I have added Blue Tac in my Hyper 10 rear diff, opened it up and did notice that the blue tac after 2 meetings at local hobbie track it did soften up! However it worked great, got much better power out of the rear wheels on my Nitro RC!!!

I have repacked the diff again with new Blue Tac, and cleaned all the grease i had in it before, ill see how i go next round and shall post some pics to see how its done....! I guess its a cheap way out of it - note no damage was found YET


cheers
