Thank you sir!
Upon some thought, I think I'll prefer Velcro straps. Getting the cap screws in and out is a pain, so I think Velcro is the way to go for me.
Maybe I'll flip those headers while I'm at it 😁😁
EDIT: Not flipping the headers. I googled pics of actual monster trucks and all of them had the headers faced the way Losi has them.
Also, Horizon is sending me a full batt tray set tomorrow free of charge. Excellent customer service. 👍🤘
