The fuel is great and tuning, performance and runtime is as good if not better than any fuel I have used.
The Nitro X fuel I use is HP173.
Totally agree. This fuel is great, leaves the engine super clean and provides engine longevity. I've been told that hp173 has a very refined degummed castor oil. This is the reason for little to no carbon buildup.
