Buh, riguardo il cg:
Now to get the airplane ready for flight, there is AN IMPORTANT MODIFICATION. Instead of the CG specified in the Instruction Manual at step 99, set the CG at 1-1/4 to 1-1/2 back from the front of the landing gear door opening. For the first test flight, set the CG at 1" and adjust rearward later.
Preso da qua, dove ci sono molte istruzioni:
