How to Make a MANUAL Clutch for the Toyan V8 RC Car | Stirlingkit

If you've been following Youtuber JohnnyQ90 lately, you know he's currently building a glorious miniature V8-powered RC car from the ground up. q90 He is a mechanical fan. In his videos, he can often be seen using a variety of tiny engines to demonstrate and better understand how different powerplants work. His attention to detail is truly impressive and he has created everything from twin rotor engines to fully working RC car brake discs and even created his own supercharger.

Today I want to talk about his modified Toyan v8 remote control car project, 1/7 scale, 28cc. This is a time-consuming and complicated process. To better control the little car, he designed a manual clutch. He also installed a homemade three-speed manual transmission, with plans to upgrade the centrifugal clutch. It turns out, whether it's a Dodge Challenger R/T Scat Pack or a 1/5th scale RC car, naturally aspirated V8s are great no matter their size.

Using a 5-axis bench mill, he began creating complex parts. After upgrading the clutch, he realized the design could be further improved and set out to create a manual cone clutch. Using plastic and metal, he cuts first the female cone and then the male cone. Then there are clutch bushings, clutch forks and clutch levers. He then produced clutch bearings, combined them with propshafts and transmissions, and began testing them.


It's all driven with a little dial on his remote. He starts the engine, then tests the clutch shift forward and backward, as well as engaging a higher gear. The vehicle was happy in 2WD but struggled in 4WD until he said he made some adjustments to the system.

He went on to mention that the video took a long time to create as he went through a few clutch designs until it was perfect. Next up on the agenda are finishing the electronics, strengthening the chassis, adding brakes and then building the exhaust system. Just watch the video and you'll be excited to see the final product; even at such a tiny scale, the V8 actually sounds great, and it's always great to see how impressive an RC car can really be.
