Some new parts #'s to update your RB5 to SP specs. :thumbsup:

Mate,

B revisions aren't new part numbers but updated parts, it won't show on an order or on the label.

Proof of that is that I ordered a rear T-plate and got one of those new ones, which I know it is because it had 2 sets of rear hinge pins holders, the original ones and another with the holes moved 2mm outwards overall.

I just saw on the Kyosho Germany Homepage, that UM-505B can be ordered.

They may list them but they shouldn't, as the original isn't produced anymore, it's just a running change on the reference and as soon as stock of the old parts will run out you won't be able to get them anymore. I got one of those and the label doesn't list them as "B" at all.

Still, nice to know what parts have changed!!!

Interesting about the hinge pin holders .....

Yeah I thought you'd be interested. The T-Plate though is the same as has been for a while.

Do we know what's been changed on the hubs ?

:thumbsup: Eh, same difference......you know what I mean..........I just copied and pasted what my team manager sent me from Kyosho America :D
