I am new to 10th scale and I am looking at getting into indoor racing. I am debating between the XB4 and the D413 (leaning towards the xb4). I would be going with either Tekin RSX or Orion R10 or Viper ESC. The tracks I would be running on are med size (nothing large). What motor would you all recommend... 6.5, 7.5, 8.5?
And are there any upgrades on the XB4 I would want to do off the bat? I may buy the 2015 but maybe the 2014. with 2014 I would want to do the steel diff gears right? And I also like the idea of a CD. Do the 2015 come with the CD? or do you need to buy that separately? I hear everyone say that xray parts are more expensive compared to others like the D413. Is that a big deal? I also hear that the xb4 is tough and won't really need replacement parts very often.
