After our first flight it was decided we had to fix the tail wheel lock and replace the battery before further flying & starting attempts. Eventually the tail wheel lock issue was resolved and with the ARC due soon G-EJBI headed off to Little Snoring for a discussion with the resident maintenance company. The guys were very pleasant but decided, probably quite rightly, it was not their type of plane and although they did not want to leave us in the lurch I was advised that any work they undertook would be expensive. We left Little Snoring a little unsure how to proceed.
