- Team Associated B5M - Ray Munday - Setup Guide -


This setup guide has been created to give a starting point for typical track conditions experienced in Australia (dry, dusty, bumpy). Use the 'Standard Australia Setup' as a starting point, then make adjustments to suit your track condition.

  Standard
Australia Setup		 Low Grip High Grip Very Bumpy Carpet*
Front Suspension Shock Mount Top/Bottom Middle/Outer         Usually leave in this position.
Camber Link Tower/Hub Inner/Inner         Very rarely change. Lengthening gives less initial response, more mid/exit steering.
Washers Inner 2mm 1.5mm       Less washers (higher roll centre) gives more aggressive initial turn­in but less mid corner. Good for slippery tracks.
Camber ­1 deg ­0.5deg ­1.5deg ­1.5deg   Less camber = more grip but less forgiving in bumps. Very sensitive adjustment for bumpy tracks.
Kickup/Castor 25deg/30deg         Usually leave in this position.
Washers Rack/Outer 1mm/0mm   2mm/0mm     Sensitive adjustment. Less washers on rack gives more initial steering at low speed. Good for hairpins
Axle Height Medium (Kit)         Not tested
Trail/Hub Spacing f/r 4mm/2mm Rr 3mm/1mm Fr & Rr       Less trail gives more reactive steering on entry.
Toe In/Out 1 deg Out 1.5deg Out       More toe out gives more steering on low speed turn in.
Arms Flat (Hard if hot weather) Gull (Kit) Plastic Hard arms, hubs, front brace   All hard parts Flat arms = smoother steering. Gull arms (kit) give more low speed steering feel. Hard front arms make steering much more precise and smooth in high grip/high temp.
Ride Height 24mm 25mm   24mm 18mm 24mm used most of the time. Higher ride height = more traction on slippery surface, but more chance of traction roll on grippy surface.
Spring AE White AE Green AE Grey AE Green AE Red AE White most of the time. Use Grey to smooth out steering in very high grip. Green for more steering and smoother in bumps.
Oil/Piston AE 40wt/1.7mm (32.5/1.6 if smooth) AE 37.5wt/1.7mm AE 35wt/1.6 AE 37.5wt/1.7mm AE 37.5wt/1.6mm 1.7mm pistons ride bumps better and give more traction feel than 1.6mm pistons. If temps are cool, drop 2.5wt. Use 1.6mm pistons if track is very smooth and becomes 'aggressive' traction.
Limiters/Length/Rebound 2 Limiters/20mm rod/3mm rebound     1 limiter (20.7mm rod)   More limiters gives flatter/more precise steering, but can limit grip in low traction. Usually use 2 limiters.
Rear Suspension Shock Mount Top/Bottom Inner/Inner   Middle/Inner   Middle/Inner Always use inner hole on arm. On tower, inner hole gives more rear grip in sweepers and bumps.
Camber Link Inner/Hub Inner/Middle (Rrinner with alloy hub)         Very rarely change. Longer link smooths out traction on high grip tracks, but not necessary on this car.
Washers Inner/Height Outer 1mm/Up (3mm outer with alloy hub)   2mm @ Inner     Less inner washers (higher rear roll centre) gives more steering at mid/exit. More washers (lower rear roll centre) gives smoother rear grip.
Camber ­1deg ­0.5deg ­1.5deg ­2deg ­2deg Less camber = more grip but less forgiving in bumps. Very sensitive adjustment for bumpy tracks. Use more camber for high grip to reduce traction roll.
Anti­Squat 2 deg   1 deg   1 deg Usually use 2deg for Australian tracks. 1deg gives smoother side bight and better braking, but less forward traction.
Toe In (Inner/Outer) 3deg/0 3.5deg       Usually use 3deg. 3.5deg if need more stability on corner exit on very slippery tracks.
WheelBase Short (B5R Reararms)   Medium (B5M rear arms)   Long (B5M rear arms) Sensitive adjustment. Use B5R rear arm (gives ~2mm shorter wheelbase) in most conditions. Shorter wheelbase = more forward traction (better for most dirt tracks)
Anti­Roll Bar No   Green (If track has many sweeping corners)   Green Rear anti­roll bar keeps car flatter through corner. Makes car feel more 'locked in' through sweepers but at tight corners has less turn in/more exit oversteer. Only use for very high grip/flowing turns.
Ride Height 23mm 24mm   24mm 18mm 23mm used most of the time. Higher ride height = more traction on slippery surface, but more chance of traction roll on grippy surface.
Spring AE White AE Green AE White AE Green AE White AE White most of the time. Use Green if track is very slippery or bumpy. Typically use same spring colour front and rear unless steering becomes aggressive on high grip.
Oil/Piston AE 35wt/1.7mm (27.5/1.6 if smooth) AE 32.5wt/1.7mm AE 30wt/1.6mm AE 32.5wt/1.7mm AE 32.5wt/1.6mm 1.7mm pistons ride bumps better and give more traction feel than 1.6mm pistons. If temps are cool, drop 2.5wt. Use 1.6mm pistons if track is very smooth and becomes 'aggressive' traction.
Limiters/Length/Rebound 1 Limiter/27mm rod/3mm rebound     0 limiters (27.7mm rod)   Sensitive adjustment. Use longer rear shock (0 limiter or wind out shock 2 turns) if track is very bumpy.
Tyres Front Usually Rip or Bar Code
(See Tyre Chart)		 Usually Rips
(See Tyre Chart)		 Usually Dirt Web
(See Tyre Chart)		 (See Tyre Chart) Stagger Rib Front: Typically JConcepts Rips if the track is damp, Bar Codes if dusty and Dirt Webs if grooved.
Rear: JConcepts 3Ds if hard packed but dusty/loose on top, Bar Codes if grooved, Flip Outs if wet. Blue compound most of the time, with orange if it is very hot and green if damp.

