Hey guys i noticed in some of the pic on rc50 from the icc in vegas Pauly L. and Josh Cyruls 1/12 cars they had lrp mounted with reciever packs.. Paul you could def tell he was running a SSx SS with a fan mounted on the chassis anda reciver pack.. Now joshs you cant tell what lrp speedo it is but he also has a fan mountto the chassis and a reciever pack.. i thought you could not use packs or werent suppose to? Is there a way to or gain from it?
