This is what I have read on the subject. If I'm wrong someone please chim in. I have always run my tapered pistons down to increase the rebound speed. If the information I was given is correct then to me it makes sense because in my opinion you want your tire to spend as much time on the ground as possible so having it rebound faster to me means just that.
If Chicky can chim in here that would be great cause I've noticed he's been running his pistons up according to some of his setups.
The way the taper faces the faster shaft will go that is correct. I have run them both ways, on a super smooth track you can get away with running the pistons with the taper down. On a rough track I could not even make a lap with out wrecking multiple times with taper down. For me the taper up is great on low bite blown out tracks. Other wise I use flat pistons, taper down is not an option for me.

I'm temped to buy the RTR and let my car be for spares. Anyone think thats a dumb idea? The 811 has been out for awhile and I'd hate to have something obsolete or discontinued in months.
Were you using an extra gasket? With the V2 gears you should not have any shims inside the diffs, maybe that was the problem? no shims for v2 gears, one gasket, only fill the diffs with all the gears in it 2mm from the top of the case. If you have the old V1 diffs sometimes the washers can mushroom and cause locking. I'm not exactly sure what your issue is but I'll be glad to help best I can.

The V1 gears have a flange on the spider gears, the V2 do not have a flange on the spider gears.
