Still a role for the 3 gear box?

[ianjoyner]

I'm racing on a tight grippy indoor track at the moment. I can't help but think a 3 gear box may work here. The brass fly wheel feels good, but I'd like more of the effect without having to add weight!

Anyone still try the 3 gear?

I'm not sure what's involved, or if it's possible to fit to the squared car. I notice the DEX210 has a 3 gear option, but don't know if anyone uses it. Also I imagine the DB1 feels more like a 3 gear.
