Please try my only-stock-parts moon rocket design.(attachment) It handles not too bad and has plenty of spare fuel if your flying is not so perfect. Manual/Checklist: - Turn on SAS - set throttle to full - Start first stage - Dont touch anything until you have an airspeed of more than 140 m/s - At 140+ SLIGHTLY and CAREFULLY point the rocket in the right direction (90 degrees). Do so by disabling SAS for a few seconds at a time. - After the first stage is burnt out and disposed of, the handling gets 'wobbly' but controllable. Point it into Orbit now and use the fuel of the second stage to expand the orbit as far as possible. - After the second stage is burnt out you should have an orbit that intersects with the mun orbit. Use the third stage to alter that and initiate approach to mun. - If you did perfect maneuvering, you have enough fuel left in the third stage to land with it. If not, you should use the 4th stage. If you have a significantly better design (stock parts only), please share.
