O.S. 21XZ-B V-Spec Thread

[superrcracer]

I run the O.S. 21XZ-B V-Spec ad gives me about 7 to 8 minutes of running time. The O.S. 21XZ-B V-Spec is an easy engine to tune and hardly needs tuning. Its one of the best engine I've owned.

Do you run it in a truggy or buggy?

I usually run it in a buggy and sometimes I swap into my truggy. This is one of the best engines I've owned. On my truggy I usually run the O.S. Speed 21XZ-B Spec II. The two engines are about the same the XZ-Z is probably to much power for the buggy.

What pipe are you using for that engine?

7-8 minutes in a buggy or truggy? That doesn't seem much, I get about 12 min from both my OS and my novarossi...

From a buggy I get 7-8 minutes. How do you get 12 min of running time?

I run my engines at about 215-225 degrees, I run the P5 a little bit on the lean side on the bottom end and then adjust the top so it run smooth and consistent. On my OS I lean the bottom as much as I can, not too lean though, and a little leaner on the top than the P5. My first OS lasted over 8 gallons that way.
I'm not sure if it makes a big difference, but I live in the desert, the weather is usually warm and very dry...

I think you probably run it too rich.

What pipe are you running?

I run the O.S 2060 pipe. 

[kyoshoracer]

Have you just broken the engine, and are you still running it on the rich side?

Do you ever use the P3?

[elreto]

Glowplug? Yes, that's all I use.

I run the O.S 2060 pipe. 

I use the Losi E11, I've been told that this is a copy of the OS 2050. It's been a very good pipe for me.

Have you ran the 2090 pipe?
