Ofna Hyper ST Conversion!

Finnster is getting one - They are actually a little harder...

There is no big seal just a small o-ring which was a little bit of a pain to get it to stay on... not a biggie though

The spider is a different animal - unlike a normal diff the body is in multiple parts with long screws holding everything together. You have to put some grease over the screw holes to stop the diff oil leaking out when you are building it... With the spider it is a little fiddly with 6 gears but with a little time it seemed to go togther ok.

I built the front end last night and it mesh seems a little tight in diff case but hope it will wear in.

I would go with a higher kv than 1700 on the 1512, shoot for 2400kv or so. That way you can gear it lower and spin the motor faster. That will help with the lower torque that the smaller motor will produce. The motor wil still run cool, as the neu motors are fine over 40k rpm, plus the lower gearing will help with amp draw.

Good advice- I'll go for the 1512 2d then, 2550kv, with a 10t pinion or a 2.5d, 2050kv, with a 13t pinion. Which one?
