Well done for not harming yourself and providing an opportunity for everyone to learn.
Engine off
Spot landing practice is the answer.
It vexes me that I always forget to do this. when on a usual flying day place a big marker in yr field cut your engine and from height try and land exactly in that spot.
I believe the sharpish S-bends on approach will loose you height fast if needed, still allowing you to land on a spot.
you did well to remember the trimmers that makes a big difference, 300 foot is not very long to establish a circuit and landing.
but I just want to relay a small story about bikers fixated on corners to illustrate the problem.
Scott and Justin two GSXR rider friends of mine on a trackday / tour of France, they were following a bird on a bike quite close going round a corner.
The lady in question went straight on through a farmers field on the other side of the road, as she could not make the corner at about 50 mph.
swiftly followed by Scott and Justin, straight on top of her.
rather than go round the corner they just followed her crash, fixated on her bottom. way to go!
quite funny I thought, especially as they had it on video!!
go well
