Default Novak Havok 2S EXTREME STUTTERING

Hey guys! I have a Losi Desert Truck 1/10 with a Havok 2S system that used to run perfectly. Yesterday, it ran fine, it could even hlod a wheelie from a stop. Now today, under the same conditions, when i full throttle, it stutters like some kind of traction control is kicking in. After a couple seconds once it starts moving it runs fine. The problem only occurs from full throttle, even from a pushed start. Help me out please!

What battery you running? Do you have the lipo cutoff on?

Could be a battery issue or gearing issue...

As i said, same conditions. Same 2S lipo with same gearing. Everything fits correctly, mesh is set right. Yes lipo cut-off is on but i fully charged the battery when i tested today. Also, full throttle reverse works perfectly.

Maybe set the esc back to defaults and give it a try.

The thing is that the esc is already at defaults.

Try a lower tooth pinion gear.

Ok, I know your smart enough to look at the sensor wire for breaks etc. Look for a member called "NovakTwo" he works for novak and will take your info and let you know if they can fix it. May just need to be flash programed again.

You sure its not the tranny? really sounds like the gears slipping in the video. but trouble shooting over the net is hard. Hope you figure it out.

My Havoc 3S stuttered like that right before it went up in smoke. It was only about 2-3 packs run through it at the time. I sent it in and got a new one back, the cause they said was multiple mosfet failure. Not saying that's what wrong with yours, your mileage may vary.
