Hey how'd you get that rate of climb and target temp info added?
Playing with my new toy, I have my HeaterMeter hooked up to my 18" WSM via an "air burner". Thanks Ralph Trimble for the advice on the air burner.

I've got a 9ish pound (pre-trim) butt on now... but I keep losing temp and I'm getting a bit frustrated. This is only my 3rd or so cook with the HM/RD3 and probably only 8th or so on the Joe and it's been much the same story as the previous attempts. Anyone with advice? Thanks!!

I missed the live cook, last I recall you were tuning the air burner holes for high-ish temps in the WSM... If you were cooking low and slow today and the HM is running at 0% output I would first try closing the top vent a bit so the HM starts to kick in, that way it can back down if you start to get overshoot. If closing the top vent doesn't make the HM tick up a bit then put a screw in a few of your air burner holes to close down the air path a bit, or swap out the pipes for ones with fewer/smaller holes.
David, did you calibrate the servo so the RD3 is closed at 0% and fully open at 100%? The SPD numbers should be roughly 700-2100, it should be closed at 700 and opened at 2100 with inverted NOT selected. You can run it inverted if you want, it would just rotate the other way and you'd have to orient the damper disc the other way. I posted more detailed info about servo calibration in the RD thread fairly recently, check it out if your RD isn't opening/closing properly.
Seems like you have a handle on it though, whatever you did about a half hour ago set your pit flat on 250F...
