Here are a few of my DLE 20 powered Pica FW 190 D9. Perfect combo. Tons of power for this plane. Been flying it now for 3 seasons with this engine. Only had to touch the needles a couple of times during this period. Rear intake needles are easy to get to, with a small access hole in fuselage. I have a long screwdriver for this, and I paint the heads of the screws white, to cast light on them in a dark place. Works very well.
