I run both Orion and Speedpassion

I did have a capacitor blow on the Orion unsure why but I replaced it easily enough, the speed passion has been rock solid also.

Tuning wise the reventon pro is easy with the software.

The Orions differ depending on what Ampage you buy, the 160 A is very tweakable and lets you push the timings a lot. the 90A isn't as tunable.

I am also myself considering Hobbywing also, if you plan to go with lower turn motors for fun look at the higher Amps rates so your covered.

the orions have hard soldered wires, the Speed Passions you need to solder them
