I purchased this transmitter in the hopes of using two radio-controlled cars simultaneously or controlling multiple cars with a single transmitter in March 2025, but I never had the opportunity, so I've been storing it. I've used it a few times, setting it up on one car. Since I have another transmitter, I don't plan to use this one, so I'm putting it up for sale. I'd like to pass it on to someone who can make good use of it. I look forward to hearing from anyone interested.
