    Top Fuel 33% Nitro

    Was dusting off a Nitro Tec 4 that my son received a while ago and we were planning to run it this weekend. The manual states that this model should be operated on Top Fuel 10% or 20%. The local hobby shop only had Top Fuel 33% nitro in stock. They said it replaced the previous blends across the board.

    Does anyone know of a product or service bulletin covering this change???

    The fuel can states that it can be used with the 2.5 TRX engine.

    Thanks for any assistance until I can contact customer service on Monday... they were closed today when I called.

    My lhs still sells 10 and 20%.
    I tried being reasonable, I didn't like it.

    Top fuel works great, 20% or 33% in my old 2.5R's. The switch to 33% really gave quite a boost.
