The Hobby craft 109s actually fit rather well, it's just the radiator under the cowling is not quite right/half missing. But if you can get past that, it's actually nice.
Oh FYI, the horizontal stab struts are slightly too long, so I just filled in the locating hole and filed off the pin and glued it flush.
Thanks for the warning.
I'm guessing you mean the oil cooler under the nose? It also needs the 'splitter plate' in the forward aperture. Also, I think the tail-plane leading edge 'sweep' might be slightly off, but acceptable, but I'd have to check this against scale plans.
As these kits will be used as part of a collection of 28 models in total, for the BoB 'Hardest Days', I'm not too bothered about slight inaccuracies, as any such would have to be inspected really closely, which isn't going to happen once they're arranged in the cabinet.
