Hi all. New to the forum but have been enjoying ksp & the realism overhaul for a while now. Really enjoying it. I have just about completed all unmanned science tasks around the Moon and have a few questions please: 1)The 'superstretchy' fuel tanks, do these unlock in the tech tree? I have 5m maximum. So I have a lot of engines that are way too big for the biggest fuel tanks I have. I am on about tech level 4 or 5 in rocketry. 2)Same with the Stretchy SRB's, these are locked at 1.25m or there abouts at the moment, I am on level 2, does the width adjuster get unlocked with the tree also? 3)What is a good re-entry profile for the mk1 lander? I managed to get my probes back by aero braking and periapsis of around 65km from the moon, they just about made it! But seems a bit harsh for manned pods. 4)The only downside I have is the terrain on Mun and Kerbin is all very flat and boring, also some clipping issues with lander feet on moon, is that the part (AIES legs) or the terrain due to rescaling? Is there a way to use the whole package, (DRE,FAR,Realfuels, etc) with stock planets and still retain the challenge level? Purely for interesting landscapes again! I am really enjoying the realism overhaul and this career mode. I have done a lot of modding for other games so I know the work that goes in. I have already made myself a new navball, but I am enjoying plying too much to start modding, yet! Thanks for all your hard work! duckhunt
