RE: 2stroke for pattern plane
Dave
I have been flying the OS 140RX with the OS header and the ES carbon pipe ESD2C140M8, I also have the Mintor twin plug head (23) purple. This has been a great combination. I run Cool power Pro-Pattern 20% and 25%.
Currently flying a Focus II with a 17x10N APC prop. Very nice power, vertical performance.
Hope this helps
