Greetings everyone! Going to present You my universal Ion Wing MK IV - SSTO Categories applying for: - Best light cargo spaceplane - Best all stock parts spaceplane Mod's required: None, but I'd suggest You to use Mechjeb2 & TimeControl for this. Crew Capacity: 1 It's a fully capable SSTO-Aircraft giving you the possibility to visit every Planet/Moon and land/take off from every Planet except Eve / Tylo. (TWR too low) It's Aerodynamics are well designed, making it easy to ascent from Kerbin in no time, landing on Laythe / Duna and return. Link to Craftfile: http://uploaded.net/file/wv8hn8kj Going into Details now: - Several High-Res Screenshots http://imgur.com/a/ymHGF#0- Starting Mass is 5,743t cotaining maximum Jetfuel & Xeon Gas - Cost: 121183 - Max possible d/V for traveling is 11631 if You decouple the Jet engine & 2 Wings @ Orbit (Just launch Stage 1 for that -WARNING: Jet Engine is neccessary to take off from Laythe!) - Part Count: 198 - Battery Capacity (attached to the bottom) is around 10,7k giving You around 3minutes20 acceleration without any Solarpower - 1 Jet Engine, 5 Ion Engines is a devastating combination for both atmospheric & non atmospheric planets/moons - Additional Science Modules can easily be attached to the front without sacrificing any Aerodynamic abilities. If you wish to visit Laythe, keep your Jetfuel at maximum (90), approx. 35-55 is needed to get into Orbit from Kerbin depending on Your skills. Every other Planet/Moon can be visited and landed with Ion engines only! So just hit Stage 1 to decouple the Jet engine & 2 Wings, giving You additional d/V (11,6k instead of 8~) when You reach Orbit and fire the Ion Engines. Aerodynamics are still 100% fuctioning to glide and easily land on Kerbin / Laythe, although You won't be able to get into Orbit anymore. My suggestion for any trip is using Time Control when you accelerate with the Ion engines, landing can easily be done (even with TWR 1<) when You carefully descent (Orbit Info & Surface Info from Mechjeb2 work wonders here) 3 or 4 Planets/Moons are 1< TWR at full Xeon Gas, you probably have to calculate before you descent. (Or use Mechjeb2) Hotkeys: 1. Toggle Jet Engine 2. Toggle Ion Engines 3. Brakes 4. Raise/Lower Gear 5. Toggle left/right Intakes (some +d/V although not much when used right) How-to Start: Just hit SAS, toggle the Jet Engine, full throttle and aim straight up vertically when you reach 25+ m/s - At 12-14k height, start aiming horizontally slowly and keep Your Vertical ascent at 100 m/s for high fuel efficency - If you closed the 2 sideintakes at the start, hit 5 now and open them for additional Oxygen - try to achieve at least 2200-2300 m/s Orbital before you turn off the Jet engine - Check Your Apoapsis, it should be around 120-130k~ when you turn off the Jet Engine, fire your Ions and keep a small constant acceleration to keep your Apoapsis at desired 100k (less or more Your choice)
