Ciao Cleve,
The picture of the switch.
The screw allows to adjust the motor travel.
The accident with Bruno had no official response.
The common convinction is the flight in a day with a very strong wind (more than 40 Kts). More than one on the airfield advised them against to fly that day.
The intention to show the handling characteristic of the plane to a possible buyer, at low speed, led the two pilot, both without a great experience, to fly downwind at very low airspeed.
The inexperience of the co-pilot on that machine, the will to sell the plane , the low height, the sum of all, made the rest.
Ciao
Luigi

Oggetto: RE: Lightning-List: Flap setting-adjusting max flap travel?
Thanks Luigi, A picture would be great, the rods are very close to the central beam bracings so I’d like to hold the actuator back a small amount.
Certainly 38 degrees (I think it was) of flap needs using with care and knowledge of the implications. Pitch up on go around was horrible and the stick didn’t do much to the pitch.
We must remember the accident with Bruno, was that ever explained by the investigation?
Regards, Clive

Thank you , Clive.
More or less the amount I calculate to be correct.
Yesterday I checked it and should be 11 degrees.The full travel is around 40 degrees. I believe 20/22 degrees is more than enough to land safely
In case of go-around, with 40 of flap, should be very dangerous to forget the flap down (or in case of failure to retract) because the stabilizer may suffer the shadow of the wing and became inoperative. Situation not very good.
For the limit of travel, I opened a similar actuator and, inside, there are two screws which allow to adjust the travel of the motor moving the switches .
Tomorrow I'll try to find the old actuator and take a picture.
Ciao,
Luigi

Oggetto: RE: Flap setting-adjusting max flap travel?
Hi Luigi, on My Esqual (great big flap model) I use 10 degrees for take-off, maybe a little less.
A question: Is there a way of limiting the maximum flap travel electrically? Within the motor unit? Anyone had one apart?
Thanks, Clive

Subject: Flap setting
Hello everybody,
on the Esqual POH I found different instructions about the setting of flap for take-off.
If the setting for landing is well described from Clive and others, with all the problems arising with the trim, setting the flap at full travel, is there any info
concerning the approximate setting for take-off ?
The Esqual manual says "between 20 and 30 degrees". I believe this is not right.
Any one experienced different setting ? With the behaviour of the plane in this condition.
Thanks
Luigi

Hi Luigi, this is a different type to mine I think, see attached. The picture was taken in Moia in 2002.
I’ll need to take it off to get into it on my aircraft.
Looks very compact and it may not be possible to tweak it. I could of course fit and exterior switch which maybe the easier way in the long run.
Thanks for the picture, Regards, Clive
