Now it makes sense, Squee.
Okay, my mind is set on the MRX-4 with a 1940/8, 6s Evo20 and my 149.18 controller.
Being around the sixties, rcjmaxx, isn't really cool for an onroad machine, but then again, the super nitro is not dialled for hi speed applications like the Evolva or MRX-4. Those two machines with a .21 or a .28 engine made some amazing speeds at the worlds over 100mph. I guess it would be at least at the hi 80s with the 1940 motor.
Its costy, but I'll try to make it my ultimate rc project besides the Phase.2 SuperGorillaMaxx of mine.
Serum, your Serpent is 1/10 scale, right? Those are 1/8 scale, FYI.
