1. Where can I find English version of the software?
The manufacture of Manoi, Kyosho, does not provide any english support... Therefore, you have to look online and see if there is any english version is uploaded by 3rd party like us... We do have "OLDER" version of english software, which is version 3 (created in 2006)... the current version provided by Kyosho is version 4. I haven't had any problem using it before, so if you are fine with using older version... use ours.
Also, if you want to use version 4, please look at this page. They have a English patch for HTH ver4.
