TRX4M's ESC low voltage cutoff is tuned for a 2S LiPo curve. Run NiMH because it's cheaper and the sag under load is different, so the cutoff trips early or barely trips at all. Match pack chemistry to the ESC profile, not just the plug. #TRX4M #Traxxas

Swapped the TRX4M's stock elastic battery strap for a hook and loop one. Fixes a problem you'd stopped noticing. The stock strap stretches out over a season and lets the pack shift under hard braking. This one clamps the same at day two hundred. #TRX4M #Traxxas

TRX4M's battery tray is cut tight for shorty 2S packs. Packs that drop right into an SCX24 often won't fit the TRX4M tray without trimming foam. Check the pack is labeled for TRX4M specifically before buying a spare. #TRX4M #Traxxas

TRX4M's receiver box has a foam gasket under the lid. Pop it to hit bind, put the screws back, and it's easy to leave the foam sitting proud of its groove. Next damp run, water gets in. Seat it flat. #TRX4M #Traxxas

TRX4M stock tires aren't vented. Trapped air makes them balloon instead of squashing flat on a rock, so you get less contact right when you want more. A pinhole in the inner sidewall fixes it. Free. #TRX4M #Traxxas
