Hi Chris out of curiosity what motors have you got on that quad? It might be that you have a 6s version running on 4s which would make it feel very under powered
I have a 6S Nazgul V2 (1800 KV motors, I think) that I run on 4S, mainly because it was my first venture into 5". I know what you mean about it feeling like a bit of a tank but it should still be able to do all the flippy-floppy stuff.
Once you’ve checked your motors, as Steve has suggested above, you might be able to spice it up by tweaking your rates.
I run my 4S 5 inch on 1450mah batteries, 1800 sounds a lot, and might add a fair bit to the to the weight. Same 2450kv motors, think 2306 (could be 2207). Let me check and weight my battery too
Ohhhh sweet! I felt the throttle was lacking! As the weight with my 4s battery in all is like just shy of 700g! That’s even with my 16g Runcam thumb pro on it Will look at the throttle in a moment
