I have a triple-x NT with the dynamite mach .15 engine. i am wanting to put a new cooling head on it if someone could point me in the right direction on some that would be great.

I'm not knocking the engine that you have or anything, don't really know anything about it.. but here's something to consider - the new cooling head will cost you 40 bucks or so.. that's almost half the price of a new OS engine (.12 or .18)..

the reason I say this, I bought the bling bling head for my evader to fit the DTX .18, I started having problems with the engine, and a couple of weeks later, I replaced it with an OS engine, now I have the spare head sitting here and nothing to do with it..

I do not know anything about that engine either but I would not change a head unless I was having a cooling problem. Are you having a problem with the temperatures or do you just want eye candy?

I am an OS man and if the engine you have is not up to par I would recommend instead of getting a head I would get a whole OS .18 or .12 CV-R series engine. Or if you want all out power for twice the price get a OS TZ.
My TZ is on the way.

i agree with the previous posts buy another engine....
is this the Mach .15 with the black head or the blue one
if it is the blue one don't waste ne money on a head being how the engine wont last long anyways (past experience)
if it is the black one i heard that it last a little bit longer that the previous model
but still don't buy a head for a rtr engine
invest in a good engine like stated in the other post (fantom, o.s,Novarossi, rb,picco......)

As someone wrote in a later post,

"How about a cooling head with a free engine below it? "
