Brushless Savage Setup

With the the automatic transmission I loose the reverse gear...

If you plan on running 2nd gear, i would use the 8XL.. (with a 16/49 gearing it is really quick (40 mph))

Which "heavy duty 2nd gear mod" do you mean?

2nd gear fixed could be an option. But with an 8XL on 16 cells I am always below the sweet spot (~33000 rpm). Something to care about??

The more I play with the speedtable the more I like the BK 20XL/7 or maybe the BK 20L/10. The L of course draws less amps, which means longer run time. But is an "L" strong enough for a Savage???

BTW: Why does a Feigao 7XL has a kv of 2382 and a BK 20XL/7 a kv of only 2145? I thought that they are more or less identical...?

OK, when you have to choose one of these setups, which one would you prefer? (always on 16 cells and with a BK 12020 controller)

a) BK 20XL/7 (kv: 2145, about 90-95 amps)
b) BK 20L/10 (kv: 2212, about 60 amps)

Speed is for both setups nearly the same:
1st gear: 16/49= 30 mph or 18/49 = 33 mph
2nd gear: 16/49 = 42 mph

Again: is an "L" strong enough for a Savage? And does it has more torque than a stock .25 nitro Savage?

Thanks!
