Very sweet to see another RC rotary car. I drive a couple 1:1 RX7s myself and if it didn't cost so much to maintain, I would have liked to start on a rotary RC project too.

Info on the flywheel, fan, clutch, and gears?? Thats the only part I'm curious about because that is probably the hardest part to make it compatible in a car chassis.

How ironic. The rotary engine is very compact in the real car world yet in the RC world it is humongous. . I guess everthing in real cars is the reverse in RC.

Nice work on the car though. Thats quite some project. Especially the gear reduction to make it happen in the rotary's rpm range. Again opposite in RC because it has more torque and less rpms than a nitro piston motor but the real life version is exactly the opposite.

Wow, its a "wanker" engine on a mtx-3.

How are the seals on a small engine like that?

Its not really opposite. The OS Wankel is after all a .30 vs the normal .12 engine setup.

Those are some nice pics. I'm a rotary man myself and retired street racer and something like this is appreciated by a true rotary fan. I was gonna build a rotary r/c drag car about three years ago but it never happened. Hopefully you can build a drag version of your set up. Keep in touch. THUMBS UP TO YOU!!!
