    Last weekend we welcomed our new dual seat high performance glider, Sierra Hotel, to our club. It's a Duo Discus XLT with some nice options. Isn't this aircraft just sheer beauty? A feature new to me are the 'flaps' which are extended when pulling the speed brakes. So these are...

    Challenge Earth → Moon → Earth in less than 24 hours using default XR-2

    You can save a bit of fuel by activating the airspeed hold autopilot right after take-off. It will then throttle down a bit. Then turn towards your launch heading and disengage the autopilot and throttle up to the max. Or leave the ap on. When you pitch up further, it will also throttle up to...

    Did you have any Orbiter experience prior to august? Seems like you're picking it up really fast. Good job!

    Our new flagship under construction at Schempp-Hirth Flugzeugbau in Germany. We did choose for the proven concept of a combustion engine (which folds out of the fuselage). We may sell it in the future when FES (Front Electric Sustainer) become available for this type...

    Flight Question [**SOLVED**] DeltaGlider Scramjets

    I think the scram doors are exclusive to the DG-XR1. You can see the button in the screenshot. If you haven't done so, I suggest you download this add-on for practicing. Scram engines only work in a certain range of dynamic pressure. They won't do anything if your airspeed is zero before...

    Yup, confirmed. PursuitMFD plays nicely now. Well done!

    Docking two XR5's in the same way results in this (the ship in the foreground is oriented prograde) Can you compare the port orientation of the Starship/Tanker with the one in the XR5?

    Using the XR5, PursuitMFD can do the docking. The Tanker is in Prograde orientation. The nose is pointing backwards as well compared to the first screenshot in the previous post. But unlike Tanker_2, the XR5 is pointing the top towards Tanker_1. Not sure what that could mean though. I'll try...

    Ok. I'll do some experiments as well. I think the XR5 presents the same situation. I'll check how PursuitMFD deals with that.

    The source tank selection works good btw. Thanks for that.

    PursuitMFD can handle attitude. But the problem is, PursuitMFD will bring pitch, yaw and roll to 0. But that doesn't give the desired orientation. This is what happens then: PursuitMFD is in docking relative mode and pitch, yaw and roll are zero'd. (Also, rZ=29.09 seems offset by 10 because pZ...

    Allrighty. In a single take: Launching two Tankers twelve seconds apart. Catching both boosters. Tanker_1 goes into an 200x220km orbit, Tanker_2 into 200x202km and therefore catches up. Then aligning Tanker_2 with a small anti-normal plane change at the ascending node shortly after both ships...

    Thanks! I'll record a video of how I am using Pursuit MFD atm.

    It would be practical if you could select a 'From' tank, being either the main-, reserve- or payload fuel tank. That would allow for a scenario where the Starship only has do dock once.

    Ok. I was able to transfer fuel into the main tank now. And also from Tanker_1 payload fuel into Tanker_2 payload fuel and from there back to Tanker_1 main fuel. I see now the the max payload fuel is 170000. Then there's no issue I think with that.

    Hi Brian, I think the idea of SpaceX is to launch multiple tankers first and have one of them serve as the main fuel depot. Then the crewed Starship is launched last and docks only once with the deposit tanker. Therefore, I've been trying to dock two Tankers. Docking is very hard now. When...

    Ok, I'll keep between 2.5 and 6T before the reentry and activate the reserve fuel when it goes into skydive mode. That works. I have a problem with docking now with the new docking ports. I used Pursuit MFD before, but now the ship has to pitch 180 degrees. I haven't been able to figure out how...

    Hi Brian, After a few months I am getting back into flying the Starship. My first landing attempt was succesful. But I ran out of fuel just meters before catching. The arms did slide down fast and it caught the ship anyways barely above ground level. Close call.. Question: At what moment...

    Hi Brian, Meanwhile, I've done many more reentries aiming for the tower at BocaChica and I don't have any issues anymore. I am mostly using BaseSyncMFD assisted with BurnTimeMFD now. That seems to work all of the time. So the reentry AP works great! I don't think it needs any improvements at...
