I am building an Align EFL Pro with the older Ver 2.0 and was going to upgrade to the 3.0 version but I was reading how the 3.0 needs more power and people were having problems with Helicopter sizes 550 or less. They were recommending
an upgraded ESC to around 90 amps like the Talon 90 which runs around $90. They were also recommending a separate BEC. Another suggestion was turning the pots down but some people were having problems even with that. There is a whole discussion of it on Helifreak. Click on the address below.
3GX 3.0 power and gains on 550 and smaller helis - HeliFreak
Even though some people were having no problems others have had browns outs which makes me just want to stay with the 2.0 version.
