Brushed speedo with 1s lipo.

[Chris Elworthy]

Hi lads,

I'm getting my old mardave up and running for the winter so have a few questions. Firstly, will a basic old brushed speedo such as an MTroniks digi Sprint or LRP v7.1 work properly with a 1s lipo (Orion 5500 90c) and silver can motor?

My Mardave is the original type with aluminium chassis and solid axle. The car is ball raced but are there any other worthwhile upgrades before I start? I'm intending to just run the car without the diff for now but things appear to have really come on in the last 6 years since I raced them.

Finally, this isn't so imPortant but I am curious. When reading the rules for the GT12 nationals the specifications for the GT12.2 class state that you are not to use any parts not included in the kit. Does this mean you cannot fit ball races? Turnbuckles? Add spacers for caster? It is a little confusing.

If anybody can help please let me know
