B4 with Li-Po

[V-Rossi]

Hi,

I want to use Li-Po's in my B4 (Orion Platinum 4800), and use weights to have the same weight as with the use of Ni-MH's. I want to drive Li-Po because it is very easy and cheap when you keep the lifespan in mind.
Is this a good idea and will it give about the same driving characteristics as normal? I'll use it with a LRP Sphere Competition TC and Orion Vortex 6,5 motor.
