I see this issue posted on a lot of forums, and I discovered that it usually means a servo with a broken gear tooth.
If your Blade jumps up and down in a hover, one of the servos has a stripped gear or broken tooth.
When the Blade jumps up and down, it's right on the area of the gear with the missing tooth.
The first servo that failed began to twitch when I first powered up the 4-in-1.
I thought it was a glitch.
As it got progressively worse, so did the glitchiness of the servo.
After I discovered a broken gear tooth, and replaced the servo, no more glitches.
The servo was never actually glitching, but trying to center on the missing tooth, giving the false impression of glitching.
The tooth will crack first, and then finally break off, magnifying the problem severely.
It really played havoc in a hover, too. The Blade would nervously jump up and down erratically.
It also lost lift, as two servos were trying to do the work of three when changing the pitch angle.
The E-Flite/E-Sky servos always break the same gear tooth.
Here's the guilty party:

I've had two servos break teeth on the identical gear.
The gear that meshes with the servo horn gear is always the one that breaks.
Here it is, innocently sitting there:

You need to remove this gear and inspect it. If it's meshing on the broken tooth, these gears are so tiny, you won't see it.
I'm assuming it's the gear that takes most of the load and impact in a crash.
If your Blade was flying fine, and after a crash, or over a long period of time, it suddenly jumps up and down in a hover, is impossible to control, has lost lift, and appears to have developed a glitching servo, check for that missing tooth.
I'm discovering that most of the problems on the Blade/Honeybee are mechanical, and the poor 4-in-1 is always the one accused of being guilty first.
So, before tearing your 4-in-1 apart, check those servos! :lol:
