Hi Tony,
Two actuators have been specified over the years. Early Tri-gears used
"Motion Systems" type 85615, but once the company discovered they were
being used in aircraft, declined to supply any more. They are still
being manufactured and design data can be found here:
http://www.actuator.com/products/product/linear-actuator-85615-85616/
Europa then sourced its actuators from the German "Baumeister" company:
http://www.baumeister-balingen.de/english.htm
The model you're interested in is the 120se - navigate to
>Products>Actuators>Actuator Series 120>Actuator 120SE" where you'll
find a data sheet with the loads you want.
Speed of operation is important when choosing an actuator. The earlier
Motion Systems actuators were much faster - which could be a benefit in
getting the flaps deployed quickly, though there were isolated reports
of the carbon brush assemblies failing.
Hope this helps.

Bud, thanks for your offer. I already tried to attach photos but will try again
later. I removed the mentioned sealing again, since it obviously made the situation
worse.
Again, in flight the setup worked perfect under all conditions-I even didn't came
close to CHT-limits when climbing FL200 in summer without a level off.
CHT reading should also be correct since I once shut down at 118C and could hear
the coolant boiling a little bit.

Try Traffords 01525 717185.
They can provide endorsements for items not usually covered by standard Travel
Insurance. I used them when I used to fly when on holiday in Portugal.

TonyI believe the load on the flap operating lever is very low, the flap pi
vots are on the lift vector line, (not sure if i'm explaining this right?)
so the load changes very little throughout the range of movement of the fla
p. Flying a well adjusted monowheel one notices that the flap can be placed
anywhere in it's range and left floating. It won't move. The bungy is ther
e to compensate for the weight of the undercarriage.

Cheers.
Like I said though, I don't want to put anyone out too much, or steal their
time.

About 3 years ago my aircraft got converted from mono to tri-gear and I elected
to keep things simple by retaining the lever for manual flap operation. No electric
motor has been added, to keep weight down.
I agree that the loads involved in moving the flaps seem reasonably constant throughout
the travel of the lever, perhaps becoming slightly heavier towards the
fully extended position. Just a subjective opinion.
