I'm almost finished with mine... the construction is good.. I had a couple problems... the major problem was one of the aileron torque rods cracked the aileron... I had to trim the covering repair the cracked wood.. and recover the small section (about 1" by 1")... I think the manual is wrong when giving you measurements to make the elevator pushrod... Mine was a little short... I haven't balanced it yet, or weighed it... but I 'feels' about 5lbs.. maybe 5.5lbs.. I have TS52 for an engine.. Looks good... nice fibreglass cowl, and pants.
