they will start both and in fact after a while u dont need the pegs u just know where to land the car to bump it. admittedly if u dont have 1 already. it seems that there's been a rash of QT probs w/the boxes shredding the small gear reduction pulley. mine 2nd box shred on 1st hit crazy stuff. horizon sent me the parts but while waitin i went and bought the truggy box from ofna. honestly i have yet to put the RTR box back together w/the correct parts. likely just offload it for a race fee to a friend who could use the box as backup to his losi box.
food for thought if u havent purchased yet.
