Cyclic Direction and Tail Direction instructions

[aamacgregor]

For the cyclic direction instructions the VX1 Setup Guide states:

Operate the cyclic stick and select the option that makes the swashplate move the correct way.

So on my Gaui X5, if I wiggle the right cyclic stick, aileron moves in the wrong direction, but, if I lift the helicopter and wiggle the helicopter back and forth the VX1 attempts to compensate correctly (i.e. the swash plate opposes the direction of travel in an attempt to keep the swash plate level and does a pretty good job). If I follow the above instructions and correct the swash plate control movement through the VX1 instead of the transmitter, then, if I wiggle the right cyclic stick, then the swash plate moves in the right direction, but, if I wiggle the helicopter then the VX1 attempts to compensate incorrectly (i.e. the swash plate moves in the direction I rotate the helicopter, rather than opposing the moment).

The only way that I get get the correct behaviour, is to correct the swash plate control movement from the transmitter and put the VX1 cyclic direction back to its original value - that way, if I wiggle the cyclic stick, the swash plate moves in the correct direction, and if I wiggle the helicopter the VX1 attempts to compensate correctly. Is the manual wrong, or am I missing something?

I have the same problem with the tail. The VX1 Setup Guide states:

Operate the rudder stick and check if the tail rotor pitch moves the correct way. Reverse this parameter as needed

But if I do that then if I turn the helicopter left, then the pitch change on the tail blades does not attempt oppose the movement, but instead puts the pitch in the same direction as the left movement. The only way to get the correct behaviour, is to reverse the rudder in the transmitter, and put the VX1 Tail Direction back to the original setting. Again, is the manual wrong, or am I missing something?

Thanks,

Have you seen Bob O's setup vids for the Vortex ? Bob O - YouTube

Yes, they say the same thing as the manual, but the result is the wrong behaviour.

I can only guess that maybe you've got your sensor setup wrong? ie. this bit..

Try PM'ing Angelos. Worth getting right ..

I had this but otherway round,cyclics worked right,gyro comp didn't...will look for the post for you,it may help.

Just read again and it's not that helpful.IIRC i had messed up part of the swash setup,try and redo the swash settings in the correct order.

Either Setup::Transmitter is wrong or Setup::Sensor. See also here: Spartan RC

Thanks everyone for your input. What I would like to say is, the instructions are absolutely correct... I just can't read properly... on the plus side, my analysis of how to fix the problem was correct... but was mentioned in the transmitter section of the instructions.

Angelos, you are right, the problem is that I'd somehow managed to miss step 3 in the transmitter setup. i.e.

Move the sticks and confirm that aileron, elevator, rudder, collective and throttle* operate in the correct direction. Reverse any transmitter channels that move the wrong way.

I was sure that I'd been through it all, but clearly not since aileron and rudder were reversed when the transmitter was on default settings. Reversing them made everything move in the right way on the datapod transmitter section and leaving the VX1 on the default settings for cyclic direction and tail direction means that it now all behaves as expected.

As a double check I think I'll go through the whole setup procedure again just to make sure that I haven't missed anything else - I'm kind of worried that I managed to miss such an important step and it's got me wondering what else I might have missed! I think it's all the excitement of getting it up and running that is distracting me!

I really like the setup through the datapod by the way. It makes everything so easy! I was also pretty impressed that the VX1 got the +12/-12 degrees spot on and I didn't need to make any adjustment!

Angelos, I thought I'd ask one question about the tail setup. My endpoints are set a +100/-100 respectively and are pretty close to the full extent in either direction, so I'm happy with that. The thing that concerns me is that I had to set the tail trim to -80 in order to get the 90 degrees and that seems quite a lot to me... could it cause me any problems?

Thanks once again,

Andrew

No it wont cause problems but if you are picky you can rotate the horn to another arm which may have a slightly different offset and require less trim. It works with Futaba and few other servo brands.

Thanks, in that case, I'll leave it as it is. I'm really looking forward to flying the X5 with the Vortex
