jsixpack1......I too have a nexstar. Took several fixes to the plane to get it to take off properly. I'm sure these guys know alot more than I do ...... as I am still a newbie at this sport. What fixed my take-off problems was FIRST.....make sure the front wheel is
EXACTLY lined up with the rudder. I had to grind the shaft a couple of times to get this to STAY WHERE I SET IT.........NEXT........
(and I think this really helped) I changed the wheels to a harder rubber wheel and increased the size to 3 1/2" wheels. I think the tire size change also made my landings smoother once on the ground.

I know this is basic stuff and Britbat seems to know alot about this bird.....so not taking anything away from what he says......I'm sure he
knows what he is talking about for sure....just sometimes I tend to overlook the obvious and make it some things harder than they really
are.

Just a thought here.....
