pitch setup

[sas]

hi guys a little help again please im trying to set up the pitch on the mini pred but i dont know if i should have the switch in head lock or normal and the throttle all the way down or half way.....

Hi Mate,
first question you asked is for the gyro mate heading lock and normal modes,

before you start ensure the motor is disconnected or throttle hold activated otherwise it bite your fingers,


if you look over at helifreak and down load the videos on how to setup pitch curves for a trex450 is the same principle but different heli

[robgt]

Heading lock makes no difference to your pitch setup - thats gyro...

Put the pitch stick in the middle and set zero degrees mechanically at that point.
Cheers,

Two schools of thought, one is hover at mid-stick and the more popular is hover just above mid-stick, with mid-stick being zero pitch.

Before you play with setting up the pitch, make sure you have disconnected your motor.

Set your stick (throttle) at the mid-point and check the pitch. It should be zero, then check the full and low settings and post them on here

Jason,
Completely true!
I always mechanically setup heli's with zero degrees at mid stick, then use the Tx to adjust to a midstick hover (in pitch curves) if that's what's wanted by the person doing the flying

Just the way I'm used to doing it

Yep - same here Rob, transmitter controlled pitch is where it's at

how do i switch the motor off as it all the wires look soldered on to the motor

[Mike W]

you can get a 4.8 volt battery and plug it in the RX in the heli so not using the lipo ..that way you can mess about with the electronics without starting the motor .. or unscrew the 2 screws on top of the motor and drop it out the airframe ... doing it this way is a little tricky as they not the easiest of motors to put back

Just make sure all your trims are centred and the servo arms are at 90 Degrees at mid stick with a linear pitch curve of 0 50 100%.
Small amounts of subtrim to get the servo arms at 90 are acceptable.

im i being daffed but i dont think im doing this right because i set the throttle to half way set the pitch to 0 and when i take the stick down it says 0 pitch and the same at full

[sas]

why im i getting 0 pitch at low mid and hi stick

[Si Goodchild]

Check the plt dial on the tx and set it to max, note that you'll need to set the adjust switch to on too. The pit dial may need to be adjusted to keep the 0 degrees at mid stick,

is the sevo at the bottom sopost to move when i throttle up

[Si Goodchild]

The one connected to the rod up the middle of the mainshaft which in turn adjusts the collective pitch?

Yes - need to move up as you increase throttle. Hit the reverse switch for channel 6 if it's moving the wrong way.

i think this is going to take some sorting as it would seen that the sevo was in the wrong point on the receiver
