Slash Medusa owners??

[Jeremy1976]

The shaft on the Medusa 36-50-3300 is shorter than the stock titan. So with that being said I could not put the pinion on the same way as on the titan. If I did with the set screw facing out it would not make contact with the shaft to lock/seat it to the shaft. So I had to spin it around with the set screw facing inside. My issue is the gear part of the pinion then is not lined up well with the spur gear. Only about 3/4 of the width of the gears is in contact with the spur. Anyone run it like this or am I missing something? Thanks
