SP LPF speedo question ?

[MHeadling]

I have borrowed a SP LPF off a mate for my B44 and it's cogging ever so slighlty off the bottom end of the power.

I have a brand new losi 13.5 (I'm not a girl, it's for indoors at Faversham!) and a new sensor lead.

All the EPA are set ok to 100.

One thing I have noticed is that there is no capacitor on the + / - ? Will this be having an effect?

I want to give the car a run on Wednesday.

What does the capacitor do? Can I use any other type, ie Novak?
