tail problem

[sas]

hi dose any one know why my mini pred tail will only go one way or a littel to the other if i slide the trim right to the end. iv tried sliding the servo up and down and all so tried othere servos but nothing i do makes it any better if i set the gyro to rev then it works the othere way i think a long the line i have set it wrong on the tx to the sevo or gyro ..

Sounds like its not set up correctly, when you connect battery it maybe that you have to wait few seconds for heli to set or once set does tail slider sit centre of shaft if not then would need to set it back up again more so after say a crash.

iv waited for the gyro to set and tried moving it back to the center but no look it will still only go one way..

Does the gyro have a plug with single lead inti receiver

Mate,

I've got a fair bit of mini pred experience (I was flying mine at lunch time) but I'm not entirely sure what your problem is. Are you saying that you've got limited rudder response in one direction? If so, consider increasing the potential throw of the servo by putting the push rod further out on the servo horn.

If you're saying that the tail is drifting then consider adjusting the gain up a bit with a small screwdriver on the gyro itself. Finally, check that you are using heading hold mode on the tx.

Are you using the stock Art-Tech tx?

Happy to help, but I'll need a clearer indication of the problems first.

it has 1 plug to it that say,s servo out and 1 to the receiver

Then you just need to check that tail trim on radio set reset to centre connect heli & check that tail slider is centre of shaft if no just move servo until. Give that a go.

when i push the stick to the right it will go all the way when i push to the left it will only go a small amont. it is the stock one that came with the heli

[sas]

i set all trims center and set center on shaft but it will still only move a small amont to the right

Can only think that something in the radio is not right just check if 'travel adjust' is where the problem maybe.

not quite shore what you mean by check if 'travel adjust' is where the problem maybe.

could it be that the servo is too far along the boom and all of the centering is just making this worse.

Plug the servo directly into the receiver, bypassing the gyro altogether, with the trims centered and then make sure that the horn is at 90 degrees and moving an equal distance each way when you move the stick.

Once this is done, if needed, move the servo along the boom, keeping the servo arm at 90 degrees until the tail pitch slider is in the middle of it's travel which will at least give you a decent starting point, now return any settings on the gyro back to the factory settings and reconnect it. See how that goes...

Also check that everything is as it ought to be, pushrod length and make sure that nothing is sticking or bent in the mechanics.

By taking the gyro out of the equation, you'll be able to make sure that the servo is ok and that the gyro is set back to the starting settings as specified in the manual and that nothing is bent or sticking.

Good luck...

sines doing what you said it now moves the same amonte in both directions but not all the way to each side

[sas]

it did work moving an equal distance each way when i move the stick.
when i pluged it in to the receiver.how do i reset the gyro to the factory settings.
