RE: Building the Flea-Fly
The fuel tank was just shoved in for the size check. I did note in reading the Fle Fly article that the CG is at 40 percent and "you may have to add weight to the tail". Now that sounds good as it may mean the battery can come out of that rather cluttered compartment. I am not too happy at a 40 percent starting point though so I may start with 35 percent and move it back if its OK.
