I am new to heli's but have years in fixed wing gas and electric. Can the e-sky be upgraded to brushless? It does not appear that the speed control is seperate from the gyro unit. I do not want to spend the $250 for the 37E (+ more LiPos) but I do want to be able to upgrade to brushless (I already have speed controls for brushless) eventually after I break some parts.

Another question: Has anyone used the esky flight sim? Does it have the proper physics for heli's?

Raidentech (nitroplanes) has it for $20
