I was thinking of getting one of these for my XXX-T, but first I need to build my brushless/LiPO LST2, would this 7700 brushless system work good in an lst2 with a 4000mah 4 cell 14.8v?

the 7700 is only good with 2 cells for Lipo.
5700 up to 3 cells.

I've run mine on 3300, 3800 and 4200's.
All were plenty fast, but the bigger the better the punch.

You need to check out the Mamba Monster Max, it is for this style of vehicle:

I must say that the MAMBA MAXX is impressive. I used the 5700 motor with my old GP3300 battery and it's still going ballistic. In a small asphalt track, I geared it at 9.86 it perform great although I can gear it further to gain more speed.

The throtle feel is smooth and no lag at all. With the old batteries, I can only last around 5minutes with a brush 23T motor. With MAMBA MAXX, I ran about 8 minutes. The motor heat is just nice.

Wondering what pinion/spur to use on a 5700kv with lots of wheelieing torque and fast but not too fast top speed, still like wow when tapped out though.

I just order the 5700 unit for my TC......

I wanted to run near 19T speeds, has anyone retarded the timing to get near 42000 RPM? as I plan to run the brushless during practice and then pop in a brushed 19T to race with as the locals still haven't caught on that Brushless is the future...

I knew one Castle Creations got rid of the cogging effect that it would be the system to get...TOp notch quality..
I am going to request that they add a RPM timing feature in the ESC software as that would probably make lots of peeps happy as from what I have read about the 5700 is that it is about a 9-12T in a TC and a 6-9T in 2wd buggy...
I am excited to play with the software...(side note = favorite feature of the Mamba 25)..

Plus I was waiting for a ESC that was sized down to fit in a TC comfortably...
I think I will be happy.....

I put the 7700 and Mamba ESC into my FTTC4 today and went to the track.

the footprint of the ESC was identical to the Novak GTX and cap that i took out.

I need a bigger spur gear, couldn't move the motor close enough to get the gearing i wanted with a 72t. the can on the Mamba is bigger than most. I also had to file out the chassis on my BJ4 when i had it in there.

I've been using the low power, so I guess i've got retarded timing

got ESC over 200 degrees, no thermaling. motor peaked at about 195.
gotta gear down for sanity if nothing else.
