Alright a bit of an update. The Basher 6Kg servo died after about 3 minutes of bench testing. Good news though. A quick video of the dead servo and a few minutes of chatting with the staff at HK on the live chat link I was credited for the servo without having to send the dead servo back to HK. Waiting for a stronger faster digital servo from HK.(Looks good and gets good reviews.)

BTW more good news regarding the front CVD's. The pair I bought work fine in the rear. Now I have CVDs all around. Other sites are charging 4x HK's $12.99 for the 1.5mm shorter ones from Team C.
One thing I have noticed is that the shocks are fairly stiff and the springs are too short to allow much of any down travel. I have found that HPI makes several springs for their big bore shocks that have an internal diameter of 20mm. They offer several lengths and spring rates. I am hoping this will inexpensively create a better off road suspension for the rally.
You do need to add thread lock to all of the metal on metal screw points on the chassis. The only thread lock I found was on the grub screw holding he 17mm hexes on. None on the motor mount to the chassis or on the motor mount screws or the pinion grub screw. The grub screws on the front and rear drive train also did not have any thread lock.
Check the gear mesh on the pinion and spur gear. Mine was way too tight and screamed when running. Once it was adjusted it was much quieter.
Lastly, to calibrate the ESC follow these instructions as there is none from HK yet. This is copied from the US West warehouse discussion board about the Rally.
"ust calibrated my Futaba. 1) Turn radio on, 0 EPA, ABS off, Rev Throttle, 0 EXP 2) Hold down button next to on/off switch and turn on while holding, keep holding until green light comes on, then let go, pull full throttle (red light goes on), push full brake (green light goes on), release throttle back to neutral position and wait for green and red lights to flash together. When that stops you should be ready to go. Don't know about programming card, still trying to work out who made the esc."
I will update when I learn more. Cheers.
