I'm working on improving my Tiger 60 ARF's performance for Sportsman Pattern use...

The main problems I am seeing:

1) it loves to roll when you kick the rudder trying to do the stall turn. Its very hard yto get through the stall turn without ending up 90 deg out. Experimenting with technique of making it pivot witout rolling are getting me nowhere... (best result has been with a crosswind and being able to do the up line with the plane canted 20 deg to compensate)

2) It noses up with power... or drops the nose when inverted. I've got the CG at 5.25 inches from the leading edge now... (thats 43% MAC) The plane is stable... but on the edge of getting touchy to elevator trim (I don't think I can go any further back)

The trike landing gear helps a lot in getting good take-off and landing scores. I've got a piece of fuel tube on each side of the nosewheel and pressed in HARD when installing the 2nd wheel collar... the drag on the noswehll makes it easy to have the plane sit in place on the runway at idle. (if it doesn't that's a downgrade on the takeoff)
