This is RC Royalty. Gold and Purple have long been the royal colours.
The MST RMX already has a large number of upgrades available but this machine goes a whole lot further. Some might call it RC Jewellery.
For those unfamiliar with Max Speed Technology products, they have come a long long way in the last few years especially since the FXX-D and now with RMX and RRX. You can really consider them as a quality alternative.
This one takes it to a new level.
