Hi guys, I must say, for the first time I got stuck in KSP. BUild this rocket in carrer mode, hope to fly to Duna and back - dV ~ 12 000 m/s, but rockets keep desintegrating shortly before or shortly after launch. Can't figure what did I wrong. Could you tackle this problem. Youo can download a part file from here: http://rapidshare.com/share/1EEE82789553CFFCEB2C53394512BF63 many thanks vtgbart
