Hi!
You cannot fly a plane with just 2% of travel...!!!
Remember to have a good flying plane it's vital that you first mechanicly trim the plane...not do the trimming with your transmitter.

Then set the transmitter up so you have 100% travel or more on all channels! That's the second most important step to follow.

No to trimmuing!
To mechanicly trim a plane you have to remember that the servoarms must be aligned 90 degrees with the push rods to equal travel in both directions.
Secondly! To avoid flimsy flying surfaces (that can develope into flutter) you allways have to use as short servoarms as possible and to use as long rudder/elevator arms as possible! That's the general rule for all airplanes!

Then you fly the plane!

If you arnt't satiesfied with how the plane behaves after the first flight,conntact a friend ho does know how to set it up for you.
Many times the Cof G has to be changed and also the servo travel in the transmitter, but remember never ever trim it out with the transmitter the first thing you do!!!!
