What a huge blunder by those who claim to be responsible for this forum and boosting the Xray brand! Didn't Hudy just release his own brand of engines?
Here this guy is all excited about buying his new truggy and responding to the advice in the manuals about "Award winning support"....
Y'all should be ashamed.
Max, I will suggest that you look at the RB engines. I have had very good luck with mine. However, I purchased a .21 for mine that "works okay" but I think it needs a little more power. Some argue the .21 is enough to win races with in a truggy and they provide better fuel mileage than a larger .28+ In a long main race that extra mileage may mean something.
O.S. SPEED is also a VERY worthy consideration.
There isn't much information available on the FX engines other than advertisements. And obviously, nobody at Xray is paying any attention to this forum.
