I've been running a 1600 and 1900 nimh hump packs. I've never had any trouble with them, but I've entered my first big race and I'll probably be in either a 45 or 30 minute main.

I'm adding a 7955 servo and an rc4 transponder to the mix. Both are going to use more juice then what I was using before. Am I going to be able to run long mains with just normal Nimh packs, or am I going to have to make the switch to lipo? I really don't want to switch, but if lipo is really needed I can.

And if I can stick with Nimh packs do I need to go bigger then 1900?

no need to switch. if you have a fresh nimh for the mian you will be fine.

That's what I wanted to hear.

They should last. I just got a Reedy lipo pack. I ran about 10 min in practice then 3 qualifiers and decided to top it off before the main and it only charged less than 400mah. It's nice having the lipo in there. You might want a regulator as well.

If I went lipo what all do I need? I don't know anything about them.

You'll need the lipo, a regulator and a compatible charger. I use a common sense rx battery and the reedy regulator. I have 2 hyperion charges that i maintain all the batteries with.

Is this all I would need to go lipo.

I wasn't sure about a bag, but it seems like I read that tracks are starting to require lipo charging in in a bag.

Those are what you need. I'm not sure about the bag for the state race. I haven't heard anything about needing them. But that lipo is good. Muchmoore has a regulator for 15 bucks. Little cheaper than that losi one.

this one. I have it works good.

I dont use a bag for the rx battery since i charge it in the car. Most of the time i charge the nite before. i use this regulator.

That's the one I looked at but it's out of stock. I hate to mix a losi regulator with an associated battery. Losi might try and sabotage me, but that's the only other cheap one I seen.

you can still run nimh, can switch to lipo or run LIFE which is probably better. your choice of course.

I run nimh and ran a 30 min main with a fresh 1600mah. No Problem. Using JR 9100s and T and an amb transponder.

I'm just kind of checking out my options, and seeing how much it would cost to make the switch. It's looking like it's a pretty expensive switch. I'll peobably stick with what I have for now. Maybe do some testing this weekend and see how long i can run non stop before my 1900 dies.

Make sure you have a strong throttle return spring if you are going to run it till it dies!

If you're running dual 7955's you can run unregulated lipo. Unless you're running the FASST radio system.
