I certainly do have an IN NEO. Ive known Glen for 15 years personally and I always talk to the guys whenever I go to Goodwood which is quite often at the moment.
You are right they will need engineering, I am not sure what arrangements thay have made at the moment, must admit I forgot to ask that. I was talking to a young guy in the hangar who worked for the previous engineering Co, he was saying that HeliAir maintain Elites aircraft that are based at Waltham. I also heard that Aeromaritime were interested in Goodwood, this came from a different source however and I am not sure how reliable that source is.
If I find out more I will let you know.
