I roast most beans for my personal use in my Hot Top. I have never used the RK drum for them.
I do kn ow that the horse takes longer to roast and 1st crack is later with horse. I am not surprised with 4 pounds at your times.
How did the roast end up?
Let me know when you have tasted it, it it lot 19?

I find with larger drum loads that the heat has to go up more, to compensate
for the larger, cooler bean mass, and not let it bake...
Just my 2cents,

When using the RK drum is it ideal to have first crack at about 10 to 12 minutes?

Is there a general roast profile that most people are using who use the RK drum?

To do a 3 pound roast ( I donít like doing 4 pounds)  I  preheat to 600 (with the digital temp gauge remaining steady).  I then put in the beans and make a note on a graph I have of the temp the probe returns to in 1 minute.  I then make sure that I return to 600 by the 8 minute mark allowing for a steady even ramp.  Once I get to 600 by 8 minutes, I then just let the roast continue upward about 10 degrees per minute.  I would expect a 1st crack at about the 13 minute mark that that kind of load, maybe a tad before.   I have different preheat temps for each weight I roast.  I always return to the preheat temperature by 8 minutes and I have achieved great consistency.  The smaller loads, 150
 grams, 270 etc. I expect a 1st crack at 10 to 11.

Marc,
Bear in mind that the profiles at the RK site are usually from an analog 
thermometer and the actual numbers may be significantly different from your 
readings with the digital. My digital therm set up sounds a lot like yours. 
For 4 lbs I roast at 590f for a total of 18 to 20 minutes for FC to Vienna. 
Each roaster is going to be a little different from another. I try to keep 
all of my roasts below 20min to avoid possible baking. Good luck,
Frank Coster

My thoughts only - take your temps up 25 degrees, and stay there monitoring
the difference...

I preheat the drum so that all of the subsequent roasts start the same.
