My newest plane that I am putting together slowly but surely.
It is my first gasser that will be powered with a DLE 20 RA.
The manual that is supplied is pretty much useless so I started a thread on another forum where others that bought the plane can help each other to get it done.
Most have reported that the plane is tail heavy at final assembly and needed to add anywhere from 16.5 to 14 oz up front.
This is due to the plane having two elevator servos installed at the tail.
One member who is following the thread and thinking of purchasing the plane has added a post of one of his planes with the same issue.
He removed the two ele servos from the tail and installed one servo on a tray just behind the pull pull servo tray. The servo is mounted on its side with 2 ball links on the servo arm. Each ball link is attached to the same hole on the servo arm,one on the right of the arm and one on the left. He used 2 carbon fiber pushrods to the one servo.
By doing this he got rid of one servo and the 14oz of weight up front needed to balance the plane.
I'm waiting on the arrival of my motor to see how mine balances out.
The cog of this plane needs to be at 4.5 inches, verified by another TBM SBACH owner. He said the plane flies very nice after all the work.
TBM has been no help.
Update to come after I install my motor.
Motor installed and sure enough the plane was tail heavy.
I ended up making my own battery pack out of 2 3500mah 3.7v li ion/lm
