Thanks!
By the look of the video (cool drifting going on ) very light rain the car shouldn't malfunction like your experiencing. Not sure how long you have owned the car but if your under 12 months from time of purchase (if purchased new) I would contact Hpi customer support and explain the issue if you haven't already did so. Having the serial number of the car and proof of purchase receipt will insure you getting warranty replacement parts backed by Hpi. Hope this helps so you can get back on the road.

I forgot to check back in here. I ended up ordering a new receiver and servo and that did the trick. Thanks for the help!

Steering Problem is back. . .?
Back in November I ran my last Fastest-Lap Challenge for the year. My son ran a bit off the track and ran over a large bottle cap. After the run-over; we heard grinding and then checked the chassis. I found a broken camber-link ball-cup and the suspension-arm was carved-up from the swing-shaft.
I installed a new camber-link ball-cup (I also installed a new ESC and motor).
Now the chassis pulls to the left.
-Can a rough run-over cause a steering problem?
(I have an old - but works-fine Futaba 9451 Servo in the chassis. I'm go'n to try the stock servo and see if it gives the same problem.)
Thank You

Yeah, this problem is almost certainly the result of a steering adjustment error. However, you should also remove the wheels, disconnect the axles, and spin the wheel bearings to make sure none of them are binding. If they are, you may need to insert shims between the inner and outer wheel bearings to keep the bearings from being pinched when the wheel hex is installed and tightened into place.

You'll have to wait a few.
A few hobby shops have the part. . .Active Powersports has it...?

Thanks for the info grabbem88 and fyrstormer.
I've said this before: There's a lot of play in the Steering (from the Bell-Cranks). I have a HPI Pro 4, Tamiya TT-01, Tamiya M-06 and Tamiya TB Evolution 5. They don't have as much play in the steering as this Chassis.
(I've installed the Spool in the front. It shouldn't cause any left or right pull'n problems.......?)

How’s the spool? I thought about going ball diff front and rear on my sprint 2
I know this is the sport 3 but as most experienced with the 2 it had slop everywhere
I did rpm ball cups yeah racing bellcrank and hub carriers did the mod on the left side where take the two nuts bearings and a bolt
There is zero slop handles better than my tc4’s and Can hold a line

I just received my upgraded Savox servo. Installed it and I'm not getting any power to it. I unplugged it and plugged in the stock servo. Now that one only adjusts to center but doesn't work either. Did I make some kind of error? Being a newb I assumed it was plug n play.
#1018
It is, as you qualify yourself as a newb, I'm gonna try to be precise...
The servo is powered by the receiver (RX) via the BEC provided by the ESC. So if your servo won't move, there are some possibilities:
- The car is off lol
- The servo is not connected properly to the RX
- The ESC is not connected properly to the RX (so no power in the RX)
- The RX is using a mode not supported by the servo (SSR or SHR), only on Sanwa
- The servo is fried
- The RX is fried
- The ESC is fried

The Spool works well. No loose play parts on it.
I held and ran a Sprint 2 (my wife's nephew's chassis). I agree. It does have a lot of play on some parts.
I understand what you mean with the Aftermarket Parts. I just don't install them on any of my chassis (any major parts).
