ya, my son is 6 too and likes playing as a ba or aero.. now his aero skills amount to crashing into an enemy mech if he is lucky.. ejecting out if really lucky..
he plays as my whitedrake, but I'd doubt you'd notice the differance between our play i'm so bad..

hahahah
his new ''trick '' is running backward looking back toward his base, hitting his JJ and firen' his ppc for extra distance.
i wonder if the ac2 would give him more kick distance.
