It appears that the weight of HOTOL (250t) is less then that of MAKS (275t) according to encyclopedia astronautica. But HOTOL is longer (44m to 39m) and wider (10m to 6.38m). MAKS had a not extraordinary T/W of 1.4, so my guess is that the 250t weight of HOTOL is too low, since the thrust is higher and so is its size.
