Blown both Diffs in brushless lst?
Took my lst out for its maiden brushless run,
I'm impressed with the handling and glad I fitted the losi wheelie bar,
There started a loud crackling noise at the rear, which got worse until rear drive was lost just 10mins into the run,
Then the crackling noise switched to the front, until all drive was lost,
I'm running a 4074 2364kv motor on 4s 5200 with a 25t savage flux pinion,
With a 63t spurgear,
I had the Diffs meshed perfectly and was surprised the lst Diffs didn't last a full lipo charge
Are there any upgrade Diffs that fit the lst trucks?

The ring and pinion gears are destroyed, the diff cup is perfect still

Found the problem,
the plastic holder that the diff and pinion gears sit into have 5 or 6 fractures each this allowed the gears to mesh loosely under load and stripped the gears,
I'm going to look for complete lst2 or xxl Diffs with the alloy cases.
Know anyone who sells complete lst2 or xxl Diffs with outer cases?

RE: Blown both Diffs in brushless lst?
sparky, I am in a process of upgradring my lst to brushless, about the battery, would you recommend the 4s or 6s? this will run on mamba 2200kv, I heard 6s is too brutal to run but just not too sure before I place an order w/hobbyking...thanks.

I run my savage flux with mamba 2200kv on 4s,
Trust me its bags of power,
I'm running a 2364kv motor in my brushless lst and with 4s it would be undrivable without the wheelie bar,
The only thing you really should buy is metal diff holders as the stock lst plastic that the Diffs sit into will fracture first time out,
I had mine shimmed perfectly and got just a couple passes before I could hear the Diffs crackling,
The best batteries for the money are turnigy hardcase 30c 2s 5200 batteries,
I also have zippy hardcase 30-40c 2s 5200 batteries, but the turnigy definitely have more punch to them,

Hello,
My Muggy came with plastic diff case and the LST2 XXL diffs comes with the 8T heavy duty diff cups. My LST and my aftershock also had metal diff case.
