Well, I got my sabres working a-ok on 0.23 by updating the mod with the new DLLs from Firespitter and ExsurgentEngineering. FAR installed as well for good measure. Been having some minor problems with gear stability, but I can't say if this is new or not. I got the gear working alright for Spaceplane Charlie (and don't ask what happened to spaceplanes Alpha and Bravo - it's a sensitive subject and Jeb doesn't want to talk about it...) I've seen a lot of talk about overheating while supersonic, but I keep going past 1700 m/s in the upper atmo without the engines ever going into the red. I guess people should just use precoolers like I do? I guess it's not the most impressive plane showcased in this thread, but it'll get a 16 meter long load of 40 tons into a 100k orbit real quick due to the over-abundance of engine power... While I'm sure I could modify it to carry a double orange tank payload, I don't see a big need for launching two tanks at once, and more importantly - it'd slow down the trip to orbit significantly, and I like things quick and painless; if it takes more than 5 minutes to reach orbit, I'd rather use a rocket. Fully loaded it weighs in at 130 tons. Dry mass is 60 tons. I rather like the design: regardless of fuel level or payload size, the center of mass stays virtually unchanged, since I got the fuel outriggers, the central HL cargo hull, and the engine pods all smack in the middle of the center of mass. Also, it looks deliciously exotic. If it looks like the fuselage is sort of coming apart at the seams... it's because it is. Jeb's flying it empty and pulling 5g to show off for the camera. And no... I didn't just spend all night getting that plane out of the hangar... I wouldn't do such a thing, would I? mac
