4.5 GREAT SCOTT .............2015 hover conversion 5buckproductions | 29/10/2009 | See all 5buckproductions's reviews (9) This is 1/15th scale not 1/18th as stated , diecast in plastic . a must have for any bttf fan .There are a few flaws . first off the exhast pipe is upside down , the paint job is a bit iffy ( marks here and there ), the decals are badly placed . there are NO dmc logos on the grill and wheels . The hover conversion slide switch seems a bit delicate . lastly the sound is a little too loud for the internal speaker to handle .now for the possitives .IT is awesome to look at and dwarfs the sunstar ones ( i have all 5 of those ) . there are also lights in the dashboard , time circuits , flux capacitor , head lights , brake lights , rear vents .there are 11 light and sound cycles by pressing the button . the doors and bonnet open . with some good detailed parts .i couldnt wait for the u.k release so got hold of a few from the U.S ( well i am a bit of a Fan of BTTF )my rating is 90% so not exactly the 5 starsbut customising these will be fun (p.c usb controlled ) .
