Fastest Custom Made RC Car – RC Bullet
Nic Case is making history with his creation – the world’s fastest RC car, the 202mph RC Bullet. Not only does he have the Guinness Book of World Records certification to prove it, Nic is pushing boundaries and challenging himself to build a faster machine capable of reaching greater speeds than ever thought possible. As the record-breaking driver behind this supercar on 12 cells, Nic is delighted to show off what he can achieve, taking excitement and adrenaline to a new level.
To many enthusiasts watching on, words alone are simply not enough when it comes to understanding how fast this vehicle truly goes – until they see it in action. “How fast does it go?” It’s a question fascinated onlookers continuously ask as they witness all that Nic has accomplished and marvel at the capabilities of his creation. Most importantly though, Nic continues to develop and refine his model day by day in order to exceed expectations and reach ever-increasing accomplishments. Ultimately, his work will be remembered for years to come as an impressive representation of what can be achieved with effort and dedication.
The design of the RC Bullet was largely derived from multiple brainstorming sessions with a close friend of Nic – John Trino. They both agreed to retain the streamliner design layout while completely removing the suspension system.
This decision was made to prevent rear squatting during acceleration and minimize the risk of a blow-over. Additionally, eliminating the suspension also addressed the weakness in the constant velocity driveshaft (CVD) that was present in previous versions. After careful consideration, they opted for a belt-driven system instead of a shaft-drive because it was easier to find a reduction ratio close to 1.5 : 1. Using CAD software, they designed the RC Bullet’s chassis, drivetrain, and various body options during the spare time.
Drive Belts for Industrial Use
The Bullet utilizes 6mm and 8mm drive belts that are commonly used in small machinery. However, it was decided to opt for slightly wider belts to ensure durability, even if it meant a bit of overkill on width. These belts come in various lengths, providing flexibility in design.
Custom Carbon-Fiber Wheels
A significant effort has been invested into the tires and wheels of the Bullet, as they need to withstand speeds of over 23,000 RPM during a 200+mph run. Experiments with different combinations of materials, adhesives, and processes were conducted. The tires are made of a high-quality purple foam from John’s BSR tires, expertly glued by John Foister himself. These tires are mounted on custom-made carbon wheels fabricated one at a time. The carbon-fiber wheels offer a superior weight-to-strength ratio and do not suffer from the drawbacks of aluminum wheels.
Dinogy Lithium Batteries
After conducting research, it was discovered that Dinogy batteries deliver higher wattage compared to other batteries. Switching to Dinogy packs resulted in a speed increase from 171mph to 184mph! As a result, twelve 5000mAh cells were connected in series to provide the necessary horsepower.
Although originally designed for RC planes and helicopters, it was decided to adapt Neu motors. These motors are known for their power and efficiency, with temperatures never exceeding 150°F. Many records have been set with Neu motors.
To ensure the Bullet’s chassis is rigid enough, a high-quality 3mm carbon fiber for all the components was used. Kinetic Composites cut the carbon fiber pieces, Team Tamale cut the aluminum parts, and John Foister at BSR machined the front axle and hubs.
Castle Creations Power System
The Bullet’s Electronic Speed Control features a Castle Hydra HV 240 with a Phoenix HV 110 Control board, although it’s an older version without a data logger. A large capacitor bank to protect it from current ripple was added.
Futaba 4PK Transmitter and FASST R614FF Receiver to maximize signal strength with an added 400mm boat antenna that threads up the back of the tail fin on the receiver. This ensures that the antenna is positioned as far from the ground as possible, utilizing a Futaba 4PK Transmitter and FASST R614FF Receiver.
The original carbon fiber body for the Bullet was hand-carved from modeling clay. Only two versions of the body, Version 26 and Version 19, were ever used on the Bullet. To refine the design, CD Adapco’s virtual wind tunnel was utilized, providing valuable insights into the relationship between drag and downforce. This scientific tool helped confirm if the visualized design was aligned with the desired direction. Multiple iterations were made, as some designs exhibited excessive drag or inadequate downforce.
