Here are my weights (including wires and connectors:
2200 20C 3s 170g
2200 30C 3s 195g
2800 25C 3s 240g
2200 30C 4s 255g

To balance on the step, the 4s has to protrude about 1/2" into the compartment behind the battery channel. (I removed the bulkhead at the back end of the channel.) This is not an issue as far as I'm concerned, as there's lots of room for everything.

Hoping to get out and try 4s this afternoon. I did a brief flight on 3s this morning but the wind picked up and it was too bumpy for safe and enjoyable flying.
