Serpent S411 Test Run

Received my S411 on Sat and completed all build on Tue. Have 2 packs of test run on Wed.

Here is the basic setup of the chassis :
Front gear diff (500k wt) / Rear gear diff (1200wt)

Shocks oil F/R Yokomo 450wt, Springs - stock
Change to harden a-arms all around, and also place 2mm collar in front of rear a-arm along the inner pin to lengthen the wheel base.

Camber -1 all around, Sorex 40R with Yokomo 039m inserts.

Ride height F/R 4.6mm/4.8mm

ESC - Viper VTX10 with 10.5 motor, gear at 22/84T.

ESC profile #7, with the following changes :

PWM freq 8k

Boost start/end RPM 9k/18k

Boost degree - 24 / Turbo degree 30 / Turbo slope 15 degree per 1,000 rpm

Voltage cut off - 6.6v

Temp protection ESC/motor - 220F

Started testing at around 615pm for first pack and around 7pm for 2nd pack. S411 has lots of steering and overall very stable. ESC was at around 50C and motor at around 70C after 7min of run time. Need to fine tune futher for more top speed and more steering when acceleration, also found that the front springs (orange) are a bit too hard.

More testing to be done this coming Sat !
