Most of the speed controls I have seen recently can all be set up without using a computer. You calibrate them with your receiver for full speed, neutral, and reverse. Then you can go through the programming with the radio using either full forward or reverse as a yes or no answer to the esc. The only things that are usually not adjusted by the radio are things like timing and custom cut off levels. As far as what to get, for what you have said it would be used for, I would suggest a Castle Mamba Max pro or maybe even a Sidewinder v3. Although both can be adjusted with a computer, they can also be adjusted with your radio.
