MT 03 Trim system

A reforming stirrer!!!!!
I would appreciated knowing how the MT 03 pneumatic trim systrem works as I could nor see a spring BUT that does not mean it was there. The pneumatics get changed from the trim system to the rotor brake system with a tap arrangement.

no there is no spring, or to be precise it uses only an "air spring" an it varies the force increasing air pressure in the upper part of the air piston.
It works quite well (I tested the system on a ELA of which MT03 is a clone)
the nice thing is that inverting flow in the piston you can use it to push the rotor forward when you are taxiing

Thank you Sapientino.:first:

No, not really. IMHO it is to keep the airframe as level as possible against prop torque.
Yes, that's right. The rotor is offset about 1" to the right (looking from the back) to counteracht the torque on the airframe resulting from spinning the prop ccw (also looking from the back).
