Don't worry, I'm not. Its only been out to the field for testing recently. It hasn't actually flown for more than three weeks now
It sounds like this could be a possible receiver failure.
That's one thing my local hobby shop guy (he's seen the problem on the field) thought since we tried the crystals.
I would look to replace the receiver as an obvious "fix".
If I have to I will replace the Rx, but I really don't want to spend £50 and find that's not the problem, I've already replaced half the 'copter in the last month trying to resolve a wobble. This is why I really have to investigate every possible option before I spend eny more cash.
Have you recently made changes to the radio components (besides the crystal you mentioned); i.e. orientation of the antennae, etc? Was this receiver ever involved in any crash?
No changes to the positions of anything. I did have to put the antenna back in to a new tube because I replaced the landing gear following a crash. I came down heavy after the tail control rod came off while in hover sending the 'copter in to a spin. I really can't believe that crash was enough to damage the Rx though, its wrapped in foam and mounted well. If that's all it takes to damage the Rx, it has no place being in the air in the first place.
What about if the antenna were stressed/bent at some point? If the wire were damaged might this result in glitches like this? I'm wondering if I damaged it feeding it in to the new tube?
