I've never heard of a virus but the way it sounds its a pretty good knock off of a ofna 7...so prolly alotta parts will interchange...and the 7 seems to be a pretty popular suggestion...I know a couple dudes that have eb-4's and love them...so who knows...if your local lhs is a buncha bang up guys I'd really look at their stuff close..I would learn how to maintain it myself and not let them do all the work cause that could become expensive...but like I said if they are bang up guys they will be happy to show ya the ropes.. Himoto has just been awsome to me and their products are priced great and ive had limited trouble..my closest real lhs is 120 miles one way...so I'd be doing most my shopping online anyways so it works out great...just enjoy your buggy
