Thought you'll might like to check this out. http://www.youtube.com/watch?v=nLY9EGOfwOc 47 mph Just bought it yesterday.Novak 4.5 with 14/68 gearing,Dirt bonz,and ebay budget 8000mah lipos(best bang for the buck cells out there imo)It's my normal setup,but the first radar of that speed.I have good luck with this combo and am really starting to doubt whether or not the medusa 2000 is gonna make me happier,but I should get it this week and see.The quark 80b is modded with heatsink and caps,all wired up ready to go.Any bets on top speed out of the medusa on 4s?I,m thinking I'll be lucky if it's faster.
