Dex210 kit/RTR

[marley]

I purchased the dex210 RTR a couple of weeks ago and while looking at what spare parts to stock up on I ended up just buying the whole kit as they are cheap right now.

Can anybody advise me in the best parts to use from each box (eg ball diff or geared diff etc) and any upgrades I should be making. I will be racing outdoors on astro turf so was planning on running mid motor, I have also ordered a better servo and have replaced the RTR tyres.

Thanks
