It is definately a Hyper7 with PBS...with the spider diffs and the laydown servo I think that makes it either a Pro or a 7.5....so many different versionss over the years...anyways no matter.
Parts should be easy to find as it is a very popular model.
In the UK it is a car that is commonly converted to electric and by all accounts is very good...with plenty of upgrade parts available if you feel the need.
