Back from the dead with the big block revo that cannot be killed!
Shelved it again for a while due to the ongoing 'exploding slipper gear' issue & the 'busted rear diff' issue, bought a mini erevo brushless to take out with the kids.
A neighbour asked me what happened to that noisy wheelstanding RC thing I had a few months ago commenting that it was cool as poop.
So I dragged it back out, cleaned the crap off & got it up & running again - & solved both the slipper & diff problems!!!!
Slipper turned out to be a dead easy fix, I just slapped a stock TRX 38t plastic slipper gear on it & loosened off the hot racing slipper - gah! the amount of $ I've wasted on fancy steel gear setups brings a tear to the eye. The steel gears don't like shock loading, they shatter or loose teeth, when the chassis flexes on a landing or crash it belts the clutch bell gear into the slipper gear & hurts it. The plasic gear just flexes a bit & is unharmed.
Another upside is I haven't sheared a single pin in the trans since I started using the plastic gears.
Constantly exploding rear diff was fixed when I realised that the integy alloy carrier was a bee's nasty too wide between the pinion bearings, putting them under tension & chopping them out real quick resulting in metal all through everything & a very limited diff lifespan.
Fixed with a dremel.
Hasn't broken a slipper gear or diff since & it's been beat on hard.
The old solidier Losi 454 got a RAG rebuild a short while back as well, I picked the biggest of 3 pistons & the smallest of 3 sleeves & the best of the bearings & slapped it together, good compression, idles nice, holds a tune & makes plenty of grunt - go figure.
Just gave it a clean up after a couple of hours at a BMX track on the weekend, it came home still driving.
I guess it may be finished now, just maintenance from here on I suspect.
