Newbie seeking advice

[Brettnai]

This is my first post on the forum so firstly, Hello!

I've recently purchased a Cougar KF from eBay. I know very little about the technology now which seems to have moved on considerably since my Tamiya Lunchbox days in the early 90's.

The buggy I've just bought seems in mint condition. I paid £130 which included all electronics and a new Absima transmitter. I'm just waiting on a Lipo battery and charger to arrive, then it should be ready to roll.

I think the electrics are all quite basic so I'm keen to upgrade as soon as possible. The current motor is just a standard Saturn 20T (means nothing to me) but I'm guessing I should be running a brushless?

If I upgrade the motor, will I also need a new esc? I've seen some combo deals available. Will this also mean a change of gearing?

If anyone could recommend a decent motor and esc combo that won't break the bank but be good enough to race with, that'd be much appreciated!

I live in Stotfold which is handy! I went up to watch some of the Winter Series this morning and now I'm itching to get racing!

Thanks all!
Brett
