Question: How much Nitro can I use in my VMAX 46PRO or 52PRO?

Answer: The 46PRO and 52PRO run well on 5% Nitro. The maximum recommended is 10%.

Better Answer: Using more than 10% nitro in the 46PRO or 52PRO is not recommended. Please review the instructions. Using more than 10% nitro will generate less power than 10% and generate more heat and lead to premature wear and engine failure. The VMAX 46PRO and 52PRO has been designed to give maximum power and longevity using 10% nitro or less.
