I launched the Cox Shuttle America at Hellfire-22 on an Apogee D10-3. The flight was fantastic. Much higher than a C6-3. However, I paid a price. The heat of the composite motor melted the white fuselage. Perhaps, it was the ejection charge that did the melting, because the parachute compartment is very small. I used a D10-3 once on the Centuri Shuttle and there was no damage. The ebay seller sent me two fuselages, so I can probably make this fly again, but the second fuselage does not have all the fancy decals.
