So...

The servo is an AS3103PG continuous servo. The board is an IBU2 Pro. I plug the servo to the board and power up. The servo starts moving, very very slowly on one direction. Why does this happen? Shouldn't it only move when I want it to? How do I solve this?

You need to trim the channel it's on till it stops I'm afraid. I have this issue with the 360 servos on my boat

How do I do that?

Adjust the trim on the channel it's on on the transmitter. What are you using it for? If it's for turret rotation that seems strange and might be worth talking to Ian.

Ah, the slider thingy below the turret stick (left side of transmitter). I've slid it this and that yesterday, but the servo still creeps along counterclockwise regardless of trim's position. It is for turret traverse as I replaced the HL traverse gearbox for servo.

Yeah, I'll be emailing Ian soon since I have more problems with the IBU2 Pro ever since I used a LiPo (2s 7000mAH) yesterday (the tank thinks it is Opposite Day, i.e. it goes left when I want it to go right, backwards instead of forward, etc and it runs immediately when the engine starts without any forward or reverse stick movement).

Sounds like you've got your motor plugs backward, and not calibrated the ibu...

The motor plugs were right way connected but ran backwards hehehe so had to reverse connection to make it run forwards.

When I received the IBU2 Pro and tested it initially, everything was running fine and proper. For some reason it doesn't do that now.

I'll let Ian know soon so he can help me fix it.

Tnx tomhugill!

You can also reverse the direction on the transmitter.

What radio do you have ? I know that on my Turnigy 9XR when I get a servo creep, I have to set the offset to the opposite to get rid of it when the trim doesn't work. Offset in Turniogy basically determines your default position setting.
