Chassis Focus – Simon Kurzbuch (Mugen Seiki)

Chassis: Mugen Seiki MRX7
Engine: Ielasi Tuned Pista
Exhaust: Ielasi Tuned EFRA 2196
Radio: Futaba 10PX
Servos (Steering/Throttle): Futaba Ct702
Body: Xtreme Hyper
Tires (handout): Matrix
Fuel (handout): Energy

Notes – With the MRX7 only just recently released, Simon is running it pretty much straight out of the box. Using a Hiro Seiko screw set in building the car, the only modification for the World Championship is a cut in the front of the radio tray for extra flex which Simon said made a quite noticeable different to the set-up. On the clutch Simon is using a spring from Italian specialist BM Clutch Spring.

Having hit a landmark of telling our 50th World Championship story when we reported on Marcus Kaerup’s 4WD Buggy World title win in Australia, Red RC is excited to be travelling to Chile to cover IFMAR’s fourth & final World Champion crowning race of 2025, the 1:8 Onroad World Championship.

The F1 of RC Racing, this will be our second time to Chile this year having covered Alessio Mazzeo’s 1:8 GT World Championship double there in September. With our 1:8 being made possible by Capricorn, Radbody, T-Works, and IFMAR, this one is special because it was IFMAR’s original World Championship category that was also the first World Championship to be covered here on Red RC back in 2007 in Argentina.

Our coverage from Santiago and the CACH Facility will start on Tuesday (Dec 2nd) with seeding practice through to the crowning of a new World Champion on Saturday (Dec 6th).
