there are alot of those coaxials around by brands ... the most popular one over here is ESKY i think
u can find them almost everywhere .. the V3 i think can get around rm250 or so ... the V4 looks much nicer and only costs rm280 ... hehehe
surprisingly there is oso AZTECH making them helis now .. the coaxial azteh can be found for as low as rm220 if u look around .. but with plain white canopy and body ... nothing visually fancy but it works just the same ... hahahahaa
in fact u can paint it to whatever color scheme u like oso

other than that ... if u plan to get into the heli scene .. there is nothing better to get u started and interested than coaxials coz the others will be much harder to learn and u might give up much more easily ... huahahaha
get the coaxials and a couple of spare batt for more flying time ... welcome to the heli world
