RE: Glitching = crash, any reccomendations?
My two cents tells me that the cause of the twitch might be the chicken pot pie in the microwave. If you are still on FM you are at the mercy of so many things like microwaves, anything electrical. I used to have an axe cpv3 than when in the house or in my neighborhood would just twitch like it was having a seizure, took it out to the park or out in the open and solid as a rock. You don't have to get Spektrum or Futaba or anything highend just any radio that is 2.4 ghz will do the trick. Do I suggest you get a good radio... yes! They aren't that expensive. I bought my spektrum dx6i of ebay for $108 and love it. You might have other issues going on that is causing the fits of excitment in your bird, but I would bet it stops if you take it out to the field.
Also check all your connections see if they are loose. Good luck!!
