I am interested in purchasing the Team Losi 8ight RTR, I found it on Amain Hobbies for $540, that seems like a good deal, anything to know about it, I do know that the only complaint with it in the reviews was with the diffs being filled with grease instead of oil, what is a good "oil range" to try out

, also, anything prone to breaking on it, like arms... anything to "stock up on"[8D], thanks alot

PS, if there is any cheaper price on a RTR plz tell me[8D]
