If you have the RTR you do not have turnbuckles but one-piece plastic rods. Like on the SS there are 7 turnbuckles I can think of but you can go to HPI web site and look in the SS manual.
You have one that comes off the steering servo, 2 that go from the steering bell to the knuckles, then 2 to set camber on the front C hubs and 2 on the rear up rights to set camber.
