15 flights now ,, awsome but the good news,, got 2(so far hrb 6000 4s ) 8s woohoo.. take out the 6s put in the 8.... just early backyard testing,, so far very surprised,, by calculation the 6 s 1835 kv spins faster than 1350 8s,, by 1000 odd rpm,,,, but the low torque. Like a big block chevy.. compared to small block... 4 and a half minuts and 378 per cell woohoo.. just gota work out cg and find that 8s battery strap.. im excited all over again

8s done and dusted,,, wow like a new plane,, think the xtra 300 grams makes it more locked in.. take off speed reached way quicker,, flys well at 50 or 60 percent throttle,,, awsome value up grade,, i think its an 8s plane..... for sure. Flap mix is out now so cg must b a bit different,, 4.5 minuts mixed at 3.75 per cell did glue in little foam blocks to stop battery wobbly wobbly with 1 strap

Excellent News, f4u aussie!! Looks like you have a great combo there using 8S. I think if I buy another F4 someday, I'd start it out at 8S power. Mine does ok right now, got lots of flights on it with 6S, but I'm intrigued to see what it could do with 8S power, especially up here at 5000' MSL!

Good job!

Welcome to the 8S club!!!🤙 Told you you'd love it. I believe this model is made for 8S. Even more stable when it's a bit heavier, also found it flies/lands better balanced a bit further back at 200mm where I believe my 6S was better at 194mm. Couldn't believe how much better it is on 8S. Changed my FW 90mm F16 to 8S also, a sizable enhancement all around, but the F4 showed the biggest improvement.
