Default Dynamite Fuze SC ESC/brushless problems

I was hoping that someone might have a suggestion for a problem I'm having with a new brushless setup for my son's Blitz.

I just installed a Dynamite Fuze short course brushless ESC / 3300 KV motor combo and I'm having problems with it "cogging" (at least I think that's what it is). I've gone through the setup per instructions and that all seems fine, it's just that when I punch the throttle off the line, it jerks and even seems to go in reverse for a split second. If I apply throttle gradually and get it rolling I can go full throttle without a problem. It's also running very hot just in the few minutes I'm running it down the street.

I'm using a Turnigy 2C Lipo that I have run in my SC10 and it works great, so I know it's not a battery issue. The radio is an Airtronics MX3 synthesized. I'm geared at 88 / 23.

Any help would be much appreciated.
Thanks

I went down to a 18T pinion just to see if it made any difference and it's still doing the same thing. I also adjusted the start-up power to the maximum- I heard that could help, but no dice.

On the timing- would I advance or retard it?

Thanks

To actually ANSWER your question, see the two posts above mine you will understand my intro.

You must retard, or turn down, the timing. More timing reduces initial torque in order to gain top end. However, too much timing can cause problems you are describing. Also, the Fuze system is sensor less, and as a result, may hesitate slightly when accelerating from a dead stop. Also, contact Horizon Hobby as far as gearing recommendations. Hope this helps.

I had this issue as well in my fuze . but it only happens after the motor is warm . so i geared it don as much as i could . this helped but not enugh to i installed a heat sink on the motor and now i have no issued with it , but turn down initial power and reduce timing . this setup has been working great for me and it is close to stock power of the titan .
