Pitch kicks in suddenly while throttling up?
By JD and Atzanik:
If pitch comes in suddenly:
Checklist:
Also if you hold it in your hand over your head and you slide the throttle up and down do you see all three servos moving up and down? One of your servos may be dead or dying.
Are your blades Tracked?
Do you have both silver pins in your Aluminum T block?
Is the set screw on the Tblock in the flat spot on the main shaft and is it at the top of the flat spot?
Is the brass retainer on the Tblock all the way tight?
When you grap the blade holders like a cork screw handle and pull up and down on the head, is there movement, does it slide up and down? There should be no movement. The main gear should not move up and down.

Other than what JD already mentioned, check your blade pitch. If everything that JD mentioned checks okay, it's either your pitch or head speed (due to either motor or battery power), or a combination of both.

Then, JD added:
All I can think of if what you say is true, that your TX/RX are giving the wrong commands , is to check that all the dip switches are in the original positions and then and if they were then open the radio up and make sure all the connctions are soldered on good. when pulling back on the stick of course the two rear servos move down and the front one should move up twice the amount of the rear ones so you maintain the same pitch. I guess in both scenarios - full forward and full backward. You level the fly bar and measure or look at the pitch and that is how you know it is changeing.

Brushless Main motor upgrade
I have the walkera brushless upgrade kit (motor and esc) and stock tail motor, with 1250mah 10C battery. It works fine! Just one burnt motor after 7 months of flying (with breaks. Sorry I can't provide flight number.). Please note I usually let the motors rest every 4-6 minutes. Dual heatsinks and thermal paste used on tail motor.

Walkera 22e Basics
After reading and posting in the thread named "RE: Walkera 22E Lets Talk", in rcuniverse.com, I decided all the important info should be gathered and separated from the chat we were doing.
So this blog is an effort to concentrate the most important posts from that thread.
Any expression like "the forum" in this blog refers to that thread.
