Flew the Jp3/5 and Strikie,
Spinning the 3 as memory serves the tips had to be less than half full and balanced
Spinning the strikie used to scare the sh#t out of me, armour plating affected the B/A ratio, VERY nearly had to punch out of one that did not want to recover. Was briefing the ejection when it recovered with a final attempt at centralising controls and praying.
Also seem to recall the party line on the 5 being that the strakes made the spin less oscilliatary[sp?]
