I agree with that. Well i just got off the phone with a traxxas tech. the 5309 is the same as the 5308 revo but this one has reverse, extra glow plug, different tires/wheels, rechargeable receiver pack, rechargeable ez starter 6 cell 15oomah pack, charger, dual steering waterproof servos 2075 servos, new body, a 2.4 gzh radio system and it includes all the same options the 5308 has (it has the extend chassis). They were just released and have not ship yet but will very soon. Ball park they will be around $540, all you'll need is fuel and 8 AAs for the radio.
