XB-70A

Excellent achievement ! I'm gonna ride it listening to :

Thank you to all. Sorry for the delay I remain absent these days and did not have time to answer. By following the tutorial of capi3101 I've realized that I had taken a lot of capcha without realizing it (probablywhen trying all the buttons at a time), and the first prototype was there. Here it is: A true crossbreed... @TheXRuler : my sole VTOL project actually was a Ryan XV-5 like (waiting for a XV-4 like project instead), using in-wings lift fans, so it requires an air density near the "Kerbin standard atmosphere". But as you recommended I think to turn this project to Laythe and leave Duna to the pure rocket-landers design. I switch this topic as "answered", all your tips will greatly help me (when I have enough time to applied them). Thanks again.

It's actually a scalled down model, with a 38t max weight. And as you wrote it Kuzzter, this is no more than a challenge to force me the realization and operation of this prototype, so HyperEdit isn't an option. May it will be an idea as "good" as the doktor Porsche use its Tiger P chassis at all costs, perhaps it will be a success as the Skyraider concept. I take note of all your suggestions to change the design accordingly in case of multiple failures.

Thank you all for your advices. There are so many things that I don't know which to begin (!) As he was advised to me, both J-X4 are gone, their drag was too important, without considering the jet fuel mass that had to be embedded (and be a dead weight for the rest of the flight). I managed some minutes ago to launch, orbit the Mun and recover one experimental ship without any losses (pieces as crew members). The trouble is I do not know the procedure for taking screenies. This project is made of a small pack of pieces from around 50 mods, it got a Mk3 cockpit a V-tail, two canards plans, trapezoidal low aspect ratio wings and the main landing gear is partly housed in the four segment Mk3 cargo bay. Of course this would not be possible without a bit of "cheating"... propulsion is provided thanks to the Impossible Innovations mod from jandcando (http://forum.kerbalspaceprogram.com/threads/86331-0-24-x-Impossible-Innovations-0-5) with two LE Deuterium engines at the wingtip to reach a 210 km Kerbin orbit. Each coupled to one x8 deuterium tank they still have some once above the planet. Two other HE Deuterium engines are installed near the trailing edge of the wings, each with a x2 tank. They provide enough thrust to take-off from the low lunar gravity. I have not yet designed a simple exploration vehicle, and have therefore loaded two tons of batteries to simulate its weight. To be honest this stupid idea originaly came from Ace Combat 5 the Unsung War nostalgia, where we had to defend a mass driver launching site with a lifting body SSTO carrying two SRBs.

Hi everyone, First of all please forgive me if I made an error to wrote this thread in this section... Now here comes the problem. I would like to launch some kind of 'Duna express' flight since two days but every test ended by a complete or (at best) half-failure. Here are the goals that I have to meet : - Standard take-off and landing, no vertical launch (from Kerbal and Duna) - Max crew of 4 - MTOW 80 tons - One or two turbojets as a gliding assistance when descending back to the KSP - Payload consisting of a Duna 'jeep' with a 3 tons loaded weight - No in-space rendez-vous for refueling - Nothing should remain on Duna, each parts and crew member must return on Kerbin I firstly choose to use a Mk 3 large cargo bay to place the jeep but my first problem was to 'deliver' it on duna, I chose to reverse the section like a bomb bay and drop the vehicle from here once on Duna ground but without any crane but how to raise and re-hang it on board. Then I found this excellent add (http://forum.kerbalspaceprogram.com/threads/79542-90-SXT-Lack-s-Stock-Extension-SXT-19-07DEC14-KSC-v3?p=1640505&viewfull=1#post1640505) giving a classic loading ramp. Now here are the problems : lift is insufficient in most of the configurations I tested, controls response is terrible (not that it is bad but over reactive), probably due to great instability. The installation of the J-X4 in lateral nacelles causes high drag while an in-tail dual installation dangerously back the center of gravity, inscreasing the instabillity. And finally the most frustrating, I do not manage to reach the upper layers of the atmosphere ... the speed is still insufficient and thrust with different liquid engines as on-wings solid boosters configuration near always too low to compensate the mass. Does anyone of you have any ideas or concepts that could meet these requirements? Thank you in advance.

Thank you for your answers and explanations Trinzilla and CaptRobau. I thought at first take care of this in "manual" to make some experiments, my only experiences were simple modding of FS9 and SFPs cfg long ago. But the shortcut offered by the "Cloud configurations for Outer Planets Mod" is tempting. I'll try it but probably will return to the original Urlum given that its satellites remain at 90 degrees on its axis.

Thanks for your welcome everyone. I got a question about Urlum, could there be a way to change its axis of rotation by 90 degrees or simply put its rings to a fictitious north-south axis by CFG edits, making it appears as Uranus ?

This may sound stupid, but after a long time I finally registered today to thank the team responsible for this fantastic mod. Really what an awesome work!
