1. The RCS system is effective when used correctly... 2. The RCS system works similar to the SAS module (use the advanced SAS in one stage) and so you need to turn it off to realign the ship. 3. Move all of the RCS fuel tanks into separate stages or it may drain only one tank (BUG). 4. Although G-force does not have an effect at the moment, IT MAY EVENTUALLY KILL! Start practising to keep the Gs off the counter so that you don\'t have to learn when a new version comes out. 5. Sometimes the big rockets aren\'t always best. A long rocket can produce flexing in the centre if you use directional aids so build in scale: If you\'re rocket is long, build outwards somewhat aswell. If you\'re building wide, spread it by adding some length to the rocket.
