I admit it does not look as cool or solid like a 4Pk or an M11x.
But I like how it's lighter, cheaper and has all the features.
I thought about trading it for the others but couldn't.
Spektrum DSM2 rx's are also cheaper than the other brands.
I never had brown out issues. I did have issues with using Savox servos but all those issues were fixed by using a capacitor.
+1 for Spektrum.
At the end of the day. They all work. Pick your radio and race
