Agreed.I know for a fact that you cannot get the same torque on a Phillips head fastener as you can a hex head. Could you imagine if Arrma used phillips head hardware on their cars you would never be able to get them apart as the damn screws round out 90% of the time with hex hardware when you try to remove them. Phillips would be 100% of the time.
As far as usability, I prefer HEX. As far as torque and Arrma, if they didn't bathe each bolt in Loctite no one would have stripped hex issues IMO. As far as in general, if a bolt/fastener, Phillips or HEX, Flat head or TORX is torqued properly, there is zero difference other than its looks.
