My PT-17 Stearman had her maiden flight atmy club's BBQ yesterday. All went well for the most part. Got alot of compliments from the guys on how nice she looked. The only problem I'm having is she wants to climb, even at 1/4 throttle. I did balance it as per the manual, and it's actually a little nose heavy! I had to give it alot of down trim to level it out. Any ideas?</p>
