Jamie, I reached out to Andrew to find out what he was finally geared at, when I find out I will post it.

question for you guys I have viper 17.5 in my sons rb5 buggy. where should I start gearing at for him right now its at 72/30 which I think is to low. Looking to get the most out of this motor with out boost. he has only been racing for about a month

I had my buggy geared at 21/78 and i was talking to one of the local fast 2wd guys today ( he drives an RB5 with a 13.5 too ) before the quals started and he said i was under geared. He recommended going up a few teeth on the pinion. I did and up to 25/78 and it seemed fine, but lacked bottom end grunt. On the straight about 1/4 of the way down it really started to fly. Would dropping down to the 22 / 23 T pinion really have made that much of a difference? It was working ok, and I was having a real hard time with my new 4wd so i left it

Speaking of my 4wd. I was running a 13.5 in that too and it felt REAL slow compared to my 2wd. Hardly any bottom end and real slow down the straight...seemed to top out. I had it geared at 25/80 then went to 28/80. That seemed to help but, was not a whole lot better. I used to run a 10.5 in my B44 and it flew. I now have a different 4wd. Going from a 10.5 to a 13.5 should not have felt THAT much different should it?? I was not running a Viper ESC in my 4wd, it didn't get here in time. I was running an Orion Vortex Race Spec ESC.

hey guys. i just had a question regarding the motor timing on the vst motors? what is considered 0* of timing? is it when the arrows are pointing at both 30 marks on the outside of the can? and which way would i turn it to increase timing on the motor?

I ran a 72/29 on my B4.1 with this, average size indoor track. And yes 2-3t will likely make a huge difference, especially with 48p.
A 13.5 is definitely slower than a 10.5, especially depending on your level of boost, but since you had the Orion esc in there I can't comment on that very well. Were you running any boost with the Orion esc?

Comparing our gearing for our 2wd, it seems like I was under geared. I was concentrating more on the problems with my 4wd.

I bought the Orion second had a few years ago. It worked great with the Orion 10.5 I had it paired with. Finding any info or specs on the esc is next to impossible. All i could find was that the drive frequency has a linear decrease from 12.146kHz to 2.04kHz.

I tried everything from a 21 - 28T pinion with my 80T spur, it felt like it might have been a little better with the 28T. The gear ratio in my 4wd is 2.437

Are any of the sponsored drivers with a VTX10 ESC running a Savox Servo? I was wondering if there have been any brown-out problems like others have experienced with other ESC's and these servos. I'm not totally convinced its a BEC issue because my LRP ESC has only 5.5v/3A BEC and works fine with savox servos. Seems to be limited to Spektrum receivers. Any input? Curious because I plan on buying one of these units upon release.

I believe that the orion ESC is really just a rebranded KO BMC. check the KO website.

Not having a SINGLE issue. I have run the caps on them and without, and never had a problem. I run KO and Futaba RX's.
