Future plans for a TC3 BL

[havy]

I have some plans to go Brushless on a 1:10 scale level. I have some experience running BL micros but I want to run a fast controllable 1:10 scale car.

My plans are to run a TC3 at 200mm w/ outlaw body at the local track. My goal w/ the set up would be to be up to a 45-50mph car top speed (I think that would be plenty) and at 200mm I would imagine I would still retain good cornering abilities.

Now what I'm not so sure of is the motor batt combo for such a car. Running Lipo's, would I be too light to maintain cornering ability? What voltage Kv combo would be most optimum? I have read Optiman's post, very interesting points guys on motor efficiency, vs Kv w/ batt voltage.

Any ideas, this is brainstorming time for me... going to take my time to decide how I want this done....Run time... at least 15 min would be optimum if not more.

How long do Lipo's take to charge? say 11.2v 4000 mentioned earlier.

Thanks,
Havy

An 11.1 volt 4000 mah would take 1 hour to charge from a complete drain (which I rarely need to do). It also depends on the charger - some chargers can only charge at 1.25 amps, some at 2.5 amps, and the Astro Flight 109 can charge up to 8 amps and 8 lithium cells in series. Most LiPo packs are charged at 1C (1 x capacity).

A TC with 11.1 volts and 4000 mah is roughly equivalent to running 7.2 volts and 6000 mah so 15 minutes is definitely not out of the question. With speeds in the 40-50 mph, you'll want a motor around 4000-4500 rpm/volt so with a FDR of 6 or 7:1, you'll be in that range. Getting a slower motor, you would need to go higher voltage.

A Hacker c40 8-10 turn would be great
A Basic 4200 would also be great and real cheap.
A Lehner 15xx series in the 4000-4500 rpm/volt would be great too - but you would need an adapter plate.

Thanks, I aappreciate the input:) .
