If you cannot find anyone who can help you in Japan, try looking in the different forums here on RCU. Abufletcher lives in Japan, and is a good builder. Once you get to the UK, see if you can find another RCU member, called, Oldgit (AKA John Livingston). The builders won't come and find you, so you have to find them. There are hundreds of RCU members who will be glad to help you learn. If you find a thread that is applicable to the plane that you want to fly, then join in the conversation, and let them know that you are a newbie, and need, (and most importantly), want help.
