A .28 is probably overkill but the same info would apply to a .21 also. Because a NX .15 is a big block it shouldn't be that much trouble to swap in a .21 or larger engine. Top speeds will be the same between the two but acceleration will be greatly improved with the .21 or larger engine.


Poor Judgement, It is going good. The MT2 is just about the only nitro that I have left. I have gotten or am about to get rid of the others since I have discovered the ease and reliability of the 1/5 scales. The MT2 was my first nitro and I am going to keep it due to sentimental reasons.
Have you moved on to another brand or are you taking a break for awhile?
