RE: Graupner Zlin Z-50LX ARF
Hi there. I never finished mine. I have a Hacker B20 18L 4:1 also, but I never installed it. It went into a Wattage Super Impress. I will get around to it before summertime. I just have too many gas and elect. projects and some just don't get into the air as fast. If you get yours airborne, please update me on how it flies. Thanks, Kurt.
