| Counter rotating axle for scx10 II
I'm wondering if there is an axle for scx10 II which can counter rotate. I mean the ar60 axle of the Wraith can rotate both direction changing the bevel gear side and nothing else. In the Ar44 axle the position of the spur bevel gear is fixed relative to the pinion, so there is no easy way to drive it with a counter rotating shaft. A solution which was adopted with old scx10 axle was to flip it bottom up. Doing the same with an Ar44 axle the upper link mount would go down, so it should be cut and rebuilt some way. Thanks Filippo |

Just a heads up: because of the hypoid design the pinion will end up sitting low if you flip the ring gear. You are right, the whole ring/pinion assembly needs to be flipped. It is not as simple as just flipping the ring gear. The only housing that I know of that looks like it would work is the new Diamond Pro from SSD because it has clearance for the ring gear in left or right position, the third member is a separate piece from everything else, and it looks like it could be mounted upside down with no problems. Diamond Pro Axle Case for SCX10 II There may be others out there as well, but this is the only one that immediately comes to mind. Last edited by RCMFMaxxMan; 11-06-2017 at 01:33 PM. |

Deadloc sells and at least one other company I know of is currently working on a truss that allows you to flip the stock 10 II axle and cut the original upper link mounts off of the axle. | |

I quoted the above posts from another related thread. I thought it was sufficient to put the ring gear on the other side as I can do with Axial Ar60 axles. The only difficulty was to find an axle case where ring gear can be put on both sides and SSD Diamond could be a valid one. Unfortunately it seems that if the hypoid pinion stays up it meshes the ring gear only on one side. So the only possibility to have a counter rotating ar44 axle is to use the Reversed Helical Spiral Gear from extra speed for XS-SCX-2XE #XS-SCX230100, ,(XS-SCX230100) by Xtra Speed #45 Steel Reversed Helical Spiral Gear & Pinion Gear Set 30T / 8T I'm going to search for reviews of this product.

You can also get a lower geared rear axial or higher geared front axle and have overdrive. The toyzuki V2.5 runs 45% overdrive but I would shoot for around 30% myself. The Google sheets in my sig has gear ratios for some common crawler axles.

Why counter rotating axle? People believe it will help to reduce torque twist. Personally I would go for trx-4 axles as their extra gear reduction would cut the torque twist in half on most cars. But to each their own.
