Here is a link to an Instructables manual detailing how to modify a Best Choice Products Jeep. The manual was written by FIRST Robotics Team 1939 and describes how to convert the accelerator from a pedal to a button.
Do you think it would be possible to use your Jeep manual to modify the Aksum 12 volt Jeep? We are hoping to use the Aksum jeep, but really need to be able to follow a manual. Any suggestions? Thank you so much!
