Several questions

[JB3231]

I sold my brushless LST2 several months ago as it was just too much.

I have my sons Emaxx right now. We have been running a MM ESC/5700 & 3S Lipo 4000 Maxamps for a while. The setup came out of my B4 for fun one day and it ran so well it's been in there ever since. I've got it geared as low as I can go 10/72. It run's good on(2) 6 cell Nimh packs and very fast on the single 3S Lipo.

I was running 5s on my LST and the Maxx is not nearly as strong. But I'm not looking for that anymore.

I thought about going to the HV-Maxx 4.5 but it's kind of $$ when I already have a great ESC with Lipo cutoff. If I go Lipo I want to use my existing pack and maybe purchase one more identical and use the MM ESC built in cutoff. 2 packs parallel 3S 4000 = 8000MAh = long run times and built in Lipo cutoff.

If I bought one more 3S Maxamps pack and ran them parallel what motor would I want. I looked at the Feigao 7XL, 8XL, 9XL but the KV seem kind of low for what I want. I can't find any info on the L size cans.

The 5700 is nice but I can tell it's really not meant to push a monster truck around. The XL motors are very cheap and would be an easy upgrade.

I would be going from 5700KV/V to 2400Kv/V on the 7XL.

What do you guys suggest?
