I was going to post a video to show my problem with my reventon pro 1.1 but I can't seem to get it to work. A little history, I bought my first speedo motor combo about a month. My first speedo had a hesitation during initial throttle input (kind of like a cogging). I tried different motors, several sensor wires, changing from mod 2 to mod 1 software, and even different brand radio and receivers and nothing helped so I sent it back to get warrantied. I received my new one just in time for a long race weekend. What do you know the exact same result. I am baffled. I have a hard time believing that both of these are bad. I have reset my throttle points I don't know how many times and have played with my neutral point adjustments with the programming box thinking that was messing with it. Has anyone had similar issues?
FWIW, a friend of mine mentioned that it could be related to the savox servo im using. will try another servo and see if the problem disapears.

Yes, I do have the current software. I was using the same esc in another car running the mod2 firmware with no issues. I think its just an issue with that firmware/motor combo.

I have the same combo, and experieced the same problem. I replaced the sensor wire, and that corrected the problem. You have to make sure the sensor wire is firmly seated in the esc. I will actually shoot a little bit of motor spray into the socket, blow it out with air, and after inserting the sensor cable I'll use a jewelers screw driver to make sure it is fully seated. I've actually had to replace the sensor cable 3 times. Once, only a couple of weeks after having replaced one. They have all looked ok. I've switched to a flat stiffer cable, and so far it has been holding up.

Maybe so Ron. I run all SP motors and have never experienced anything like that. You try another brand motor to confirm?

I have a Speed Passion Reventon Stock Club Race and V3.0 17.5 combo in my Tamiya buggy. I was looking at the USA website and it showed the v3.0 17.5 as 2700kv and the MMMas 2900kv. The paperwork I got with my combo shows the v3.0 as 2200kv. Was this a running change? Or was my motor underrated? What can be done to achieve that 2700kv on my motor? I'm running 33/69 gearing and my temps are at 130 on the motor. So I assume I can gear up a little? maybe try 35?

Had my first time running stock and I would call it a success. Bigron was nice enough to load the firmware onto my Revention R, thanks again, and I ran my 17.5 with stock can timing. I was horribly under geared but still made decent lap times. I am planning to run again Saturday at the WRL race and hopefully my gearing will be better but I still will be running with stock can timing. The new speedo ran great and I have no complaints. A friend told me he runs 37/69 on his B4 so that's where I at for Saturday. Thanks SP.

anyone thoughts on the SP 7.5 v3 Comp NON mmm motor? heat issues? durability? I am sure its plenty fast, because its an 8.5, lol. The motors are just sooo cheap... I have to try mod. I might use this for 4x4 buggy in the future as well.
