I am looking for a transmitter that gives me the most steering wheel rotation angles (left and right) of the transmitter itself (not the steering wheel on the car), anyone has any suggestions?

I think a lot of transmitter wheel gives around 30 degree on each side, hoping to find something close to 90 degree on each side?

Thank you!

Simply install a larger diameter steering wheel on the transmitter

If you are looking for something for drifting, otherwise why anyone would want a wheel with more throw than it already has, check out this mod instead.

Thanks to both bill_delong and Beaver_XT, very good suggestion and that mod was cool, but probably overkilled for me. yeah, just looking for some drifting fun with a mini-z. will look into a bigger diameter steering wheel.

There is a guy at the track in my area who used one of these adapters here to mount a 1/10 4WD buggy front wheel on his Tx which is significantly larger in diameter than most stock steering wheels:

Thanks! The link didn't work but when I search wheel adapter on that site a lot of results came up. Thanks again.
