OFNA Racing


Nitro R/C cars are getting faster than ever. It seems that companies are now using top speeds as a selling point for their 1/10th nitro touring cars.

Leading the pack is the OFNA OB4. This is a belt driven 1/10 nitro powered touring car powered by a .12 Force engine with pull-start. Other goodies include a tuned pipe, 2-speed transmission, full ball bearings, oil filled shocks, rubber racing tires, and a good Airtronics Blazer Sport radio control system.

Reviews and Feedback

Here are some positive reviews of the OB4 and feedback from the OFNA forum...

I've been running the OB4 Pro for two seasons now (outdoor parking lot club races) and it's been great.


I've had my OB4 for three years now, It's gotta be one of the toughest cars that I have, never given me a problem. The engine finally went after 5 or 6 gallons.


yes, i have 2 of them, you will have to buy a spring kit though. yellow on front, blue on rear. 60wt front 40wt rear. this car, pro version anyway, is tough, but i can break anything by hitting the boards at 45mph. keep it as low as possible, torque roll is vicious!!!
