I owned one for a while (AA1 B modified)
There are sight tubes in the wing roots so you can see exactly how much fuel you have, so no problem with not being able to dip the tanks. But they only have small tanks so limited in range/endurance.
They fly nicely, like a little fighter with those short wings, but I had a few bum clenching moments on takeoff with the long ground roll. Be careful on sideways sloping runways because the castoring nosewheel and small rudder means you have to drag the brakes on one side a bit until the speed builds up lengthening the takeoff roll even further. I had to break right on takeoff from Popham when taking off towards the trees once for this reason, raising the heart rate a bit.
I also had a few moments at Sywell where I was based when the fence at the end of the 750m grass runway was getting very close before liftoff on low wind days.
But great to fly once in the air.
