Greetings and Salutations... Looking over the weight and balance information I have from Bartoe it indicates a CG range of 18inches to 21.6 inches. The owner of a sister ship has an unsigned letter in his package which came from Bartoe and it states the forward CG limit for all serial numbers should be 17inches not 18inches as previously stated. Has anyone else run across this 17 inch forward limit? I would like to use it but I am cautious of unsigned calculations. Thanks in advance. Tom
