Honeybadger Posted April 18, 2014 Share Posted April 18, 2014 As its so new your best thing to do would be to contact Modelsport and see what they say. Quote Link to comment Share on other sites More sharing options...
Shudson Posted April 18, 2014 Share Posted April 18, 2014 Silly question, but you have charged the receiver pack? Quote Link to comment Share on other sites More sharing options...
JamesBryan Posted April 18, 2014 Author Share Posted April 18, 2014 (edited) Tried Modelsport but they dont seem to want anything to do with it. Receiver pack was brand new a few days ago and charged for 16 hours. Edited April 18, 2014 by JamesBryan Quote Link to comment Share on other sites More sharing options...
Honeybadger Posted April 18, 2014 Share Posted April 18, 2014 I'm surprised by that, Modelsport customer service is normally very good. Quote Link to comment Share on other sites More sharing options...
BigJayB Posted April 18, 2014 Share Posted April 18, 2014 my bullet always did this when using normal AA batts in the car lucky enough it never crashed but i remember once it running off stopping when i got near it pissing off again changed to a hump pack and never had the problem again Quote Link to comment Share on other sites More sharing options...
JamesBryan Posted April 19, 2014 Author Share Posted April 19, 2014 I'll stick the hump pack on charge for a bit longer and see if that sorts it Quote Link to comment Share on other sites More sharing options...
Carlito13 Posted April 22, 2014 Share Posted April 22, 2014 It could be ur servo the stock ones are no good I killed both stock servo's within half ahour after useing a hump pack, I would get high torque servo as the stock ones are no good and not powerful anuff especially for the steering Quote Link to comment Share on other sites More sharing options...

I've tested it again with new AA's in the battery holder and it runs fine. Had a volt meter on the new hump pack after 24 hours of charging and it reads 4.5v and the charger light doesn't light up any more, so i think it's faulty. Got a replacement on the way.

Morpet Posted April 24, 2014 Share Posted April 24, 2014 (edited) Bought a HPI Bullet ST 3.0 last weekend from Modelsport. Been running it in the past few days. Took it to a big unused car park today and something weird has happened... It took off full throttle into a kerb and smashed the front up. It did this all on it's own with absolutely zero input from me. I applied the brake and it did nothing, i then switched the radio off thinking the fail safe would kill the throttle and that didn't do anything either. What has happened?? I had the same problem with mine mate I called hpi spoke to mic he sent me a new servo never had a problem since. I always deal direct with hpi now mics a great guy. I've had a set of new dog bones and wheels from him as well all free of charge all he wanted was a few pics. Excellent service Edited April 24, 2014 by Morpet Quote Link to comment Share on other sites More sharing options...
Morpet Posted April 24, 2014 Share Posted April 24, 2014 I've got a hump pack fitted as well now makes a world of difference when turning at speed. More power to the servos Quote Link to comment Share on other sites More sharing options...

andy1677 Posted April 26, 2014 Share Posted April 26, 2014 hi this happened to my hyper 7, was working ok with the throttle and brake, took it out onto the field and next minute full throttle with no input from me, still had steering but no throttle or brake, failsafe would not kick in. it ened up to be a break in the servo wire from the throttle servo to the receiver,new servo and it works like a charm. on mine it looked as though a screw had one of the wire and it had exposed the core... would recomend double checking this, uprated servo is about Quote Link to comment Share on other sites More sharing options...

JamesBryan Posted April 26, 2014 Author Share Posted April 26, 2014 Hump pack charger was faulty, so it wasn't fully charging the battery. Replaced for free. Quote Link to comment Share on other sites More sharing options...
