Funny you should mention the WildWilly 2. I just picked one up over the weekend when TamiyaUSA had them on special during the last TCS race. I agree, its the coolest little truck. I've got a huge stable of racing sedans but the Willy takes the cake.
The Mabuchi will be the first to go. Mine won't be slow - that is simply not an option.
Is there a web-addy for hopups???
