the honey bee cp2 comes with Li-Po as stock. a brushless motor for the e-sky costs, like, 20$
so i guess the upgrade will be cheap....
i got heat sinks for tail motors, and i got 3 tail motors, so replacing them won't be a problome, they cost practicly nothing.

i live in a place where most of the time there's no wind/only slight winds
so i guess i'll stick to e-sky
