Great to see another 'JRX' graphite chassis Losi being given some love! Are you intending to run this beauty or is it for display only?
I ran my 5-link JRX-2 during last year & I must admit it drove really well & I was impressed with how it stood up to the riguers of running with modern Brushless & LiPo electrics (I did run a slipper though). I also a have a Pro - would be interesting to run that one day & compare it to the older 5 link SWB car.
I would highly recommend running your vintage - it really adds to the fun of owning these older cars
