When so many of us started out with hollow logs as a first or second
attempt at flying, I found how a simple mistake can just ruin our
perception of certain brands of engines.
I recently acquired this cool little Scientific Zig Zag which most likely
has never flown or flown very little. Either way, I found two problems
that can be attributed to this particular plane.
First the stock fabric hinges were completely doped over which would
make the control stiff and almost nonexistant.
Second, the tank was mounted upside down and at a strange angle locating
the pick up tube to the inside of the circle. Of course this would
severely restrict engine runs, giving the impression there might
be an engine problem.
The engine in this case is an AMF Wen Mac Mark XI 049 and could have been
the brunt of many an ugly comment!
Since the tank was buried in the fuse and unseen, one could only assume
that it had been installed correctly.
The only reason I know it wasn't is because the plane was in need of
repair when I purchased it and the wing had been broken from the fuse.
I have to wonder how many little slip ups were made and never found out or
corrected contributing to the ill will towards engine brands, fuel or the
hobby in general!
