All that said can someone break down all the details of all the 17.5 options?? I'm confused on this 17.5 motor line up and hope someone could shead some light. Here is just 2 brands with a few listed.
Express has a "Tornado" D4 17.5
Express has a "Twister" 17.5
Trinity has a D4 17.5
Trinity has a Certified 5% D4 17.5
Trinity has a Maxzilla D4 17.5
Trinity has a Big Blue D4 17.5
Trinity has a Big Blue Certified D4 17.5
Trinity has ROAR Spec D4 17.5
I'm guiessing there are rotor size differences and wire guage thickness differences too?? I'm sure one is better for 1/12 and one better for 1/10 TC ect??
