I am sure this has been covered, but whats the latest greatest headers for the DZ engines? I saw the NMP headers, how are these holding up? what else? Its for a Impact and YS.

NMP is a good header, that's what I am using on my Impact with the 160 DZ, it has a larger opening than the old style header. However, be sure to get the header brace for support.

I've been having really good luck so far with the NMP on my 1.60's.

ok thanks, thats probably the route I will go. Riot, which pipe are you running in your impact?

I've been using the Johnson pipe for a long time. I know its a bit on the heavy side, but, it has a fairly large diameter opening. In addition, you just can't beat the price.

The Hatori 822 header works great withe the 821 pipe. Best I've ever used and I' tried almost everything. Haven't tried the NMP header though by a friend of mine has and it broke. Maybe he didn't mount is correctly. I know its a great product. I am just saying that the Hatori one is great too.

I use a Hatori 796 cooling header with a world models pipe and header soft mount on my 140DZ. Works great!

my nmp header broke after about 30 flights installed a support with the new one

Gary,

You do need the header brace, plus I would recommand a soft mount on the middle part of the teflon connector. My NMP had over 150 flights without any problem

The Asano is very good and very expensive!
built in mount that bolts to the head of the DZ

Im using the NMP header w/brace, a CF pipe from Central Hobbies and a 15x11 4B prop. This is a really impressive setup. Really really powerful, quiet and has held up exceptionally well so far. I would guess I have about 50-60 flights on the plane thus far. I took Troy Neumanns advice and used the NMP header washers and tightened up everything with the engine hot. This made all of the difference in the world. Before I did this the vibration from the 1.60DZ would knock the header loose from the engine every 2-3 flights. After I got the washers and did the hot trick, that was it.. I still check it for tightness every few flights and I have had to snug it up a couple of times but not but about every 10-15 flights or so. A really low idle on the ground produces a HARD lope, I think that is what loosens the header. I have learned to keep the idle up just enough to smooth it out on the ground then ease my idle slider down once Im in the air.
