Default 5 Cell Hump or 5 cell flat?

i'm trying to find out what is better for my ntc3 reciever. A 5 cell hump or flat 5 cell? Also, where can i find on with the most power and what kind of charger should i get? I am going to be running a 2 hour endurance race and i need LOTS of battery power with a fast charger. what do you suggest?

get a flat one because it has a lower CG

and if you need ur batteries to last long

i would charge it at the slowest rate possible

you can solder them with a sodlering iron

then you need to buy the plugs and heat shink


and maybe a super brain charger

Here's an idea for the enduro race.

Set up two AAA packs or AA packs with connectors. Or use two flat 5 cell receiver NiMH packs of 1000mah or >.

Install them both in the car, one under the radio plate and the other on top of the plate. You can use the same wire tie.

Attach the female connector of an aileron servo extension into the receiver and run the male end out to the batteries. So you can switch battery leads without removing anything.

Now all you need to do to switch batteries is to unplug the spent one and plug in the fresh back up and you're out of the pits in about 10 seconds or less.

Yeah, didn't I mention any NiMH with 1000mah or more?

Use a trickle charger if you don't have access to a peak charger but it will seem like it'll take forever to charge two packs. About 20 to 30 hours per pack.

If you can use a peak charger that handles Rx packs and NiMH then you can charge a pack in about two hours at .5amp.


If you don't have access to either then buy two 4 cell AA holders with connectors to fit the servo extension and just swap them as I described. They may only last for a half hour per set but it's a lot cheaper than buying two Rx packs and a decent charger.
