Hello, I have 2 of the Matchbox kits as well as 2 of the Revell kits. The Revell kit is better in that the plastic is better quality. I've got 5 B-24 D kits as well as Eduard PE sets for them. I will build them as PB4Y-1's and later-1's The Squadron vac form canopies are a nice addition. Cobra Company makes replacement resin parts that will fit the Matchbox & Revell kits. You will definitely need metal landing gear as well as lead for weighting the nose. I've got 2 of the Pavla Liberator GR Mk V kits. Quickboost makes a nice assortment of add on parts. CMK makes a nice set ofcontrol surface. Airwaves makes a nice set of PE for the flaps. This might prove to be an expense, but it beats trying to scratch build everything.
