i have a 4pks and when esc is off and 4pks is on if i shake the remote it beeps. every time without fail if i wiggle it left or right it beeps....

defective switch, contact Futaba. Try to be a little more articulate when describing the problem to them.

i got the same problem..and my receiver were damaged because of it..it happened last week

I Contacted support at Futaba. the guy said its the first he's ever heard of the problem and that i'd have to send it in.

Zig- are you speaking with experience?

chico- did you have the problem fixed?

I'm going to tear mine apart and look for loose wires before i ship it off and waste all that time. as it seems it just recently occurred. even tho its never been dropped and always stored in futaba case.

dont take it apart your not the only one that this had happen to it has to be sent back in to be reflashed this happen to me friends and futaba had to reflash it to fix it
