Essential Hop ups for the DB01?

[SigmaF]

Chaps,

Quite fancy giving some indoor winter racing a go....first time really so looking for something simple and durable....and potentially competitive in the right hands!!

Although I suspect that I should be looking at a B44....I still seem to have a youth affinity with Tamiya....so, here I am...

Looking at the DB01......a local shop has one super discounted to about £150.....new....or, a couple of places online have the DB01-R.....for about £210....

All things being equal and my lack of patience, I'm very tempted to get the DB01 and go with that.....but, I know that it needs some hop up bits........the list however is endless!!

I suppose that by the time I buy a shell and tyres for the DB01-R.....I'm up to about £230.....

So, the question really is what are the essential hop ups for the DB01?

Would be really helpful if you could point me in the right direction?

Guessing a slipper clutch, some better dampers?

Thanks all
