FLM Emaxx hybrid bulkheads / Ofna hyper 7 diff install problems

[cmac]

I have the HB Lightning diff and pinion and the original pinion had spiral cut gears came with it. I had to buy a bevel straight cut ring and pinion as the spiral version would not fit in the hybrid bulks. I don't know about the Ofna, but I would guess that it would be the same. Hope this helps.

Well I think I figured it out. The diff fits but I didn't realize that the pinion shaft was larger so I'm going to order a set of cvd cups for the front and rear pinion shaft. I had to order the 1/8 scale size and set screw to hold the axle on. I'm curious as to what wouldn't fit on yours ? Was it The diff housing that wouldn't fit in the housing or were the bearings the wrong side ? Post some pics if you have the time please. I had to put larger bearings in the car for the pinion shaft that outputs to the axle shafts that lead to The transmissions.

The FLM hybrid bulks. I did not take pictures during that part of the build, but I thinks it is documented numerous time in other threads. The ring gear in the spiral cut gears are just a little larger( at least with the HB Lightning gears). I needed to buy the straight cut "bevel"gears to complete assembly. I'm not sure if that is true with your Ofna's though.
