Mnewton. I think the Dagling was used for the first time whilst I was there. Fitted with an ASI and an altimeter it was winched to about 900ft. S/Ldr Topsfield flew it, and he did the same at a Battle if Britain display. As you say, it flew like a brick, and surprised the hell out of an Auster that was on short finals, as the Dagling appeared in front on a base leg. Happy days!!.
