Rather it is the Velociti 5.5R motor that is getting the thermal issues even when using the recommended FDR or higher.
On the other hand, I have used the Nosram Storm 3-Star motor (which I reckon is similar to LRP Vector) with the GTB and it is certainly able to withstand a much higher temperature. Unfortunately for 2 friends of mine at our club, the temperature apparently got too high and their 3-Star rotor magnet cracked during the last minute of 7mins heats. They broke 3 motors in between them.
Also for this 3-Star motor that I got, one of the three 1.5mm screws securing the endbell was bent out of shape within when I disassembled it for my first maintenance. I am not sure if this was due to the result of use, or a factory assembly problem. Anyway, the Velociti is certainly more robust in design, although heavier.
I would like to try the LRP Sphere Competition when budget allows, soon I hope.
yes...more constructive discussion is better. But the one u were talking about is not a LRP ESC and is not even a comp. version. I know there are some bad reports about the older version, burnt or not enough power / fast as the 5.5
but are there anymore feedback from the SPHERE COMP. VERSION? TA
