Hi Rod,
Sorry for the delay in answering your request.
Go to the upper right corner of this page and you will see the word "search", in the box to the left of the word search type: T-REX BUILD then click on the word "search".
You will see several build threads that will address any questions you may have. The electric build thread is comprehensive, the others may help too.
If you can't find the answers to your questions, please feel free to make another post and I will find an answer for you.
Regards,
Rudy Taube
