Upgrade Advice

[Martinst]

I'm after some advice for upgrading my electrics on my car. Having not been racing for years I bought a TT-01 chassis ( basic I know ) but I wanted to make sure I still could drive. Its hopped up with most alloy upgrade parts etc, but I'm still running it with my old Tekin 411G and Reedy Sonic S motor. It rapid, but I fear due to the age of the gear I'm guessing it'll fail some time soon.

What is a good speedo / motor combo ? bearing in mind that I'm planning to upgrade to a B44 or road going equivalent in the new year.

I noticed a trend for brushless, but is this really for topend competion purposes only ?
