BTW, using your Rocksim file, I get a dv of 11.5ft/sec using the A3-4T as a sustainer. Altitude is less school-yard-friendly at 642', but it seems like a reasonable motor option, space permitting.

I seem to be getting higher Dv's on my runs, anywhere from 20 FPS up to 36 FPS. The test with the 1/2 A3-4T gave me the Dv range I liked, so I kept it.

Also, an early test was using a 1x24 streamer, so the altitude risk could be reduced.
