Here are my 5 pros (here more than 5) and only 4, but pretty fundamental suggestions for improvement:
+ great parts quality
+ general tolerances f.e. of the CFK parts
+ awesome setup-book and instruction manual
+ very smooth diff
+ great ball bearings
+ nice orange colour
+ possibility of adjusting the diff without having to disassemble anything
+ although it is not mentioned frequently, I have to admit I love the body posts with the movable body holders at the top (not that stupid clip like in other cars)
I would suggest the following improvements:1. please stop this extrem-lightweight-trend with parts like the rear drive shafts which were made of aluminium in the 009; I don't know any even serious racer who cares about the part beeing 1 or 2 grams lighter but with soo much reduced lifespan/crash resistance
-> better you make those important parts not lighter until they get so easily breakable, but you don't use steel screws but titan screws in the kit! That means a total weight reduction of about 35 grams! That's what I call effective!
2. make a car which can
really benfit from the lightness of a LiPo battery! I would move the electronics side as close as possible to the centerline; especially the motor should get special attention here: Schumacher already showed one solution possibility with the release of their Mi-4 chassis: they designed that aluminium-ring, into which you insert the motor. If you use LiPos you can stick the motor more into the ring and turn the shaft with the spur gear around (long front belt at the right side of the chassis - moves the light LiPo side more outside and the electronics side closer to the centerline =>

) - see here:
http://img-up.net/?up=mi4_motorFGr58AV.jpgSuch an average LiPo is about 200 grams lighter than a 6 cell pack, that means we could theoratically drive around with a weight of about 1250 grams! Imagine the gain in speed, maneuverability and the minus in tire wear!
3. the price is already - let's say not cheap - but you get a good quality for it. I could get over a further increase of 15% (that is at least about 68 Euros recommended retail price = about 95 USD) if you include usable aluminium dampener and those ECS - shafts in the front; a third thing would be aluminium steering arms as they wear out pretty fast in plastic version. Also a must: a BIG "last-aid bag" that includes all those little clips (of each 1 piece included) for which you normally would never buy a pack of 10 as spare parts and pins as well as maaany aluminium spacers (also for example one or two balls for the diff which get lost veery easily during re-built)
-> herfore do not include a spur gear as well as oils and lubrication things in the kit - we have competition level here and racers already have those things
4. in my personal opinion the steering unit has too much tolerance, especially after the first 50 or 100 runs. Maybe you could think about a solution like the Tamiya cars have without the servo mount standing out of the side chassis (LiPo height about 24mm, servo less than that, so you should theoratically be able to move it under the topdeck; also contributes to LiPo left/right weight distribution! - also as close to the front as possible in order to gain more room for big electronics such as BL ESCs)
So I really thought about the whole issue and tried to explain it here; I hope I get heard.
If that works, I am convinced Xray will gain even more in popularity.
Thanks.
