Hello I tend to copy my old kits rather then build them now. Modern kits are generally easy to build when lazer cut and if the balsa is light, make life easier. What I like about old kits is they are like time capsules , the neat old plans , alloy cowls , wooden wheels, old dried up glue bottles/tubes and interesting instructions and hopefully amusing illustrations that make them fun. Bit like old lapped steel baffle engines , interesting but not always the best choice today unless you want the nostalgia element or period correct feel.
Regards Gerald
