One thing concerning me here. If you have not flown your aircraft yet, then you might consider the words in the manual. It is suggested that the 7/16inch is established as a safe place to initiate first flight as this is purposefully establishing a slight nose heavy situation as apposed to a nose high on lift off and possible stall. You can make adjustments after first flight to improve trim. Everyones Wt. & Balance will be different.
