What was your best.

It was a Tamiya 1/12 Yamaha YZR500 Grand Prix bike (a photo graces the pages of Rongeorge website - it's yellow with no fairing on it) - It was one of my first attempts at serious scratchbuilding - I replaced all the tubing/wires/piping with more "in scale" wire, scratchbuilt the backs of all the instruments with appropriate cables and fittings, cut off the fork legs and replaced them with 1/8" welding rod (polished), built new throttle linkages and carb piping, made brackets and then springs for all the exhaust pipes (two for each pipe) and followed it up with probably the most tidy paint job I've ever done. It won me the best bike of show at one of the yearly Melbourne model contests.
Regrettably, an enthusiast made me an offer I couldn't refuse and I sold it to him for $500 two years ago. I still miss that model. At least Ii still have the trophy.

it's a personal thing mind you......but, it's a tie between a 1/72 B-24D (the only one i've ever been commissioned to do) for a friend's father for his 70th birthday.........and a the Monogram "B" Mustang backdated to an "A".
i touched a space in time with the Liberator build as my friend's Dad had not seen that plane since he was in his mid 20's when he parked it somewhere in China after his 25th or so mission and walked away from the CBI.
the mustang was a lot of scratch building, chopping and cutting which taught me new skills.......more patience and gave me confidence to try anything....at least once.
i wish i had a scanner to share the in work and finished pics......but, that'll be soon enough.......

The Italieri Panzerbefelshwagen I. A great winter project with PE and Modelkasten tracks, and my first serious attempt at weathering with oils.

I think it is going to be the one I am doing now. A mostly scratchbuilt fire truck. Everything I am doing on it is a learning process since it is the first time I have attempted to build like this.

The next I hope.

Hasegawa 1/32 me 262 with scratchbuilt cockpit (almost all of it, replaced seat stick panel and added a good gunsight made from about 20 pieces of fine styrene and stretched sprue) scratchbuilt landing gear bays (old ones were just holes, there are at least 200 pieces in the main gear bays) scratchbuilt landing gear legs (all aluminum) scratchbuilt lowered flaps ailerons slats and elevators (that was the hardest part) but I botched the canopy with glue smears
