I have used the 1/16 Aber kit a lot of the parts are fiddly and very small the driver/radio hatch detail will take you more than a day to compete per hatch a lot of the parts act as molds where you have to fill them then drill holes the best parts of the kit are the exhaust and side fenders however front and rear mud guards are a lot of work and totally unsuitable to RC these parts will get riped off in no time, the kit will more than double the build time of your Tiger though the detail it will add will be very good, you will require various small pliers/tweezers and an etch mate to build this kit if you have no previous experience with PE kits this one may be best left alone.
