If there is anything you'd like to know specifically let me know, Im an ex cabair engineer and worked on the 6 Diesel PA28's Daily.
I'm now based in Bournemouth and have just finished rebuilding and flying G-OOFT, G-CETD's engine arrived yesterday as did G-CETE they will be in the sky again soon.
I've been working on the diesels for over 6 years now in the PA28's and DA40's mainly, but the odd 172 aswell. I also did the Thielert course in Germany, so feel free to ask any questions
Oh I'm 110hr PPL too, over 100 of those hours on diesels
