Newbie - Heli advice

HarryD

I'm new to the RC scene so I decided to break myself in easily by picking up a Heli.

At the moment I'm ramping up on the simulator.
I've a few questions before I get used to things been wrong;

- How does trottle relate to collective pitch ?
- on the simulator the trottle always seems full
- in reality is the trottle conrolled by a switch or a joystick ?
- I take is the left joystick on the TX is for collective pitch/rudder control
- Leaving the right joystick for cyclic pitch ?

TIA,

- How does trottle relate to collective pitch ?

This depends on how you set up norm/idl up1/idl up2.
Starting of you will normal use norm, this should translate to a 'fairly' straight line for both your throttle curve and pitch curve, i.e when you raise the throttle stick, your throtle will go from about 10% (engine at idle) to 90%/100% (engine up to near full throttle). The throttle stick will also act as you collective, so at the same time you raise your throttle, your collective (in norm) should go from about -4% (at bottom stick) to 0% (at mid stick) to about 9/10% at full stick.
Idle up 1 and 2 used for 3d flying. this will mean your throttle curve will be a V-shape, i.e. bottom stick = 90/100% throttle, mid stick = about 50% throttle and full stick = 90/100% throttle again. With these setting and more - pitch at botom stick on the collective (say same at full stick : -10,0,+10) you will be able to invert the heli and still have power when your throttle/collective stick is below 50%.

- on the simulator the trottle always seems full

This is most likely becasue you are using a govener on the sim. this sets your engine/head speed is at a constant RPM, thus you dont have to worry to much about your throttle curve. You should be ableto disable it on the sim and you will see what I mean.

- in reality is the trottle conrolled by a switch or a joystick ?

With out govener, its controlled by the stick, with govener on, once your throttle stick goes past 25% (i think) it will enable and put your head speed at the RPM you set. You govener should be hooked up to a channel in your reciever which should translate to a switch on you Tx. That way you enalbe and disable the govener by flicking the switch.

- I take is the left joystick on the TX is for collective pitch/rudder control

depends on what mode you fly, In mode 2 (which is the most common for helis) that is correct.

- Leaving the right joystick for cyclic pitch ?

Again in mode 2, thats correct. have a look at attachment for flight modes.

If your starting off, I would say dont worry to much about a govener just yet. learn to setup your throttle and pitch curves correctly. then when/if you advance to 3d you can look into one.
Try find a club and join, memebers can explain alot easier to you while showing you at the same time. Where are you located, they are alot of heli clubs around Ireland and im sure theres one fairly close by.

Forgot attachment :rolleyes:

Great Thanks...well explained..

I'm actually in Budapest with my TX/sim, but my heli is at home in Carlow..
Hope to get it off the groud at xmas
