My RC10 (runner)

[R16]

I changed a front toe angle (to slightly toe out), then I feel that the car is very much dialed. I will try ASC #27.5 oil for the rear shocks next time.

[EDIT]
Instead of changing the shock oil, I compared three different weight settings (adding 0g, 5g or 10g weight right by the servo) to check twitchiness. With 10g weight, I felt that the car was dull. I think that 5g is best and am happy with this car.

RC10 Laydown Ver.3

I adopt front and rear suspensions from ver.1 (page 3) and chassis from ver.2 (page 5) and run this car on outdoor dirt and indoor clay tracks.

<Front>
Same as the ver.1 (page 3), differences are
・V1 big bore front shock body (23mm), gray V1 spring, 1.6 piston ASC#32.5 oil
・Shock positions: Center hole on the arm and tower
・Front camber link: Center hole on the shock tower and outer hole on the hub carrier
・Custom Works 5deg caster block (-5deg)
・Stock inline steering block

<Middle>
Same as the ver.2 (page 5), differences are
・From front to rear: radio receiver, ESC and 10g weight below the capacitor
・10g below the battery near the motor cooler

<Rear>
Same as the ver.1 (page 3), differences are
・V2 big bore rear shock body (31mm), gray V1 spring, 1.7 piston ASC#30 oil
・Shock position: Outer hole on the arm and lower inner hole on the tower
・Rear camber link: Inner lower hole on the bulk head and inner hole on the hub carrier (1.5mm spacer below the ball stud)
・The shock tower, body post, and additional spacers and washers on the transmission case are same as ver.2 (page 5)
・Kyosho RB7 wing mounts

In the video, the inner higher hole on the bulk head and 2mm spacer below the ball stud on the rear hub carrier are used (more roll). I feel better with the current setting (less roll by using the lower hole).

[R16]

<RC10Mid Ver.2 Final>

I felt that the car bounced too much. I changed the rear shock oil from ASC30 to ASC27.5 and added weights shown in the picture below. Then, the total weight was 1562 g with a thin shorty Lipo battery.

Please see after 1:12 for the new setting.

After this video, I removed 10g below the pinion gear to make the car quicker.

It's definitely way more stable with the lighter oil. Do you have any video of it with the 10g removed...?

[R16]

Thank you for your comment. I did not shoot video after removing 10g... I added weights and used the lighter oil to stabilize the car on bumpy surface. Those worked well but the car lost agility (spread weight distribution), turned less in corners (increased rear grip and rearward weight bias) and needed longer distance before the jump (additional weights). ( ) is my guess and may be wrong. Removing 10g slightly modified those characteristics.

My friend's RC10 as shown in page 5. He replaced the world's re-re chassis to C stamp.

Weight distribution is similar to my RC10 Ver. 3 in page 4. But he uses the original rear hub carrier, Kyosho big bore shocks, and CVA AS9911. The rear shock tower is same height as the original (Ver.3 uses the shorter one). He uses the forward transverse battery position for jumps.

[R16]

<RC10Mid Ver.2>

I changed additional weight positions for the track in above videos (because of jumps).

[R16]

<RC10Mid Ver.2>

The car turns better with this camber link position (the second hole from the out side on the B4 rear hub carrier)

[R16]

<RC10 Laydown Ver.4>

I modified RC10 laydown ver.2 in page 5. Rear shocks are placed in front of rear arms. I will report how to make it.

[R16]

<RC10 Laydown Ver.4>

To move the rear shocks forward, you need to make a shock tower mount.
I used the RC10GT transmission brace (ASC7670) and RC10B44 shock tower mount (ASC9714) and those are combined.

My friend made it for me and used aluminum to strengthen it.
I made an additional transmission brace which connect the forward transmission holes.

Spacers are required to keep the additional brace flat and the lowest holes on the shock tower (ASC9904) require countersinks.

[Chewbacca]

I have to say what an outstanding build!

I might try something similar with my mid motor conversion. Currently I have the shocks and tower all the way in the back, which places the wing even further back.

Very inspirational!

[R16]

Thank you Chewbacca.

・For the battery holder, button screw is used on ESC side and cap screw on other side
・The battery cup is fixed with one screw (cap screw side) and double-sided tape

・Motor cooler is also used to hold the battery
・10g below the battery in front of the motor

<Rear>

・AE stock rear arm
・ASC9911 CVA shaft, ASC7367 RC10GT 1.5 degree rear hub carrier (toe-in 1.5+3 = 4.5 degree total), and RC10 stock rear wheel

<Impression>
・ The car is twitchy because of the short wheelbase. I noticed that the wheelbase of RC10NDS buggy is same as long wheel base RC10
・ I use ASC9911 CVA shaft which is very hard to find and am worried about replacement

<RC10 LWB (long wheel base with 13 mm big bore shocks) >

This car is based on RC10 SWB stock in page 6.
I remove the rear brace and use the long wheelbase position in rear arm mounts,

Front 1.7mm piston 450CS oil (Kyosho) white 13mm spring (shock tower center, arm outside)
Rear 1.8mm piston 350CS oil (Kyosho) gray 13mm spring (shock tower second from outside, arm outside)

I use smaller X-rings (Japanese company TRION).

I use M3x25mm set screws and the blue spacer in the pic is 3mm thick.

<B3 with big bore shocks>

This car is same as RC10B3 in page 6.

<Front>
12X23mm V1 big bore shocks (buggy front)
1.6mm piston 400CS oil (Kyosho) blue 12mm V1 spring
Shock tower center hole, arm inside

The blue spacer on the top is 3mm thick. ASC6473 shock bushing is used.

<Rear>
12X36mm V1 big bore shocks (truck rear)
1.7mm piston 300CS oil (Kyosho) blue 12mm V1 spring
