I've preordered the k2 hopefully it'll arrive tomorrow or Monday. It's my first 4wd so can anybody suggest a good stating point for motor turn and gearing. I run on a medium-large size Astro track and I gear my 2wd kf at 76 spur 24-25 pinion with a 7.5 motor if that's any help. I was planning on building the kit pretty much from the manual and then working from there but are there any essential additions/upgrades that I should fit straight away. Thanks Andy
