Default RE: Low tail in turn


The original owner provided the plans this weekend.  The plans are for a Sport 40.  He changed the landing gear to Conventional, put a tail wheel on it and 3 half inch pine blocks that moved the engine forward of the designs original location.  I bolted in a SuperTigre .61 ABC in the
motor mount holes that were previously drilled for a ,40 something.

I removed the coat hanger wire that was used for control rods, Tossed away the plumbers nightmare Aileron hinge rod, added 4 servos to the wings for independant Flaps and ailerons.  Also tossed the 6 ounce tank in favor of a 10 ounce slanted tank.  Once the modifications were made, I checked the balance.  It's between 25 and 30% with a full tank.

This past weekend, I added full telemetry to it, and also added two washers beneath the rear mounting lugs to give it more downthrust.

The added downthrust seemed to help immensely.  I also bumped the rudder clevis in a hole on the control horn to get more throw.  These changes seemed to really work well.  There's still a little of "Low Tail" in a turn, but it is marginal compared to what it used to be.


Thanks guys... 

Will post a flight picture as soon as I get one.
