Foxmoth,
maybe for sensible practicing initially, hell in the uas we used to clamber up to 10,000ft for 3 turn spins... but its no good for competitions...
I saw nothing to say this was a competition - both comp and display you are either solo or with someone even more experienced than you are, NOT flying someone inexperienced - even solo I would not be recovering as low as 700' unless I was working up for a display or comp.
