yes brian they work very well and simple to adjust, not a huge amount to show , been cracking on with the filler , one louver was badly out of shape so i had to repair that, also i cut the tunnel out of the scrap s3 appia to put into the ardea, by no meens a simple task as i'm using a floor change box and the tunnel is totally different but closer than the ardea tunnel, i've started making the front engine mounts up and getting the engine and box at the correct height and angle, plenty more to do yet, looks like i'm going to have to make a special exhaust manifold to clear the bulkhead and modify the rhs inner wing to clear the weber manifold
