The fix to the plastic diffs is to use an OFNA LD3 diff case and the steel gearset that comes in that car.
The only issue I might see with the LD3 diffs is that the inner diameter of the drive cups on the LD-3 diffs is smaller than normal. I've tried to use HPI NRS-4 dogbones on this diff and they will not sit far enough into the drive cups to work. You might be able to bore them out, though.
I had a Wolf pack radicals big block conversion on my HPi RS4-2 way back in the day.
does anybody remember this conversion? i think it was being offered exclusively at bruckner hobbies back in the early 2000s
It consisted of custom adjustable motor mounts and a trick little purple anodized flywheel.
I had a big picco omega .21 stuffed in that car. It was stupid fast and stupid uncontrollable.
I remember them...their site is still up but it doesn't look updated at all, after all these years.......not sure they are still in business. I remember Steve Pond used these guys to help build his 100MPH HPI RS4
is done as far as i know . i cant get a hold of them for nothing .
well guys i received my cd3 today so i m going to start hacking on it to fit a big block into it . i really like the cd3 as it has all steel diffs and seems to be really robust so i m going to give it a shot .
a hpi car is going to be my next project if i cant get my hands on a nice 4 tec first (lol)
i will be posting pics of the cd3 progress . i plan on ordering the kawahara wheels tomorrow and start narrowing the rear end this weekend .
