RE: Colco Lama IV
man o man, i have 2 of the 2007 colco lama iv's. they are great. very smooth and stable. and man are they tough. they also seem to run much cooler than the 2006 model.however the battery is not 1000 mah as advertised. i still use them though. i bought a venom ven-1568 20c 2s 800 mah replacement lipo for $24.00 that nearly doubles my flight time, and its not even broke in yet!! get one you wont be sorry!! my buddy bought a well known $210.00 coax heli that i wont name, and man were we shocked to see how solid these colco's are compared to that flimsy thing that uses expensive junk proprietary blades!! these babys will take blades from several brands such as esky lama v3 and v4 venom ocean rescue, walkera 5/4 and just about any other coax heli blade. and the motors are $4.00 each and run forever. but with a little cutting several other coax motors will also fit this heli. get one!!
