The L-29 Delfin was a jet-powered trainer airplane that was designed by the Aero Company of Czechoslovakia. An excellent kit of the Delfin has recently been released in 1/72 scale by AMK. Although this kit, in my opinion, is very good, our friends at Aires/Quickboost have found some areas where the accuracy of various parts can be improved.
This set from Aires provides replacements for the kit elevator, rudder, and flaps. The four flap parts provide additional surface detail but mainly provide very sharp trailing edges. The flap parts also have some added detail molded into the sides of the flap parts. These parts must be carefully removed from their molding sprues because of their fine mounting struts.
The new elevator offers a slight improvement over the kit part. Surface detail is about the same but the Aires part has finer elevator tip counterbalances and of course, the trailing edges are sharp.
