This is my HSP FLYING FISH my 2nd and most recent build, it's pretty much basic chassis I only upgraded the knuckles to Aluminum set as far as the chassis, I installed Rocket Pro V3 motor and Quicrun 120A sensored brushless esc other basics like receiver and servo also installed nothing crazy also did light kit on it with same body like the first got them on a deal, on this one my rear lower suspension arm is broken from going airborne from debrie on the road thank the lord not a bad wreck those upgrade parts are also on the way from Amazon so for the moment I have nothing running but I get great performance when they aren't wrecked, haven't had the opportunity to gps a speed run yet but that will be done as soon as my parts get in and I do repairs I've been super impressed with both my cars I get very good speeds from both but the HSP offers more fine tuning with the sway bar and adjustable links my only complaint is I don't have a big enough area to run them.
