Yes, $175.00 is great price for this plane... (in the UK, it is <span style="font-size: small">&pound;143.20 =$218 </span>... - http://www.bondaero.co.uk/product/monolog70 )
-I have Monolog 110, love it ...

For this Monolog 70, NODOUBT ABOUT IT: I would use <span style="font-size: medium">Turnigy SK3 5055-320kv (369g)orGens ACE Mars BL4850-340KV(370g)</span>
-with 6S LiPo
-These two motors are almost IDENTICAL to Hacker A50-16 S motor -but cost only $49, 1/3 the price of the Hacker.
-Except they have a 5030 stator and they will be more powerful than the Hacker
-These 2 motors are identical to each other
-And are made in the Sunray Tech factory along with Hacker, Torque, Z-Hyperion;and LiPolice, OK Hobby Infinite, Shulman Aviation FURY,Common-Sense-RC etcetc etc

-And I would also use a Turnigy dlux 80A ESC -which is also made by Sunray Tech -and better than a Hacker or other ESC ... and is only a fraction the price ...
