A few diesel readings
PAW 149DS on APC 8x4: 11000
As above on APC 7x6: 11000
(I'm not sure how healthy this motor is - it tends to vibrate regardless of the prop on it, and also revs a bit unevenly. Anyone have any idea whether 11000 is reasonable?)
PAW .15DS on APC 9x4: 10800
Replica Oliver Tiger MkII on APC 9x4: 12000 (just finished running in, so maybe a bit more to come)
Unfortunately this was all on a commercial fuel of unknown proportions - when I get hold of some ether I'll mix up some of my own and run them again.
