S411FF – Introduction
- Serpent S411FF -
The Serpent 411-FF is Serpent 1st ever front wheel drive only car. Its based on the highly successful Serpent 411 TC 4wd car and shares many parts.
Serpent has tested the front wheel drive cars intensively, and achieved a perfectly balanced race-chassis, putting the front mounted motor as low in the front as possible. The front whele drive system gives a unique drive-feel, very different from 4wd, but supersmooth, easy and great fun. Its actually much easier and nicer to race, than people think at 1st. Once you tried, you are hooked !
The FWD class is very big in Asia, and is gaining popularity around the world. In some countries it almost absorbed the stock-class.

Description
Serpent 411 FF front section
The front section is machined from 7075 T6 aluminium which hold the front mounted motor securely and as low as possible for optimal center of gravity.
The alumnium parts and carbon shocktower create a very strong assembly to stand the brute power of the motor and form a strong basis for the suspension.
Suspension front and rear
The 411 FF uses medium type suspension arms, c-hubs, uprights and steering blocks. Optional ones in soft and hard version can be tried too.
The front and rear uses machined aluminium suspension brackets for a super stabile and smooth drive. Shims are used to change wheelbase. The strong spring-steel pivotpins pivot on steel balls captured in the suspension brackets for supersmooth action.
RCM shocks
The 411 FF is fitted with the latest RCM Serpent shockabsorbers with coated alu shock-housing, stabile or-ring/shim package, rubber rembrames and precison made pistons.
Bodymounts front and rear
The long version flexible bodymounts suit the higher type bodies used in FWD racing. The 411 TC type bodymounts also fit the car as needed to use a lower bodyshell.
Shocktowers
Shocktowers front and rear in 2.5mm carbon fibre, with front 3 and rear 6 mounting holes for the shocks.
Chassis / topdeck
Cemetrical high quality carbon fibre chassis in 2.25 mm material, lowered to mount the battery tape below the chassis and carbon fibre flex top-deck in 2mm.
The Lipo pack is held in place with nylon brackets front and rear, and to the side as well.
The alu steering-servo mounts allow installing most commonly used servo's.
Steering
Ball raced dual axis steering system in durable aluminium with adjustable ackermann through shims.
Front differential
The compact and light front gear-differential is powered through 2 smaller central gears, which connect to the spur / motorgear.
Front drive and wheel adaptors
The front spring-steel CVD driveshafts are very durable and light. Same material is in use for the wheel-axles as well.
The hex wheel-adaptors are made of durable and light aluminium.
Anti-roll bars
Front and rear wire-type anti-roll bars. The anti-roll bars are pefectly centered and hold in place with nylon holders in the corrrect size. The anti-roll bars connect to a pivotball on the suspension arm. The length of this can be adjusted easily from the bottom with a hextool.
Serpent 411 FF kit
The 411-FF kit comes as racing chassis and does not include electronics, tyres/wheels, body or radio.
The kit comes in a strong compact carton box with parts packed in nylon bags per assembly step, as indicated in the full color manual. 2 pcs of body decal-sheet are included as well.
