Help!
Why does my blade mqx fly like s@#t?!

After several crashes and dorks, my blade mqx flies horribly! At hover or slow forward flight its fine. How ever,, at high throttle it wigs out, starts tik tocking, goes into a wicked cycle of over correction and then crashes.

Reason I am concerned is it takes high throttle to flip or roll the little bugger,, and as of now, al I got is about up to 2/3 throttle before it starts freaking out.

Check your motors all spin freely with the same lack of resistance. Make sure all of your blades are tracking nicely, bend them if not. Check the gears. Try a fresh battery.

After a few crashes, your motors and your props are not as evenly matched as they were when new. As a result, the mini-computer-brain on board the mQx has a much rougher time getting power levels correct at full throttle. When you go full throttle, let's say that one motor is giving the highest level of the four. The other three are close but not spot-on. That means the "high" motor is going to start to cause a flip. The gyro circuit on the mQx is going to try to compensate, but it over-corrects and you get what you've experienced. The above description is for one motor, but if you've got two that provide full power and two that don't, you can really have a handful.

After losing one somewhere in the neighborhood trees, my replacement was very nearly perfectly balanced. It still had some, as you put it, tick-tocking when I went full throttle. My lesson after another out-of-control flight termination from such behavior is no full throttle.

Mine flies just fine only time i ever get what your talking about is at full throttle the fact is its not brush-less thus not as precise...

however check for twisting of the arms I once split mine down the side and it would twist and cause it to go one direction or the other but not as bad as you described They will twist a bit but should not be very easy to do so more then 1/8 turn if you can get more twist and its easy to do so then you prob should replace you arm. its easy and parts are cheap all over ebay

Alright,, so i replaced all 4 props and its flying much better. I think 1 or 2 of the arms are cracked though. CA did not fix them, and they do twist just a bit more than the other 2 arms.

I just want to know what you did to get it to tick-tock. That would be awesome!!

It was like a reverse tick tock as if the fulcrum were above and the arcing path of the heli was below. It would swing side to swaying and rocking. All I had to do was give full throttle and it would do it. Now with all 4 new props its much better. But the aftermarket body its got has thrown off the balance.

If you don't crash once in a while, you're not flying hard enough
