Oh, you're replying to my question on the previous page asking why he wants to fly 500ft circuits !
I was hoping that planet47 would tell us why he wants to fly low circuits where the terrain is unsuitable.
She (the pilot) doesn't necessarily want to fly 500ft circuits and I have flown 1000ft circuits in the the 'silver. The slowsilver's net weight is 126kg and its upper limit is around 250kg. It is extremly susceptible to getting blown around and unless you've flown one of these, I don't think you could understand just how susceptible it is. A 10 knot wind is about the upper limit. Yes indeed I have found it pays to keep a 500ft circuit tighter than a 1000ft circuit and there have been times that I found the lower circuit level to be less turbulent particularly when the wind is from the northwest.
Most of the land surrounding the tarmac and the grass strip is not necessarily conducive to emergency landings whether you fly 1000ft circuits or 500ft circuits. To the south is the river delta, bridges, an island dotted with power poles; not far to the east from the grass strip is a town area and dairy type farms and more power poles; to the north off the tarmac a few paddocks and then the trees start for probably about 7 miles; and to the west well that is just tiger country, with two small clearings, more power poles, a cemetery (and I don't feel like flying in there) and more waterways. I refuse to take off to the west cause there is no real option in the event of an emergency and I would probably end up parking it in the cemetery.
The slowsilver is in the experimental category. At last count I have done around 30 hours in this particular machine and have done around 240 hours all up. Thanks to M61A1 for the advice - it is appreciated +++.
