RE: A123 Batteries for Pattern Rx ?
Update
I have been using the 1100Mah A123 battery pack on my 2m pattern Rx for about 1 month now. On my Osmose I have 2x9154, 2x9551, 1x9350, 1x9602, duralite 5.2v Regulator.
The plane consumes 90-120Mah per flight (11mins). Out of habit i charge after 2 flights and it takes ~200-240Mah. You could probably do 5 flights safely per charge but I havnt tried it yet.
If you are getting the FMA Cellpro 4s balancing charger make sure it has the new v3.02 software as you cant download an upgrade.
So far I am very happy.
