Not quite enough wind at Scarborough but seemed viable.
Flown on Blackheath 14th July 2019, light wind but all seemed fine.
1st March 2020 attempt in stronger breeze 15mph gusting upwards failed due to broken spar.
Follow-up on 8th March 2020 was successful in similar conditions using ground anchor for bridle preparation and in flight.
End cap metal components are rusty and need to be replaced with stainless steel as at 02/08/2021.

Repair to top centre bridle attachment point
After the successful flight on March 8th 2020 a small repair was identified and now fixed... Saturday 4th July 2020

Careful preparation and a long launch worked well today.
The kite was sometimes 'nailed' but occasionally a bit skittish!
Some bowing of the cross spars is evident in stronger gusts. An RSS Rev breeze.
The hand held annometer showed 13-15mph and the kite was pulling hard, just possible to hand hold for a short time. We walked the line down, disconnected the kite and a few steps forward it touched down gently, then it was turned on the ground and staked at the top edge.

An approaching thundery shower closed proceedings!

There was a moment of anxiety getting it out of the bag as the elements did not fall free, seeming to be inextricably tangled. Fortunately appearances were deceptive and the 'unfolding' resolved the apparent tangle leaving the bridle lines free to the comb. In windy conditions the windward 'edge' needs to be secured at all times. I had set a ground anchor at almost right angles to the kite and the wind direction. Once the spars were set the kite was held up on its edge allowing the bridle to be combed out completely. The kite was then held flat on the ground with a 'pin' through the top centre join point while the tails were attached.
At this point I made a 'mistake' and as a result a spar was broken and no flight was possible. In lifting and turning the sail in 'high wind' the bridle needs to be secured statically, that is, to a ground anchor.
Wrapping the kite was done with the 'pin' through the top centre; removing the horizontal spars first but leaving the centre of the top one in place until the verticals were split in two and the lower sails folded over. The loose bridle lines were wound around the sails up to the comb and remaining plaited bridle lines. The kite was put in the bag followed by the plaited bridle and finally the loose spars.
Fortunately, fixing the kite was easy, slide the spars out, check the damage and slide a new spar in...

We did not get a sustained flight on this occasion.
