hmm sucks about the velenion for you, i have the 5000 3s, and i run the whole pack which is about 30 mins and its definatly warm to hot, but not to the state of thermaling, thats also running stock gearing which is good for 56mph, bump it down a bit and it goes forever, but i agree about the mm, i have that in my revo and its awesome! i love plugging it into the computer, makes you feel like your doing surgery to it or something
