Yeah I am currently running the Align 430L with a 13T pinion. The switch to 20C packs from 15 helped, but in stiff breezes the motor bogs frequently when I have to add in pitch to keep the heli out of the dirt. I waited weeks for a dry, still day outside, but I have given up hope. This time of year is breezy, and I don't want to park the heli in storage for a month or 2 waiting for a day with no wind.
