Powered mine with a BME 44 cc. Took 1 1/2 lb nose weight to balance because elevator servos in tail. Use stock pull-pull setup to avoid this! Replaced retracts with good 1/5 scale Spring- Airs and Robart Struts. Plane flys excellent at recommended cg. In third flying season with 100+ flights. Will compete in Sportsman class at Texas Scale Masters end of May 2005. Bomb does drop! See photos in my gallery. This plane will balance perfectly with G45 or Fuji 50. Paul
