signal response

[markymark6183]

hi guys
right i got a problem after about 5 mins of running time and about 15ft away my madrat has a signal delay of about 2 seconds i.e when i steer right nothing happens for roughly 2 seconds the areial is srewed in tight and the areial from the rx is in its normal place, the battery only has 5 mins use. when the rat comes back to me the response time is back to normal. am i missing a trick somewhere along the line

cheers in advance
