I'm doing the same thing, I picked up a GS storm Pro for $100.00 with servos, and a hyper .21, which seems to have an air leak somewhere. The parts on the Pro seem really well built, much better than the kyosho parts, and right on par with the Mugen's, and everything is SO MUCH CHEAPER!!!

two weeks later I now have a new rex 421b, and a OS RG for back up. All i am going to spend money on is engines now.

I'm going to test the idea that its all about driving and car set up. I feel for the guys with their X-rays and prospecs and SP2s when they get abused by a three year old storm Pro, LOL...

before I got out, I had a mugen mbx 5 prospec, and a kyosho 7.5, both of which seemed to have the ability to have a good bit more travel than the storm, is there any way to increase the travel without cutting too much A-arm out?

Also, does anyone know if GS has a shock for the storm with 3.5mm shafts? I replaced the front shocks with mugens since one was bent.
