REFLECTOR: Roll trim?

[Douglas Holub]

That's the roll trim that came with my kit, too.  I also am not using it.  I mounted my Trio wing leveler box back there and use it for roll trim.

  I've never had a (working) roll trim system... 

  Mine is the original STD-RG.  I purchased the kit from Danny himself, so this really is the original-original.  Back then, there was an electric motor mounted on the aluminum bracket which supported the aileron cable connection to the control stick torque tube.  The motor used a string (yes, just a string) which was to be wound around the motor shaft and whose ends were connected to springs, which in turn were connected to the control stick torque tube.  In theory, the motor put force on the string, which in turn pulled the springs, which in turn applied force to the torque tube.  Rube Goldberg, anyone?  In practice, the whole thing never worked worth a damn, so I got rid of it.  1100+ hours and counting... 

  My best advice - just build it as straight as you can.

  I'm finally getting around to trying different springs to go with the cog belt and pulley trim system (thanks Geoff!). 

  And while sitting back there looking at the whole roll trim thing it occurred to me that none of the single engine piston planes I've flown have a roll trim system. If the plane flies with a heavy wing, that's fixed by rigging. Either adjusting the wings themselves or adjusting the ailerons. 

  So here's "The question":  Has anyone omitted the roll trim mechanism?
