No. SH. Like the Mach, Dynamite, Losi, Nosram, Sportwerks, XTM, LRP Spec 3, etc.. mostly RTR engines.
EDIT - I don't think SH is actually the name of the company that produces them, as SH is just a distributor I think. But the producer of all these various 25, 26, 28, and 30 engines is often referred to as SH.
Picco was making the race engines for LRP - the ZR.21X and the ZR.21X Spec 2. But now it's OS... Picco seems dead or something..
