No it doesn`t. This is always a criticism levelled at planes with a higher
than usual thrust line. In practice it makes no difference that your normal
flying instincts can`t cope with automatically. If you are pushing your sp
eed envelope from high to low, say when you switch from cruise to landing a
pproach speed you may have to re trim but so what, you will have to retrim
as the flaps come down anyway. Good luck. Pat

Thank you Larry, I will try that before I start making any changes or modif
ications or work-arounds. I was indeed trying to keep the engine as low as
possible, with the "gearbox low" engine configuration.
It was already obvious to this old washed up model airplane builder that th
e thrust line being too high will cause problems with performance and handl
ing ! But it is good to hear that my own instinct matched the actual real-w
orld experience of Kolb flyers.
I tried to look up anything in the archives that addressed this problem, an
d it seems thata a David Bigelow in hawaii had this same concern on his Fir
estar.

Mine
will clear using the same mounting as for a 503. You just
have to hold the ailerons at a certain attitude when you
fold, and that is only on the right side. There are
different exhaust configurations available, none that I felt
moved to explore. You would not like mounting the engine
higher than absolutely necessary. Larry

Pat/All
One of my early reduction drive VW configurations I had a rather high
thrust line. Flying solo I had to feed in power slowly so that I wouldn't
nose over. The first time I flew with a passenger I found I had to reduce
power to keep the thrust from overpowering my elevator on takeoff. With a
passenger at low air speeds with full power and full up elevator it would
not pitch up. At higher speeds it was just OK. I never.... attempted a go
around with a passenger. Actually I never flew with a passenger again in
that configuration. I switched fairly quick to the new VW engine mount that
significantly lowered the engine. In this case the high trust line was down
right dangerous.

Richard, The story, as I remember Travis telling it anyway, is that the
last owner before it reached me had the guys in the Kolb shop mount the 582
on stilts for just the reason you ascribed to it. They didn't want to do it
but the owner seemed, by the way he did everything else, to have no clue
about what such would do to the prop inflow and overall drag. I never flew
it that way. I moved the engine backward to clear the starter, changed the
Rotax twin radiators to a single one from a Honda Magnum motorcycle, and
dumped the intake silencer.
