Week 1 of our www.hpiracing.com RS4 Sport3 Creator Edition radio-controlled car build-off is in the books and we have a lot to accomplish over the next few weeks, including installing all of the model’s electronics, trimming and painting our Mustang body, and gluing up a set of cool wheels and tires. If you missed out on our Week 1 build-off intro and video click on over to see it HERE before you check out this week’s video below.

For week 2 of the build-off the build-off participants, which include Chris de Graaf of Hemistorm RC (www.hemistorm.com), Greg Vogel of RC Driver (www.rcdriver.com), Kyle St. Peter of FotoGuy RC (www.fotoguyrc.com), and Rich Morgan of The RC Network (www.thercnetwork.com), were instructed to assemble the model’s electronics and prepare the RS4 Sport3 for Week 3, where the model’s body, wheels, and tires, will be unveiled and fitted to the car.

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! Enjoy this week’s update!

Powering our HPI Racing RS4 Sport3 Creator Edition will be the company’s 4-pole brushless motor and matching electronic speed control. This package will offer plenty of punch when we grab a finger full of throttle on the transmitter. Additionally the speed control is fully programmable for various throttle curves, and power levels.
3-channel digital radio is the company’s standard transmitter/receiver combo used in its ready-to-run (RTR) radio controlled models, and that’s good enough for us. The built-in third channel is great for running optional electronics or lighting.
To steer the model uses a geared device called a servo. The servo attaches to the steering linkage and connects to the radio’s receiver for power and steering input signal from the radio. Here the servo is being prepped for installation by adding the kit’s provided servo saver assembly.
Obviously we’re going to be building a Mustang-based model of our RS4 Sport3 Creator Edition. However, all we’re going to give up this week is that it will be using HPI Racing’s 1966 Mustang GT hardtop body and a staggered set of these matte silver vintage five-spokes, also from HPI Racing. You’ll just have to watch Week 3’s video next week to see exactly what we do with these bits.
