RE: HPI E-10 vs. HPI RTR Sprint 2 Sport
Accountmaster.. why would you think that the Traxxas Velinion system is an upgrade over the Flux? Most of the new sprint 2's come with a Castle built 4 pole 5900 kv and esc. Even the older Flux systems had a Castle 5700 2 pole that is just about the same as the 4 pole. torque in a light car doesn't help you. I like Traxxas but not a fan of the Velinion.. We run Sprint 2's and older RS4's every saturday at our races and nobody runs a Traxxas setup.. everyone runs Castle.. The system you mentioned will work fine, just not an upgrade from what you have. I would use the 2075 servo as its a great match for the car. I run them in all my touring cars. Cheap, fast and digital.. a good combo..
