Never flown a nexstar but all the instructors said i picked god (alpha 40) and added that the nexstar flys sooo poorly that it was amazing. They say it is heavy for its sizzed and that according to them it is way off cg whilie the facotry says itws ok to fly liek that most here fly with 2 oz of spinner wight the rx pck under the fuel tank and about another 1 oz glued to the firewall at this point the instrocors say it flies nice and it doesnt drop the tial in a turn but unfortunitly this adds to the wight which was a problem to start with...
