G-AOTF was one of the ag-chippys. Shown here in about 1985 with a 160 hp Lycoming in a fetching air defence grey colour scheme - which when you think about it has to be the worst colour to paint a tug. IIRC, she was a Mk23 which used a raised rear cockpit as the flying position, had a space for a hopper where the front seat was, and I think she had leading edge slots as well. A bit lighter than normal Chippys, she didn't suffer much performance loss with her 'uglification'. Except that with a Lycoming, she wasn't allowed to spin or aerobat under CAA rules, as she was modified as a glider tug and such certification wasn't deemed necessary.
