ezrun question

[stuart slmcc]

Hi all got a question regarding an ezrun speedo in my mid mounted losi . Ive borrowed it to give the car a shake down but every time i turn the steering the speedo cuts out . Im running a spektrum sr300 reciver and a ko propo pds2431ics servo. Both worked fine on the novak gtb . Please help :cry:

Could be a broken BEC in the speedo so try using an external bec or an external receiver pack and disconnect the red wire on the throttle receiver connector. You also need to see what happens with a different servo to see what happens.

Tryed an old acoms servo out and that works fine . :confused: just double checked the ko servo works and thats ok on the gtb . Does this now mean a deff bec problem then ? this is going to be a good one to explane to the guy i borrowed it off .

not neccessarily duff bec in speedo its possible that the BEC is working ok its just not "meaty" enough for the ko servo but the old acoms doesnt draw enough current to trip it out . I had similiar experience years ago when digi servos were first launched :confused: took me ages to work out what was going on . Newer top end speedos seem to have his issue sorted
