While I don't have the GST 7.7, I've got the Nemesis, and have had the Genesis too. I have to say that of all the different "non-racing" nitro trucks I've owned, the CEN Genesis/Nemesis is my absolute favorite!

I've owned Savages, Revos, MGTs and I've come back around to owning a CEN. I think they are just great. Fast for their size, durable. Just a great all-around product. I'm thinking of trying one of their Matrix Arenas instead of my ST-R....
