Sweet machine.

[Grant85]

Looking well Mark! 😊 how much has the total build set you back then if you don't mind me asking?
Cheers,

Alright grant moment of truth

kit with all electrics £55
reciver £7.95
skids £2
canopy £5
blades £4
other bits and bobs £15

total =£88.95

[Grant85]

That's awesome and amazingly cheap! And I bet it will fly sweet as too!
Despite what many people on here say about clones, for that price you really can't grumble. I hope the maiden goes well and I will be looking forward to seeing the flight of you video it.

Thanks for sharing.
Cheers,
Grant.
