I bought one of those cheap GoolRC 540 size brushless motors that is finned with just 380 size guts. I had a Sidewinder 3 SCT esc in my spare parts bin. Which forced me to sacrifice one of the battery bays for it. At least the 2s batteries it uses are small and pocketable. I won't be able to do a full proper test till tomorrow but the little I could do around the house gives me high hopes.
