HGLRC 2408 7"?, Motor sizes, wobble issues

Table of Contents:
00:48 - 220X vs 230X flight feel difference
01:18 - The wobble issue...
02:51 - 2210 on 7" wobble
04:00 - HGLRC 2408
05:27 - 2408 on 7" performance
I DON'T KNOW WHY I KEEP SAYING X-ing INSTEAD OF SSING!?

Things I've tried to solve the wobble:
- All sorts of PID, especially messing with I
- all sorts of antigravity settings
- Every frikin ESC setting available in the config including 48k
- inspecting BB for some sort of noise issue
- Talked to maybe 50 people about it which half thought I was nuts
- Finally spoke to a dev that told me it's a known issue.

This is NOT a good 7" motor. good for 6". too small for 7".

Other good 2408 options:
3B 2408: http://bit.ly/2UQsrAL
Hyperlite 2408.5: http://bit.ly/2PDbjO8

My preferred 5" motors:

I actually like 2208 best but cannot tolerate the darn wobbles...

For 7", I've found ~1400kv to be good for 6S and ~1700kv to be good for 5S. The kv can vary quite a bit and you can always use a throttle cut if it's too high for the battery you're using. Keep the throttle cuts reasonable however. You don't want to chop 80% off the top of your power curve because you'll still get super high voltage spikes from the higher kv.

As for motor sizes, I didn't know how good 7" motor performance could get until I tried some larger motors. I now know that 2408 is a good 6" motor size but you'll need more motor for 7" to get excellent performance.

Hold off on 220X motors for now. There is a bug in BLheli/BF that makes them act a little weird unfortunately. :-(

Sub $200 5" build that's still good:
