RE: I dont get it ....!!!!!!
I just answered another HITEC glitcher on the post above you. read his problem.
Did your 2 sets work OK for a long time & now both develope these range / glitch problems ?
If both were OK. I go for Jamming by a person or a microwave tower " splattering your field with glitching.
Take your wings off and test them at a DIFFERENT site. FAAARR away. Goverments & armed forces test jammers all the time.
......EDIT....... CAREFULLY with a magnifying glass if necessary. Check the WRITTEN frequency of all crystals. I misread ch 18 as ch 16. MAKE SURE the TRX crystals are in the trans. Call or EMAIL ....HITEC. They may have your problem already.
Please post back for others
DO NOT TRY TO FLY UNTILL you gear works on the ground or a table with a rope holding the plane in place
I am assuming your batteries & charger are fine.
I forgot. Both new. Send them bak NOW. You will only damage servos gear teeth if they chatter a lot . Rapid yanking the gears at maximum ruins them. Send everything back.
