Ofna Spider diffs. How are they? What do they fit?

[transtalon]

I have one in my muggy chassis Lst2 1.5" extended. I'm running the 80 mm
2000kv Medusa with a 6S 8k 25C Maxamps and they work good. they are
very strong but it's made up of aluminum housing and a steel gear so it's on the heavy side. It has six side gears for a total of 8 unlike the traditional 6 gear setup. It fits just like any other center diffs, they have the length like the Hyper 7 and OCM Kaos.
