Hello, I’m looking to upgrade my Traxxas 4tec 3.0 Corvette to brushless, I am considering 3 different brands, Traxxas, Spectrum, or Castle Creations. I’m really not sure which brand is going to be the best. I want something cheaper but I don’t want to buy some random cheap combo. Traxxas velinion system seems pretty reliable and fast, but I have never had one. Spectrum I have in an Arma and I have found it to be a pretty good and reliable system. But I’ve recently been looking at Castlecreations. What brand do you guys think would be best? Or does anyone have another brand for a reasonable price. I’m looking for 3s power that can take me to 70mph. Thanks
