Gyro set up with Mini Titan

[hydev]

Hi,

I have just finished building my new Mini Titan up and I was looking for some advice on setting the tail up. I am new to R/C Helicopters but I reasonably sensible enough to read and understand the manual so physically I believe the head is set up correct but I'm not sure about the tail.

My local model shop recommended the HG-5000 gyro with HG servo. Does anyone have any tips for me in setting this up? How do I check - without spinning it up - if the tail is going to send it left or right? I assue that if it moves towards the boom it is left and away it's right?

Any help greatly appreciated. Went to 3D masters yesterdays - boy do I have a long ay to go.... :-)

Left stick will cause the pitch slider to go towards the tail hub. Right stick on the TX will cause the pitch slider to go towards the tail casing/boom. So basically its actually opposite to the way you said. To check the gyro direction is correct then give right stick and observe which way the servo arm goes. Next rotate the helicopter nose left and observe the servo arm. It should go the same way as when you gave right stick before. If it doesnt then you need to reverse the gyro. Theres usually a switch on the top of the gyro but it can be diffrent depending on what gyro you have.

Hi,

Right I am getting no where fast - I thought this might happen. I have a Hitec HG-5000 gyro with a Spectrum DX-6i Transmitter and AR-6200 receiver. I have plugged the servo into the cable on the gyro and plugged the gyro gain lead into the aux channel on the receiver.

The mini-Titan manual says I should have a head lock gyro. The gyro manual says the gyro is in headlock mode when the "TL" light is illuminated. However I can only get the "TL" light to illuminate when I set the gyro setting on the transmitter to "INH" (whatever that is the - manual doesn't say). If I'm in the INH mode then I can't set the gain from the transmitter and the red LED is firmly over on LED 8 meaning 100%.

Taking this further if I have it in head lock mode the gyro only moves when the rudder stick is in neutral position and I move the helicopter left then right. If I hold the stick over left and then move left or right it does nothing. So when I'm not in head lock mode the servo only responds to left and right commands. You can do what you like and the servo won't move.

Another point, the manual says I should set the gyro direction but following the instructions this doesn't work. Moving the rudder stick left or right makes no movement on the LED's.

Can anyone help as I am beginning to get very confused!

thank you in advance

First of all your aux 1 channel on the AR6200 RX is for your pitch servo and not the gyro. The gyro gain lead will plug into the Gear channel. Therefore you will use the gear switch to flick from heading hold to normal rate mode. Obviously the other gyro lead will plug into the rudder channel. Me personally i wouldnt use the gyro menu so leave it to INH (means inhibit). Use the ATV's/End Points on the transmitter on the gear channel (channel 5) to adjust your gyro gain. When you flick the gear switch you will see this change from one side to the other in the ATV/End Point menu. One side of the switch will be heading hold (When the LEDs on) and the other side normal rate mode (LED on the gyro is off). Ive never seen that gyro before so cant really comment on the full setup of it but do what ive said above and you'll be further forward. Setup the gyro direction just like i said in the earlier post. Then its just a matter of setting the gyro rudder travel point (usually a pot on the top of the gyro or can be done in a menu if it has an amp or it can be done in a gyro programming sequence). This stops the rudder servo from binding at each side of its travel. So basically you want to hold left and right stick and then adjust the pot so the servo doesnt bind at each end. Or if its done the other way then go through the gyro setup and adjust using the sticks on the TX.
