Hello FoamO
I am using a 6s and a 2s, same brand and milliamp. I like this combination because it still allows me to use my 6s packs in most of my other EDF’s. I have had any issues.

I am not using 4+4 nor roaring top… 6+2 and I have a few different sizes and brands from 5200 to 6200.

Are people mainly using 2 Roaring Top 4s batteries? And if so, are they using the (4s) 70c @ 5000mah or is the (4s) 80c at 5100mah better? Thanks. I’ve dug through pages in this forum and found tons of good advice (changed my elevator servo to the Hitec) but can’t find definitive answers on the battery

" but at +$200 for a piece weighing 25% less, it better be hand massaged Kobe beef! "

Just back from a good flight with the beast .......full arsenal aboard..went great till wind got up just on start of approach when the wings started to rock a bit ! Got down OK and but didn't half wake me up!!
Went back again after dinner to a beautiful calm evening with not a soul in the park. Stuck in the HRB 6000 and had the best flight ever. Gave it the full 4 minutes and came in with cells down at 3.75 -3.70. Battery was warm but not hot. LUVIN IT !!Last edited by locharrow; May 22, 2021, 02:52 PM.

Does anyone here know if the ESC timing on the stock 150a ESC included with the 8s Phantom can be changed to 5-6 degrees? Or what it’s factory settings are?
Thanks

EA-6B Geek here's a quick video of one of my F-4's on that WPU ("Wiedman Power Upgrade" ), do it, you won't be disappointed (unless you want to go 8S, which would be even better, but more money and maybe new batteries to work with-I have mostly 6S, so not a great option). I've posted this before, but who's counting. You can skip to the end to see my "low approach & evade the radar" (especially the FAA) landing sequence. Much easier to sneak up on the ground based bad guys and any SAM sites. In and out before they know what hit them!

"If it were my landing I'd hang my flight jacket and retire, no improving on that ... 😎" Quote of the month smithy .......wish I had done that to avoid the embarrassing misses that followed a great opening shot at a pheasant shoot once, heaven to hell in one day!!
