Gas Powered F1 RC Car: FG 1/5 Formula 1 and What It Takes
The best-known gas-powered F1 RC cars are FG Modellsport’s 1/5 scale Formula 1 models, made in Germany. The F1 Sportsline comes ready to run with a 26 cc petrol engine and reaches nearly 100 km/h; the F1 Competition is the racing version with a Zenoah 26 cc engine, airbox, tuned pipe and, in its 2026 version, FG hydraulic brakes front and rear. They run on petrol mixed with two-stroke oil and are raced in large-scale on-road classes. Here’s what they are and what owning one involves.

What makes a 1/5 F1 car different?
- Size: about 1/5 of a real F1 car; heavy, with a big presence on track.
- Petrol power: two-stroke engine with clutch and 2WD drive to the rear axle.
- Open wheels and wings: look and handling like a real formula car; wheel contact means crashes.
- Brakes: mechanical or hydraulic disc brakes instead of motor braking.
- Needs smooth tarmac: very low ground clearance.
What else do you need?
| Item | Notes |
|---|---|
| Radio | Included on RTR; racers use high-end pistol-grip radios |
| Receiver battery | Powers receiver and large servos |
| Fuel | Unleaded petrol + two-stroke oil at the engine maker’s ratio |
| Starter | Pull start or electric starter box depending on version |
| Tools and spares | Spark plug, air filter oil, spare wings and suspension parts |
| Track | Large-scale on-road track or large smooth car park (with permission) |
Running a gas F1 car
- Break in the engine with a few tanks at moderate throttle and a slightly rich setting.
- Warm up the tyres before pushing; cold tyres slide.
- Check brakes, steering servo and linkages before every run.
- Keep the air filter clean and oiled; dust destroys small engines fast.
- After running, clean the car and check screws for vibration loosening.
Setup basics for a 1/5 on-road car
Large-scale on-road cars are set up much like their smaller electric cousins, only with heavier parts. Start with the manual’s baseline: ride height, camber and toe on the front, wing angles front and rear. More rear wing adds stability at speed but reduces top speed; more front wing sharpens turn-in. Tyre choice matters most: compounds for warm or cold tarmac make a bigger difference than any setting. Change one thing at a time and write down lap times or how the car feels, so you know what each change did.
Alternatives
- Electric 1/10 F1 cars (e.g. Tamiya F104-based kits): far cheaper, race indoors and on small tracks.
- Other 1/5 petrol cars: touring cars, buggies and trucks with 23–30 cc engines, such as the King Motor Baja 5B (which I own) for off-road.
Large-scale petrol cars are a big step in cost, space and noise compared with electric cars; check local rules on noise and where you can drive.
