I would have to admit that the caps the castle uses are undersized. Novak uses fair sized capacitors on all their escs. I'm not saying it wasn't an MMM related problem that caused the failure, but if you think about it, even though the truerc packs may be true 15c packs, thats still only 75 amps continuous. Castle claimed they saw 800 amp spikes in their setups during prototyping and that was probably with a 1y which is even lighter than a 1.5D. From my experience, I noticed a huge gain in peformance when going from 20c 5000 mah maxamps packs to neuenergy 30c 4100 packs. My novak hv4.5 turned into a completely different motor. It suddenly had more punch than my 8xl did and i could gear down 2 teeth on the pinion gear without sacraficing any top speed. Before I made the change, I totally judged the motor based on peformance since the packs were barely getting warm. Once one of the cells puffed, and then two more while the rest of the pack was sitting on the shelf, I soon realized that batteries are a HUGE factor in determining performance. This was only in a 7lb 8ight, so think of how much of a difference there would be in a monster truck that requires even more power for even higher speeds, with say 125 packs verses 75 amp packs.


Check out my custom converted 8ight:
