I went did a little more testing with my 26" mini rivercat today. The first outing was with a castle 1512 2650kv motor, x438 prop, 50c 5000mah 2s packs run in series. I was wondering if I went to a lower kv motor (same exact motor) with more voltage, pretty much the same rpm, would it be faster. Well today my question got answered first hand. I'm sure a few of already know, but doing it first hand is priceless to me. So here's the first run, 4s 2650kv
now here's today. Switched motors. I didn't know castle made a 1800kv version until.a couple weeks ago when a member put one up for sale. I used 50c 5000mah 3s packs for this run. Motor ran cooler too at 95.5f. Other setup ran a little over 100 degrees.
tell me what you think. I feel like visually it's a big difference and sounds like the motor isn't straining as much. Here's the rpm difference, unloaded rpm with 4.20v per cell:
4s, 2650kv is 44,520rpm
6s, 1800kv is 45360 rpm
