i picked up an avistar at a garage sale a few years back , it was the stock hobbico RTF , it had the OS .40LA in it , it flew good with that , then after a few flights i wanted something a little more , i had an Italian Super Tigre .45 laying around so i put it in , WOW , what a difference it made , it was my favorite plane to fly , then it met its end sadly...... Ive since switched over to electric , and found an original Hobbistar 60 ARF that was almost 20 years old NIB , put a .46 equivalent outrunner in it running a 5 cell lipo , flies just like the avistar only bigger , its a good plane and you did a Wonderful job with the rebuild and covering. my dad was always critical of his covering jobs but to all of us that look at it , all we see is a beautiful airplane! good job and id like to see your other build as your doing them!
