As far as im aware every one has had glitches from walkeras crapy electronics if you are going to stick with this great hobby its worth getting a new Tx , Rx best tobe spcm not fm but you can ask to have i changed by the shop, i have the jrmax66 and donot get even the smallest of glitchs but ive heard that the sprectrum DX6 is outstanding and worth a look, if you like the JR as i do get the 2610 as it has larger screen and 5 points of adjustment for the throttle curve instead of 3 points like my max66 im goin to upgrade to the 2610 id like to get the spectrum but with 2 JR Tx's i can buddy (Trainer mode).
I also have the elf motor and speedy get your self a lipo 2200mah
Yes this sport will flattern your wallet but aint it FUN
