We are working on next generation of VTX8, but probably wont be ready til the outdoor season....

Electronics are strange things - we have a lot of people running it with out issue as well. We tested the software for about 6 months with a variety of different level drivers.... as long as a61 works for you. Like I said, on the VTX8 biggest different between a61 and a64 is the error detection program. On the VTX10 series - there was updates plus the error detection.

No if you remember I bought a brand new viper vf445 and still got the same error after 10 seconds on the track. (it happens with 3 different motors,4 different sensor wires, 2 different batteries and a new set of bullet connecters on motor and battery)Viper drivers are the one's that told me A64 doesn't play well in some esc's. There a several people who have had the same problem, they just run a61 with No problems

do you only get the error code when using a certain motor with that esc? biggest difference between a61 and a64 is the protection software. This protects the esc from outside shorts that could damage the unit (single biggest failure reason found with VTX8). If it keeps happening with that one motor - it could be something in that motor. Also we have seen a loose connection (or dirty connection) on the battery side cause a arch that the esc measures as a short. It is possible that one unit is more sensitive to the measurement than others, but shouldn't have the same issue with different motors.

I purchased two smc 7200 70c lipos and it completely corrected all my problems.
I went to a long day race day last weekend with absolutely no issues.

boborc - if the lights are alternating, its the motor error detection. If they were flashing together it was the motor/esc temp cut off. Make sure the cut off temperature is 60-90* higher than the outside temperature you are looking to achieve. As the protection settings read temperatures off the inside of the motor and esc. Example I would guess maybe your protection setting is maybe 200 area, based on what you put in the letter. This can cause the system to stutter because its warning you that your closing in on the temp cut off setting. Its just a layer of protection in the system. Nick/Viper
