Slash 3S...
I had both my Slash and GTP2e on the track this weekend. The Slash on 2S was rairly comparable to the GPT2e on 3S. If you can keep the Slash cool 3S is incredible. Our track is MUCH smaller than the one at Corona and I end up on the brakes too much and heat is an issue.
I'm anxious to see the conversion as well.
I'd even love to see a little attention from Traxxas. They have already licensed the mustang make us a big one. On the 1:16 side the have the Revo, Slash, Rally, Mustang, Nascar Truck, and summit all from the same chassis. Just seems like a no brainer.
