RE: CARF F4U-1 Corsair build thread
Instructions say the CG is 1/2" in front of the main spar "when viewed from the top". This is important to note because the spar is canted forward slightly. Not sure yet how critical this is on this plane, but we are setting it up per instructions for the maiden at least. No mention is made of whether want the gear up or down for this, but to be safe, we had the gear up. The Moki 250 with it's ignition is heavy, so it helps with the process. As 2/3 of the tank is ahead of the CG, and the gear is also fairly heavy, with fuel and the gear down, she will be safely nose heavy.
