I always thought the H7 RTR came with the normal Hyper 21. I as looking through an issue of RC Nitro with the buggy article and it showed the RTR with the 8-port. Which engine comes with it stock?
from what I've red hobao have released 4 or 5 versions of there hyper buggy, the basic rtr kit comes with radio gear and 4 port, then you can buy the car unassembled with or without engine. and also theres the rtr kit with the 8 port, radio gear and starter box.
kuma hit it on the head. previously on the PBS version came with the 8port, however - all the new hyper 7 kits, even the RTR version are now coming with the 8port. but it does include a black head, which can be very confusing
