If you look up the specs on just the ESC by itself it does say 7.5lbs but if you look up the specific combos for specific types of kits that number fluctuates a lot. I listed 6.5 lbs because thats what Castle says about the SCT combos.
MTs and Truggies are my 2 favorite flavors of RC but I like MTs that are more set up for handling like the Losi LST platform or REVO. Those are a little more like truggies though. I still love regular MTs too though like the Savage or MGT etc. :)
