Yes, it is better to get someone to trim it out for you. I just did a maiden on my 4*60(first low wing) and It was all over until I had it trimed. About 2 minutes after it was trimed and flying good, the screws vribrated out of the muffler(forgot to tighten them ) and I had to do a dead-stick. I was surprised at how well the 4* glided...
