My brother and I went to the hobby shop yesterday. Sort of a Christmas shopping run. They had both Sky Raiders, and I thought about this thread, but they did not have an LA Racer. I do not know if they'd be willing to help, but you could call Airborne Models (925-371-0922) and ask if they have the dimensions of the cowl. I've never seen an LA Racer at the field or at the hobby shop.
