Bare with me Im new

Im sure after you read this question you will probably be looking like this. or doing some of this Well here it is what is the gyro, what does it affect and were is it on the heli.
Thanks

Hello Banshee,

RC heli gyro or Radio controlled Helicopters gyroscope is an electronic
device which is used to stop the body of the helicopter from rotating around its own axis.

It is usually fitted between the tail
rotor and the receiver and senses any change in the rotational movement
and compensates the force moving the angle of the rotor blades hence creating
a force in the opposite direction nullifying the effect .

I have included a video just so that you can get idea how the gyro works. I hope this helps.

Good Luck ,

Valentine

is the gyro also known as the yaw control sensor? or something? are there any brands that are good but wont burn a hole in the pocket?

Most lower end gyros are perfectly ok...the more you pay the better the performance...so they say.

Try CSM for gyros....fair prices....the lower end type like the CSM 180 wil ldo the trick....I use a CSM 200 which has been fine so far....it copes with the heli being flown upside down....its a bit limited with some aerobatics....but for general flying around its been very good.

Futaba are slightly more expensive....I have experience with these.

Most beginner type gyros are 'heading hold' some are just that...others can be switched between modes so the tail is much more softer so aerobatics are easier.

I would get a basic heading hold gyro....preferably one that can be switched....if you get the gyro sense wrong you can simply flick a switch to sort it out.....the CSM 200 for example...has to be unstuck from its foam pad....and restuck...upside down.

Gyros cancel out 'yaw' or uncontrolled tail movements....as you change pitch on the main blades...you increase 'torque' (twisting motion) which tends to upset things....the flyers of old flew without gyros....compensating with pure tail control....but ways were soon found to make life easier....enter the gyro.....you still have authority over the tail control...as such.....the gyro cancels out all unwanted tail movements.

Very clever piece of kit....the later type Piezo type gyros actaully got the technology from camcorder stabiliser systems....to reduce 'shake' as a result the older type gyros are obselete....though some folk still use them...nothing wrong with that but they scoff more battery power....(rotating parts) Piezo is solid state....so are the later types of gyro.

so to make the tail follow the front of the heli i need a head holding gyro?

Hi Dharvin.

You don't need a heading hold gyro They are just better for beginners than a standard no HH one. With a heading hold gyro, you dont really need to worry about the rudder, allowing you to concentrate on the other controls, throttle/pitch, elevator, and ailerons, because the gyro will be holding it in whatever position you put it in. Or so my instructor told me when I was learning!

Good luck
