Its not capable of supporting a heavy SC truck, regardless of the motor you choose
Use the SV2 in the MERV
If sticking with 2s the 3800 or 4400 will both do the trick
Great bang for buck combo
Gearing depends on what version of the motor you are planning to get, what voltage you plan to run, and what speed you want
2400 will happily run 4s if you gear the car correctly (50 mph for bashing, 60 mph for speed runs)
Use the following settings in your ESC
Start Power - High
Punch Control - Disabled
Timing - Zero
Centre your thottle trim
Set your throttle / brake travel (EPA's) at 100%
Calibrate the ESC...
What battery are you using ?
What are your ESC settings ?
What is your gearing ?
SCT Race Pro combo (1410 3800kv motor) will not do 60 mph
The 1415 2400kv will do 60 mph on 4s
The Mamba Monster (2650 or 2200kv motors) will both do it comfortably
Gear ratio is simply Spur divided by Pinion, smaller the number faster the car
12/54 = 4.5
Stock 13/54 = 4.15
14/54 = 3.85
Generally speaking ........
Smaller pinion / larger spur =...
Basic Ohms Law (V=IR)
Those that do not understand it, should be running similar specced packs in parallel
Lots of incorrect info in this thread suggest most of you do a lot more reading before handing out advice
Lipos shoul never be stored fully charged
Their internal resistance will slowly rise over time
When not in use they should be at 50% (3.85v / cell)
If you are talking about the servo lead they are ....
Black - negative (ground)
Red - positive
White - signal
Bypass the internal bec (remove red wire) and throw on a receiver battery if you...
If the receiver powers up then the MMP internal bec is fine
Sounds like your servo is stuffed
Will feel a bit sluggish at 30 mph on 3s, but should work fine
Pretty easy to work out a speed change when changing a pinion
Assuming stock is a 13 and you are moving to a 14
14 divided by 13 = 1.07
7 % speed increase
And if we use a 15 .............
LOL @ paying more than $100 for a 70c (not likely) 2s lipo pack
Plenty of options around for a lot less money around
Punch control does nothing to save your drivetrain, it simply delays the application of the throttle signal
Sounds like you need to learn throttle control
If you want less torque to protect...
1 - Default
2 - 50%
3 - 100%
4 - Disabled
6 - Default
7 - Auto lipo (3.5v / cell LVC)
8 - Zero (0)
9 - Smartsense
Start with ............
LVC 3.5v / cell
Punch and Torque Limit disabled
Zero (0) Timing
Why run 2s packs in series, just buy a decent 5000 mah 40c 4s pack
17/52 is far too high
Start with 12/54 (34 mph or so) and monitor your temps
Motor voltage limit (listed on the can) has nothing to do with castle suggested use in a heavy SC truck (3s or 4s)
5s would only be 50,000 rpms and the Neu based motors are good for 60,000
2200 will be capable of any speed between 40 and 90 mph
What voltage do you plan to run ?
What speed do you want ?
Metal Mod1 spurs are not cheap, you dont really need them, stock spurs with...
A motors kv rating has no relationship to the power it is capable of making, it is simply a measure of how fast it will spin when applied with a given voltage
Decide what voltage you plan to run...
Dont need the driveshafts depending on how hard you drive, everything else yes
