Hi folks.....

I have over the years collected some good info on setups, props, engines, rpm, etc.... with respect to various pattern setups. Everything from Veco .61 power up through OPS, Rossi, webra, Picco, CMB, ST, YS. And more recently I have had to dig out the old notes in an effort to help a few getting involved in vintage pattern or BPA sorta setups.

I know there is a weath of experience on here. Maybe others might find a thread full of answers a good resource.
Thus I though I would open up this thread to see what others have in their notes, or what they achieve now with different pattern engine setups.

For the sake of simplicity here, lets limit this to 2c setups. Most would be expected to be .40 to .61 size engines. Other size modern engines can be included as well as they provide an excellent reference.

In particular, identify the engine, exhaust system info, prop used, rpm observed.
For exhaust system, note if it is on a stock muffler, aftermarket muffler, or pipe.
If it is a pipe, note the pipe length (glow plug to divergent seam/weld)
Also identify your location.

Have at it.... next time you have an opportunity to run your ST bluehead, or Axe Rossi, or what ever in between.. take an observation and post it here. If you have old notes that you believe would be useful... post them here too.
