after losing one of my drive cups from the centre shaft, i went to my lhs to get another 1 or 2. he had none in but could order them, but they take about 2-3 weeks to get them in. i scanned the shelves and found a pair of kyosho drive cups that will work fine. the part number is AE57 and there is also a "200" on the pack - i saw some the same with a "300" on there and they were twice the price.

the ones i got were £2.50 for a pair, cheaper than the cen bits, but more importantly - he had them in stock!

just thought id let u know....
