well!! mine is ready to fly it's not a redwing but a goldwing kit same plane from what i hear???? dle 55 with a pitts muffler and i had to make the modification to the lower firewall for clearance, the smoke tank is installed in the cannister tunnel, and it all works!!! running 2 life2100 for the flight 1 2100 for the smoke pump, and a 2300 for the ignition, all 7955 servo's for overkill and smart-fly dual reg w/failsafe switch because i had one already (used it for the battery back up) the sullivan smoke pump is pretty kool you can program it in sync with the throttle!!!
haven't gotten a auw on it yet will do it when i go to the field. i set the c.g. at 5 1/3 inches from the leading edge and still had to add 9 oz. of lead in the nose???
