Some lessons learned about the PAW 19 in the Ringmaster: It can be started quit easily with a starter at the run settings from dead cold. It takes about a minute to fully warm and come in, so you need to start it and take your time, in the OTS pattern just about when you finish the climb and dive it will come to full power. If you increase compression to hand start you need to make sure to back out enough. On control line ships you need to go off between 1/8 and 1/4 turn rich from were it starts to miss, when it is warming up is may still miss even at this setting, need to get the feel for this, it will lean as the fuel load burns down an if to lean will start to miss at the end of the pattern. On control line ships narrow long tanks are better than short wide ones to reduce the fuel head change due to centrifical force acting on the fuel.

So far this is what has work well for me, again thanks to all the input and information from this site.
