Hm, interesting you say Hobao edition... Let me explain... HoBao make the buggy, and distribute it in Europe and the Orient, as a HoBao Hyper 7. In America, HoBao have a distributor, this is OFNA (they are also Hong Nor's distributor), so where you see a HoBao hyper 7 in europe and an OFNA Hyper 7 in the US, they are the exact same thing, sometimes with minor differences in what is supplied with the RTRs.

So, in simple words, you have a HoBao Hyper 7...do you know what model? PBS, PCM, TQ? There are many, and this will affect whether or not it is a good price. You also don't mention if it has radio etc? I'm assuming not, but again,t his would affect whether it's a good price. I would say that for a basic Hyper 7 rolling chassis, no radio, no engine (a shot engine is non engine as far as I'm concerned! lol!), that seems a bit expensive. As for engines, you have a HUGE choice. It all depends how much you want to spend...do you have a budget in mind?
