The 900 is prob going to be delayed again due to problems with the main blades, but it is a 500 size heli, 550's use 550mm blades (I didn't come up with the class'
) IMO ESky waiting too long to release this heli, currently there are something like 16 different 500 size helis already available. And HobbyCity in China just released the HK-T500 for $55
and thats a T-Rex 500 clone. ESky needs to concentrate their time and energy on getting the E-Smart back into production like they said they would.
Here is the new HK-T500 that is only $55
