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 Quickboost provides replacement wingtip pitot tubes. The AMK kit molds the two pitot tubes integral with the wing upper surfaces. The picture of my completed review model shows the kit pitot tubes. They appear somewhat oversized and were fragile. I had to be very careful while masking and painting. I have read a couple of build reviews of the 1/48 scale L-29 from AMK and both of these replaced the pitot tubes with wire or stretched sprue.
