Ive just run in an sworks s7 which is the same as an xzb (spec 1).
I ran it at a race meeting yesterday with a dynamite 086 pipe. Although there was loads of power the fuel economy wasnt great and i was only getting about 7mins 30 secs on a tank.
Can anyone recommend a pipe to run with it that still gives plenty of power but with decent runtime? An alternative to the os pipes would be good as they are a little pricey.
I like the look of the losi pipes but dont know if they would work well and which one to choose?
I was also looking at a jammin jp4, anyone had any experience of this pipe on a xzb? (i like the fact its a hardcoated and cleans up well )

I paid $250 for mine with an sworkz tb1 pipe which i haven't used yet.

The s7 is identical with the speed 1 right??
So why they have differences?

The Losi pipe, RE10 and RE11, are copies of the OS 2050 and 2060, they work great, and they are hard coated Black.
And they are in the price range of about 60 bucks with header included.

I reckon i will get a sworkz 2089 pipe which is the same as the os 2090 which everyone says works best with the XZB range.

Do you know what the prices are on these pipes?

Heard it's a XZB Spec 3 but no info on release date yet.
There have been lots of complaints on runtime and the VZB bearing issue seems to have resurfaced.
The first XZB Speed had no bearing issues and had good balance, the spec 2 on the other hand is having main bearing issues and I suspect it is because of the lightened piston and rod. My theory, and it is only a theory mind, is that the slug needs to be omitted from the crank. It will be interesting to see what changes are made.
I have rebalanced one of my Spec 2's (the same way I did the VZB's) after having a main bearing fail after only 6 litres and so far it has done over 15 litres with no more issues yet. There was no rust or anything done to cause the failure of the first bearing, it just got notchy so I changed it.
