HelicopterMain Discussion › DX8 trim setup??

I was just going though my DX8 creating a new model setup for the X5, and in the system setup menu I found something called "Trim Setup." In here, you can adjust the trim for the following functions: Thr, Ail, Ele, Rud, R Trim, L Trim. Interestingly, the trim on ALL these functions is set to 5. On the bottom right hand corner it says "Type", which can be changed between "common" and "F mode."

Can somebody explain what this is, and why all trims are preset to 5?? Should I change them to 0?

I am not able to look at my DX8 at the moment. I am not sure what the modes are but i believe the number is steps per click of the trim adjustment when you are centering servos etc. You can set it lower and it will make smaller adjustments for better centering of servos and such.

Is that all it is? And why is it all set to 5? I don't remember doing this.

offgrid got it - the default is 5. you can make each step of the trim more coarse with bigger numbers (i.e. each trim click = more) or finer. If you set them to 0 then clicking trim adjustments won't do anything. some like to do this to prevent accidental trim adjustments from messing up their gyros. some like coarser/faster adjustments on throttle trim.

The number is the number of "clicks" (steps) of trim each servo will move when you bump its trim tab on the transmitter. You can set it so that each time you hit a trim tab, the associated servo will move a little, or a lot.

The number you see is the default value.

Setting a value to zero disables trim for that function. Since the trim in each flight mode for a heading hold gyro should always be the same, setting the rudder value to zero insures that you don't accidentally have different trim values. Some FBL controllers don't want trim to be moved after the controller has been set up and programmed. In that case, you'd set the trim step to 0 for pitch, aileron, and elevator.

F. Mode allows the trim in EACH flight mode to be separate, COMMON makes trim in all flight modes the same.

Page 16 of your transmitter manual is your friend.
