I went in non-radio on Friday in the FRED. I phoned for ppr and joined the northside 'racetrack' for the grass on downwind as briefed. The system seemed to be working well. My main problem was that I was marshalled to the southside for parking. This involved a long taxi across the field - lot of it on hard surfaces. The FRED has a tailskid and this was an obvious problem (sparks everwhere). It took over half an hour (following a vehicle) to taxi back to the grass runway later in the day. - Very poor!!
Apart from that, a very nice event.. But I prefer Cranfield.
