When I flew the Blade stock with the supplied Tx and 4&1 the glitches were common, but when you get the hopping or slamming down there's a few typical failures to look for:

1. Unplug the motor, and links from the swah and make sure the servos are all working properly. Move the collective and cyclic slowly and make sure they don't jitter, these servos die pretty easy, if you have one weak one it'll cause this.

2. Make sure your main motor isn't toast, sparks from the brushes will cause interuptions, and eventually cook the 4&1 if you don't replace it.


The Blade is a good little flyer, I have my own tx and a HH gyro, but still use stock motors. You'll be surprised how much more stable and smoothe it is if you tweak it with a good Tx.
