Introducing the new Graupner X-4S 2-channel 8-function radio transmitter for cars, trucks and crawlers. Based on the tried and true 2.4GHz signal, it jumps between up to 35 frequencies by using optimized two-way HoTT technology, maintaining great signal lock with zero latency from ranges near and far. Plus, its interference rejection technology prevents local competitor interference. Dual rate and trim function knobs are easily accessed by feel without having to look away from your vehicle. Touch sensitive buttons allow function activation while accelerating and braking.


The X-4S is ergonomically and technically modern for ambitious and professional RC car and speedboat drivers. With its consistent technical optimization, this device offers an advanced operating and functional comfort in its class.

Can be set for left handed drivers.
Being able to adapt the steering wheel to the left side was the winner for me. Works okay, but the steering is a little sensitive.

very nice,no frills.
went from sanwa mx4 to graupner I wanted to try pistol with drop down wheel.The receiver is smaller than my sanwa 92524 which is a micro receiver,that's a bonus!I run a 1/10 tc on crc high bite black carpet,I have no problems with interference/noticed no loss or difference in throttle steering,keep in mind though this is bare bones receiver for intermediate driver at best(no fine tuning options or digital display).OVERALL I LOVE IT,IT FEELS GOOD AND ALOT BETTER THAN SANWA CONTROL!I am very happy will definitely step up a model next time and would definitely purchase more graupner products(excellent customer service so far)thankyou!

Recieved radio, steering wheel felt funny. Got matched to my car, steering wouldn't work properly. Called and was issued new steering assembly immediately. Awesome customer service. Bought it to switch to left. Re instructions were pretty clear except about the sticker on the front. I just cut through it. Seems to be an ok radio as I haven't gotten to test any responses yet. Does have alot of adjustability to make comfortable for just about anyone. Price is also a great point as there aren't very many left hand radio out there.
