Hi all, I'm hoping someone out there can help me. After taking the cars out last night my boys 1/10 scale hsp bug crusher lost its front dogbone as the hub screw found its way loose. I have a spare dogbone though but when I came to check the screw size against the other hub I can't figure out what the screw is. It measure as a standard M3 bolt/screw but the pitch is 0.7 - which is double that of a normal m3 bolt. Am I missing something here or do HSP actually use specialty fixings?? Any help much appreciated!

Thanks for the quick replies! The gearing is 11:1, the motor is nitrotek the HSP branded brushless motor but doesnt appear to have a part or model number. Yeh it does seem like cogging but it seems extreme. I did the throttle setup on the ESC as well as testing in different punch modes but the results are always the same.

Hi to all...i'm new to the RC community and this forum and would like some advice if anyone would be so kind. I recently bought myself and my son 2 rc cars, an ftx brushless carnage - which is awesome, and a HSP bug crusher. I bought the HSP with a brushed motor but after having a blast with my FTX he wasnt so impressed with the HSP...so daddy bought the upgrade motor and esc so he wouldnt want to play on mine all the time! :) After installing the new esc and motor though I ran into a problem. The car is slow from standstill and if parked on an incline won't move anywhere. Once moving everything runs perfect. My initial thougts are maybe the battery isnt powerful enough. The motor specs say a voltage between 7 - 12 is required, I'm running it with 2s 5000mah 45c. But I see nitrotek sell the brushless upgrade kits with an 11.1 volt lipo. The upgrade motor is rated at 3300kv and the esc is model wp 10bl60 rtr. I would have thought the battery would be enough to give a good run off the line in this setup but am I missing something here? Batteries are new so no problems there. Any help would be really appreciated! Thanks
