Nice build, I recognise that canopy from somewhere ;-), I'd suggest raising the TPA a bit and reducing your P values a bit to help with the high throttle oscillations.

This guide will walk you through the process of building a micro long range quad capable of flying 8-30 minutes and more than 4km. The build is moderately difficult, but with the right tools and steady hands..
