HairyGranola Posted January 1, 2013 Share Posted January 1, 2013 Hi guys, I bought a second hand hyper 7 a few weeks ago and finally out with it. Anyway it starts up fine and idles ok, just needs some idle tuning. However whenever i rev it it goes crazy and shoots off. Had to chase the damn thing a minute ago. It has the .21 and a jp-3 pipe if that helps. The tuning looks out on both needles, not sure if that could be a problem or not z Thanks Quote Link to comment Share on other sites More sharing options...
m0th Posted January 1, 2013 Share Posted January 1, 2013 try setting it back to stock settings and make sure the carb is closing all the way. i use an elastic band round the carb on my hypers just to give the carb a little extra closing power.

JFS666 Posted January 1, 2013 Share Posted January 1, 2013 if your unable to stop the hyper it sounds like a servo problem! does your throttle servo engage the breaks ? try it without the engine running ! Quote Link to comment Share on other sites More sharing options...
HairyGranola Posted January 1, 2013 Author Share Posted January 1, 2013 That sounds about right, it came with a spare savox, it engages the breaks but the servo twitches loads. It only high revs when the servo is in use. Quote Link to comment Share on other sites More sharing options...
mugen mark Posted January 1, 2013 Share Posted January 1, 2013 (edited) you useing aa batterys in your recvier?,the shooting off problemis not tuning ,it radio/receiver cutting out,good batterys in both rx/tx? for the rx a 6v hump pack better and gives longer run time,also check how to set your failsafe if it 2.4ghz and make sure it set to neutral,that should stop it if it out of range, or out of power,or the throttle servo on it way out Edited January 1, 2013 by mugen mark Quote Link to comment Share on other sites More sharing options...
HairyGranola Posted January 1, 2013 Author Share Posted January 1, 2013 Using a stick Pack for reciever. Im gonna switch throttle servo when i get home. Hopefully that should do the trick, and ill reset all linkages aswell Quote Link to comment Share on other sites More sharing options...
HairyGranola Posted January 1, 2013 Author Share Posted January 1, 2013 I fear it could be an air leak, new servo in, carb gap is 1mm, brakes engage fine, carb opens fully and closes back to 1mm. Still high revs Bummer. Quote Link to comment Share on other sites More sharing options...
big turbo Posted January 1, 2013 Share Posted January 1, 2013 (edited) I fear it could be an air leak, new servo in, carb gap is 1mm, brakes engage fine, carb opens fully and closes back to 1mm. Still high revs Bummer. It's not a air leak or anything to do with the tune as its not a mechanical problem. It must be electrical are your sure your tx pack has a good charge in it? I would check the voltage in it. Does it do it when its not running ie servo messing about? Most built in fail safe's do not have low voltage detection Edited January 1, 2013 by big turbo Quote Link to comment Share on other sites More sharing options...

HairyGranola Posted January 1, 2013 Author Share Posted January 1, 2013 Cheers for the help guys. Charged up the rx pack even though it was pretty full . Took the engine out, checked for leaks, just for reassurance really. Reset all needles and it seems to have sorted it. Thanks 1 Quote Link to comment Share on other sites More sharing options...
