Spare parts
Do you need small plastic parts, I have a large selection of aftermarket custom-made parts to fix that.
I have Battery covers for your RAX300 remote + the cover for the remote receiver as well.
All the rollers you could ever need are available.
if your PTP70II needs a new plastic backshell let me know I have them.
Have side panels fallen off? I have the brackets to secure them in place.
