I don't own a TT-01, but here is a link to Tamiya's RC Manual website. You will be able to download the manual you need for your specific model of TT-01.
You may not be aware, but there is also a thread dedicated to the TT-01 here on RCTECH.net. Here is a link to that thread (TT-01 Forum
). Someone there should be able to better answer your question.
Hope this info helps.
