I fly at Cubair, have done for about 10 years. Do it because they are a good friendly bunch, who genuinely want people to learn and enjoy themselves. I'm more of a friend than a customer.
I have had a PPL a long long time and fly their PA-28. I used to fly the DA40-180 and will again when it's available. The Cub is also an option but one I've never followed. I've only flown a DA-20 once, just have a preference for the PA-28 as most of my time is on various models of Cherokee/Warrior/Archer and 172s.
I don't have an issue with the wet boggy grass because there are hard taxiways and a slightly challenging piece of taxiway known as RWY 25/08 (look in the AIP or on the Redhill Aerodrome web site) used when the grass is too wet and soft. It generally works fine but being narrow is a bit cross wind limited. Normal crap visibility is more of a constraint than the soft airfield.
I last flew in December and am just waiting for Covid to allow me to fly again. I am quite happy there.
