Infraction arrma infraction 8s speed run fail.

[Colinwarburton]

love running this beast on 8s!
all goes well at first, but then my esc cuts out, after the run i noticed my tire was dislocated from the ball joint, and the pinion gear shifted separted from the spur gear on the motor
i did a speed run because i wanted to see what my gps would record, i recorded 60 peak speed, its going quicker than 60 BUT Thats because i prob let off throttle at the beginning, need to figure out why.

looks like i need to change some parts or attempt again
your thoughts?
8S is wicked fast

specs
blx 2050 kv
max6 esc hobbywing
2x4 lipo batteries 50C 14.2 volts 5000mah 7.4kwh
24 pinion 50 spur

You should hitting 100 mph with that gearing on 8S.

It's fast for sure. If you let off at 60 mph then got back into the throttle and went faster, the GPS should have picked that up and recored a faster speed.

You should consider the Limitless spool too. ??

I have that. I haven't used it yet. My hobby guys tell me ill lose acceleration, but gain top end. And that the tires will all spin at the same time, also that with the limitless spool, i wont be able to drift because of the differential sending power to all 4 tires at once.
I figured out why it cut out, it was my antenna iost signal

Yeah if you’re drifting, stick to the diff. If you’re going speed running, use the spool.

That actually looks like 60mph to me. 90+ is going to shock you
We have seen quite few of these threads lately. The hobbywing ESCs are not good for speedruns, they cut out from amperage limits. I have yet to see one on this forum break 100mph, but creeping into the 90's is possible.

Your current gearing "could" peak around 75mph. If you want to play with speed more I recommend going with the Limitless spool.
Watch motor temps closely after each pass. You are running much more voltage through that motor than the "norm"

I heard that castle is releasing a new esc soon

Oh boy

Yup sure are and getting ready to start running full production again. Can't wait.

 

[LibertyMKiii]

Not holding my breath, but it would be great to have a new option. That market has been unchanged for years...

Right on. I think the x esc series is almost 5 years old now...

Been watching this for a couple weeks now... its getting close.
