The horizontal stabiliser has two carbon tubes joining the halves through the fuselage. I glued the front tube in place to make the whole stabiliser far more sturdy when ready to fly.
The wheels are 3.5", low bounce with brushed aluminium hubs.
Notice the spark arrestor (left) and arming switch (to its right). Spark arrestors are very effective in eliminating spark-generated pitting in the surface of the Deans connectors.
Notice the gussets added to stiffen the load path from the top of the motor mount through to the sides of the fuselage. Without these the motor could move vertically to an unacceptable degree. Prior to this upgrade the motor vibrated at higher revs!
Notice the servo's mechanical advantage built into the pushrod setup. The outstand of the connection at the elevator is 2.5 to 3 times greater than that at the servo! The same approach is employed at the ailerons. This approach gives the servos great authority, allowing them to hold the control surfaces very firmly and not wobble in the air stream.
This construction indicates a likely range of COG = 177 to 194mm back from the leading edge at the root. These figures straddle the joiner tube as expected.
