I believe he is a nitro guy. He hasnt replied to his pm's on the traxxas forum. I got ahold of him with his paypal adress. He is a machinest and has made quit a few items for the traxxas vehicles. Dude could make a killing over here making custom stuff for people.
Not sure about oomp, I have invited him a number of places that he actually signed up for but it seems he keeps on going back to the traxxas site? he's a kick ass dude and his idea's are killer, im using his part to lock the revo trans into second gear:)
