I normally solo Rajang with GS though whether I kill it of not depends on the "will of the Rajang" (That quote should be a thing Palkinator XD) When he gets to area 3 (Primal forest) I try to mount him when he's not in armor mode or at least trip him up. But for the horns, I really don't know how I do it with GS (lucky hits on the most dangerous place to be near a Rajang?) but if I break one and he limps I just let him sleep then give him a lv 3 charge to the face and it usually breaks the other horn and kills him... but that's my strategy for HR Rajang cus my gear and guild permit isn't high enough for G rank Rajang.

Maybe a Sleep weapon would help especially if its a Sleep GS but idk what weapon you main, so yeah that's my not-really helpful suggestion, but it kinda helps :p
