I realize this depends on my electronics so here's what I'm intending to put in the car in case it helps:
- VTX10 ESC
- Futaba R603FS receiver
- Futaba S9551 servo
- Older/classic AMB transponder
- Motor not sure yet but these don't vary too much in weight I imagine
- Battery: as much capacity (with high C rating) as I can do without putting more weight on the battery side than the other side.
I guess I'm wondering:
1 - Can a high capacity lipo cause the battery side of the car to be heaviest? Or am I almost guaranteed that the battery side will be light than the other side regardless of a 4000 mah battery versus 6500 mah for example. I'd be looking at the higher end Reedys.
2 - What about minimum ROAR weight - do you think the higher capacity battery would put me over the min or will I still tend to need weights?
Thanks all, I can experiment but I'm hoping to not have to buy two $100+ batteries just to find out!
PS - I realize that keeping weight lower is better. So a lower capacity battery plus weights is better than a higher capacity battery and no weights. However, I'd prefer the higher capacity for longer run times. I also realize I'll use far less than even a 4000 mah battery per run but for me, bigger is better for more practice time.
Almost everyone runs a 6000+ battery, your left/right balance is closer as is min weight, to meet 1380 you might need 10-20g here or there, I don't know the exact weights of your stuff or the T4 unloaded. The VTX is on the heavier side though.
