RE: LST Throttle Return Spring is a Godsend!!!
I took my HPI 1200 MAh 5 cell hump pack outta the Savage and zip tied it to the rear shock tower. It fits perfectly between the two braces and rests on the lower bulkhead, like it was meant to fit there. Put two or three zip-ties across it and it's anchored in there fine until you can find time to grab a flat pack for underneath. No need to take it off for charging either, just plug the terminals into your peak charger and fill it back up. Works great and has lasted me at least 4 tanks of fuel in my LST.
