ISRA MOUNTAIN MOTOR PRO STOCK

So you want to build a MM/PS but are unsure how? I'll try and not confuse you anymore than you might be

This class has been around for about a year. The MM/PS class was developed here at PSD by Chuck and myself as a class that would be highly competitive, only take intermediate skills to build one, fast, and not break the bank to get into.

We're always searching for more speed. I'll pass on any helpful tips as we learn more.

I laid out a helpful "suggested parts list" in the MM/PS proxy sign up thread: www.psychoslots.com/index.cgi?board=general&action=display&thread=796

I'd like to go over that list and let you know about a few cost saving parts that work well and that most of us are currently running. These cost saving parts are highlighted in blue.


All of these parts are readily available through Lucky Bob's

If you already have a Super G Plus chassis then all the better. Note that, to be competitive in this class you'll at least need decent silicone foam tires, Suggested Gears, Armature, and shunt wires.

Next up: We'll start taking apart the stock chassis.
