Mountain cruiser, gonna hit some mountains in Snowbird, Utah (with permission from the resort). This build is my first foray into butterflight. It's got a Helio FC in there but everything else is my usual build, HW 4:1 ESC, F80 2200kv, 6" gatebreaker s and my favorite battery for mountain flying, the 2200mah 5s. Got some great morning mountain dives on a fully stock tune, only think I changed was my rates. I think with a bit of tuning butterflight and the helio might be my new go-to.
