Define best kits ?? if you mean what kits one actually enjoyed and left a great impression on one ...well i was born in 1952 and began modelling around 1959, these are 'my' best as far i i can remember......
I began making balsa kits with my uncle...encouraged by him and my grandparents who thought it a great thing to do and they continued to encourage me in modelling until they eventually passed, i owe a great deal to them, anyway ..plastic hmmmm
Airfix 1/72 R.E 8 loved it to bits and kept the bag header card for years , 1/600 Hood it had a family connection and i must have built at least five or six . oh and 1/600 Queen Elizabeth then ,Aurora space station and moon rocket, Airfix 1/72 B17 'Bit of Lace' i remember making the Airfix H.P.Hampden making the props spin by opening the quarter panel window in my uncles black Vanguard sedan i remember that day vividly,
Revell Monogram 1/48 Avenger and Corsair the folding wings and undercarriage were amazing to me then, i remember Dad helping me one summer evening with a Monogram 1/48 Piper Tri Pacer and encouraging me to begin painting my models
Later the Airfix Meteor F1 because i love Meteors
Then i had a break whilst the Army, work and marriage slowed me down
Then around 1979 Testors put out a 1/48 F18 and i built that along with a few Matchbox kits, 1/72 Privateer 1/32 Puma and i was back, scales were confusing when i rejoined the game
Then in the late eighties early nineties ? i built 30 odd 1/72 Fujimi /Hasegawa F4's of all variants and drove the blokes at my local club nuts every month bringing another couple...poor sods
Then i changed to 1/48 , found resin and limited run stuff the stash grew as did my need/greed !
Now i am swamped by avalanche's of extreme goodness and struggle to keep my lust under some sort of control
Modern day i cant answer as i love it all
Recently i bought from ebay... a few bagged Airfix kits for display in my study, pride of place is my Airfix RE8
Yep the ancient RE8 gets my heartfelt vote
