As we alluded to in a recent Mustang-360.com news item HERE we’ve been invited to join in on an interesting build-off series with our friends from HPI Racing. This radio controlled car build-off focuses on HPI’s brand new RS4 Sport 3 Creator Edition R/C model. The Creator Edition, in a nutshell, is a fully assembled R/C touring car chassis that you finish off with the body, wheels, tires, and electronics of your choice to build the exact R/C car of your dreams.

Out of the box and ready for us to operate on, the RS4 Sport3 chassis has a lot of great features we discuss in this week’s video.

You’ve no doubt seen Mustang enthusiasts at shows/cruises with mini versions of their Mustangs zipping around the show field or parking lot. Now you can easily do the same without buying a complete R/C car with a body, wheels, and tires that do you no good in your quest to make a “mini-me.” We’ve built several scale R/C Mustangs for ourselves and friends in the past, so we’re excited to have HPI come knock on our door and ask to join their build-off.

We’re going to be stuffing the hottest motor HPI Racing offers for the RS4 Sport3 into this thing, so we’re happy to see an aluminum motor mount with cooling fins to support the torque of the brushless motor we’re using.

Fellow builders in the build-off include Chris de Graaf of Hemistorm RC, Greg Vogel of RC Driver, Kyle St. Peter of FotoGuy RC, and Rich Morgan of The RC Network. These R/C influencers are sure to be building something really cool with the RS4 Sport3 Creator Edition, so hopefully our Mustang measures up! Keep tabs on everyone’s builds on social media by searching for #hpibuildoff and keep coming back here throughout the month of February 2019 for our weekly build-off updates, but right now be sure to check out our Week 1 video posted above!

A quick peek under “the hood” shows the metal gear differentials. They will be able to transmit all of our electrical “HP” to all four wheels without issue. HPI Racing offers a spool too if you’re a drag racer or drifter. Note the complete drivetrain runs on sealed ball bearings too for less resistance.
The RS4 Sport3 chassis features a nice smooth bottom to prevent catching on transitions or other debris. Note all hardware is metric hex and not Phillips head, which is prone to easy stripping, and the quick access channel for the center driveshaft.
While the RS4 Sport3 Creator Edition comes completely assembled (minus foam front bumper and body mounting posts), the included manual not only shows you how to finish the Creator Edition by adding your electronics, wheels, tires, and body, but the manual has complete teardown/maintenance sections that shows you how to work on the chassis. The back of the manual includes a full part list by part number and several pages of option parts to upgrade your RS4 Sport3 as you grow into it.
