Europa-List: When to retract the flaps?

Not sure what led you to believe we have a Trigear. G-LABS is one of the 
original Classic monos - Kit 49.

In fact we have Ivan Shaws original Rotax 912 engine out of G-YURO. You 
could call it son of YURO !!!

As regards the flaps question I totally agree that you need to get rid of as 
much drag as possible as soon as possible. However a full retraction of the 
flaps will cause the aircraft to sink (anything up to 100ft). I was warned 
by a very experienced pilot that this was not a clever thing to do 
especially at 200ft.

The other problem with retracting early (especially if you compromise and 
only half retract) is that should the engine stop,  you are likely to forget 
you retracted and set yourself up for  wheels up landing (or crash if 
applicable).

I would say the safest height you should raise the gear is about 300ft and 
in any event I would rather concentrate on flying the plane and seeing where 
we are going. As G-LABS is somewhat underpowered I have to keep the nose 
well down to build up speed (65kts) before commencing the climb.

I always assume there is a chance the engine could stop and on a nil wind 
day it is not uncommon to cross the airfield boundary at 300ft. I would 
NEVER consider turning back under such circumstances. As soon as the 
aircraft is airborne and manouverable I point it at the nearest open space/ 
field (subject to where the gliders are launching and the location of the 
winch).
