Im sure there are more than a few 501X owners that already know these 2 mods but for anyone else I simply have to share this with you.
Possibly the biggest weakness for the 501X for any racers that use these cars on dusty tracks would be the rediculouly open diff centres.Without a doubt keeping dust from the diff bearings and plates is a problem and I know Tamiya have some decals for the on road car which can be used for this but I just made a set myself from some old decal sheets.Its almost a no brainer,the decal sticks to the side of the diff belt pulley and Ive gone as far as to trim the centre just enough to slip over the out drives.On the inside of the decal I also trim the backer paper and press it back onto the decal so to stop the decal from sticking to the outdrive's outer face.Let me tell you this works like a charm.Since running this at my track I recently pulled both diffs down and there was very minimal dirt inside.
The second little mod was to fill the arrow and dot in the adjusters with white paint.The last time I tried an adjustment at the track I wish I had have painted these sooner.