Drivetrain Motor Reedy Sonic 8.5T   Sonic 7.5T   6.5T 8.5T for most tracks.
Timing/Rotor 30deg 20deg 30deg 10deg 20deg Increase timing for more power feel and higher top speed. Reduce timing for better controllability at low speed on slippery/bumpy tracks.
Pinion/Spur 23/75 (24/75 if large track)        
Slipper V2 Vented VTS V2 Vented VTS V2 (Set to stop wheelstand) V2 slipper is less weight and more responsive. VTS (kit) slipper is smoother on low traction/bumpy tracks. For 17.5T, use slipper eliminator.
Ratio 8.48/8.125        
Diff Ball, Medium Tight   (Gear diff 3K oil if very grippy)   Gear, 3K to 5K Use tighter setting than for rear motor to avoid diffing out on corner exit.
Gearbox 4 gear   3 gear if very grippy   3 gear 4 gear transmission gives more forward traction and more pitch control in the air. 3 gear more on power steering and better braking.
Electronics Radio KO KIY EX­1        
EPA Brake 80 (Just stop lockup in straight line) Adjust to suit Adjust to suit Adjust to suit Adjust to suit Tune brake EPA to just stop wheel lockup on straight from high speed. May change from race to race ­check on warm up lap.
EXPO Steer/Throttle/Brake 0/­15%/0        
Servo Low Profile   Full size (add 10/20g on top of low profile)     Low profile servo is good for most Australian tracks (less weight on front) but requires some servo case modification to fit B5M servo mounts.
ESC/Fan Reedy Blackbox 410R Mount ESC further back if need extra forward traction       Mount ESC behind servo. If track is ultra low grip, can move ESC back and use shorty at rear for more rearwards weight bias.
Drag Brake 13% 18%       Increase for slippery track.
Brake Strength 83%        
DeadBand % 3%        
Drive/Brake Frequency (kHz) 16K/1.6K         Higher drive frequency smooths out power.
Advance/RPM/Max RPM OFF        
XTRA Timing OFF OFF 10deg if very long straight OFF   Use boost timing on long straight with good traction. If track is bumpy or slippery, I prefer no boost.
Battery Placement Rear Rear Front Rear Front Makes a big difference to weight balance. Battery rear = more forward traction, less on power steering. Battery front = more on power steering, smoother cornering and jumping, but less forward traction.
Battery Reedy 5700 Saddle or Reedy 4100 Shorty Use shorty at rear with ESC back if need extra forward traction Shorty if smooth Saddle Shorty Saddle packs make the car easier to drive in most conditions, but are less responsive for tighter tracks. For 17.5T, use shorty to reduce weight.
Aero/Chassis Body JConcepts Silencer
JConcepts Finnisher		 JConcepts Silencer JConcepts Finnisher     Body can make a big difference. JConcepts Silencer ­ smoother steering, easier to drive. JConcepts Finnisher ­ more aggressive steering on corner exit.
Wing JConcepts 6.5" Hi­Clearance         I use this wing all the time.
Wing Lip/Angle Line #0/Minimum angle         Sensitive adjustment. B5M wing sits a long way back and has strong leverage on car. If wing is too big, will jump nose high. Minimum lip and minimum angle most conditions.
Chassis/Fr & Rr Arms All plastic (hard front arms if >30C) All plastic. Loosen screws from transmission brace if need extra rear grip. Hard arms, hubs, front brace. Hard rear arms if very grippy. All plastic. Loosen screws from transmission brace if need extra rear grip. All hard parts. If temperature is low, use plastic parts. If temperature is high and grip comes up, use hard parts (starting from the front of the car).
Ballast Brass C block Brass D block 10g on rear tower if very slippery Alloy or plastic C and D block. Brass C block. Brass front bulkhead. Alloy C and D blocks. Sensitive adjustment. Very sensitive adjustment (key to making mid­motor work on all tracks): Use Brass C most of the time (adds forward traction and rotation). Use Brass D if need extra forward traction (but will lose on power steering) If very low traction, add 10/20g behind tower.
