Well "it felt hot to the touch" isnt really accurate. I agree 1400kv on a 4cell is slow you need 1800-2200 for 4cell. 6cell will be even cooler actually. Normal operating range is 130-160F. Also remember what you temp the outer can at can be up to 50Deg F hotter at the core. If it over heats in the core it could loose magnetism. That over heat is 200-220Deg F.
Personally i run a 4s 1900kv tekin set up with a losi 8E body with front windshield cut out. this gives me 5 vents of cooling and I run about 145F. Speedo about the same temp.
