For general information on a particular model, possibly the best way to gain the answers you need, is to ask a question in one of the build threads on RCGroups, or post a new thread there (you will need to register with RCGroups to enable you to post, but its free, and highly recommended. Chances are that Peter will be along anyway to answer.
