i just tried my kyosho 7.5 body on my hyper 7 and it works , the mounting holes are a little off but if its new and you drill them it will work. almost a perfect fit.
www.razorgrafix.com has some 7.5 bods for $8 clear. also he can beat any ones price on a paint job or he will match it. talk to BLADE and tell him Z-MAN sent you he will treat you right.
