rag6, Reading your post gave me the moment of clarity I was looking for. I had an understanding that a diff locker added a bit more stress to the shafts, simply because the wheel with grip would still get full power to it, but I had no clue just how much extra force it actually put on the shafts. The education is always appreciated! I also hadn't thought about this added stress since I had started using the diff locker (about a year ago) and completely overlooked It when I was snapping sl4sh shafts like crazy recently. Even when I ordered the new lockers the other day, It didn't dawn on me that this is likely the reason why (besides the massive power plant) I was snapping the shafts so easily. Thanks for bringing this to light, cuz even though I have found the shafts that will take the torque from this brushless system, I am the kind of guy that likes to know exactly what' it is that I just fixed. Lol.
As for the weight differences of the shafts, geez man! You coulda asked me this BEFORE I put them on the truck! Haha. No worries, I took one off the truck and weighed it up for ya, as this is likely a detail that others are wondering about as well. I also took the weights of the other shafts I have as well for a comparison. All weights are measured in grams, Here ya go:
Stampede vxl 2wd stock shaft:
Slash 4x4 stock rear shaft:
Hpi savage xl shaft *modified*:
Shiny hardened steel "integyish" cvd:
Junfac hardened steel cvd:
Mip x-duty cvd:
Now that I have run about 20 packs through the HR P2de with the mips installed, I really don't see any reason why I need to destroy the shiny steel shafts by pitting them against the et-2400. They do look like they are built fairly solid, but not 2400kv on 3s solid, if ya know what I mean. ;-)
I will however, be installing the shiny cvds on the Po-Po-Pede Hummer which is powered by the vxl motor and the castle/dtx esc on 3s lipo, and I will post a review after I've run them for a bit. Same goes for the rcdamper cvds that still haven't arrived yet, cuz I have my doubts that they will even hold up to the vxl on 3s because of the weak looking u joint system they employ.
I have quite a few more things in the works for the HR p2de yet. So stay tuned! :-P
