might try this. The nothchyness almost went completely away on the tamiya gear diff when I added 0.3mm on all four gears.

I could not believe the difference gained an easy 0.2 per lap on a 12 second laptime

PM Besercoe on how to really free up your spool. Maybe he has some pics he can post up. It really works. Also I tried his same method on my rear diff to free that up too. In stock class the less bind of any drivetrain is key.

I think I know what you are talking about. did the same thing on my 417 a while back

I still had to add a 0.1mm shim on to the piston to remove some play.

Now for the o-rings, you guys stay with the stockers or use something else? I've a set of the Tamiya competition o-rings so I thought I'd test it out. These rings don't bulge up like the normal ones.

I use all stock rings. Use a little associated green slime and it's all good. Just changed o-rings out first time in about a year.

I was looking at various pics of the car and noticed that very few racers use the sideways two tape method to keep the batt down. Is there a reason why it's not popular?

hey Nikos, I qualified second, (thank god for qual points,) I thought I would be 3rd or 4th on the grid, the TQ had us covered all day, by a few seconds, I made a change or two for the main, and it was on, I got the shakes so bad I actually drove off the straight lol. that busted pin I found was the hold up in success at FW. BTW, I ran the 13 with the 15 shock towers and shocks.

so I put the 13 down ran a few laps, came in swapped shocks and shock towers, and could tell the diff right away, way better, a spring change, even better, and position change and camber link change, pretty darn close, then I went to work on the motor timing vs gearing. nailed it.

seriously thinking about vegas... even if just to watch

I refreshed the post on facebook under the group ARC Driver.


Thanks guys.

Saw that. They really should include a Tips and Tricks section not just setups. Got my 15 ordered. Going to have to decide which one is going to be my mod car the 13 or 15. lol

I don't think it makes a difference. Just make sure there is a little gap between the battery and the front and back holders for flex.

It probably doesn't make a ton of difference, but all the little tiny things add up to a superbly handling car.

Things i like to do when building a car:
Freeing up the spool - As per facebook
Sanding the gear diff plastics, where the bearing is seated.
Sanding the diff cams inside and out, so that the bearing fits smoothly in the carrier, and that the carrier (with bearing installed) sit in the bulkheads smoothly, this along with the top 2 points, makes a significant difference to the drive train.
Ensure that the bulkhead caps fit flush on the bulkheads (before sanding the diff cams they can rock around 0.2mm)
Ensure the bearing slide smoothly onto the driveshafts, spool outdrives and diff - if not a flat file and some time makes them perfect.
Check that the driveshaft blades are not tight, this will affect the action of the suspension, you can trim the inside of the blade, or the bulb on the end of the driveshaft.

When running a Trinity motor, i find it sits a little low in the flex bulkhead, and there is only a 0.5mm gap under the motor. I shim up the motor mount 1mm and place 1mm under the front and rear of the top deck also.

With the battery mounts, ensure the batt braces are not snug on the batter, then i use 3 layers of plain old electrical tape accross the sideways front tape slot, making a pad for the battery to sit on when taped in and i only use 1 piece of tap sideways (make sure you chamfer the tape slots, and i also put a large chamfer on the bottom of the chassis plate where the tape sits so that normal body roll does not slice the tape on the edge of the chassis.

Do all these things, and i can guarantee you that you will have a better handling car. It may not necessarily produce a faster lap time, but it will guarantee a faster race time.

I've been running the ARC 2015 since its release and long before I got my hands on one, I'd been commenting on Sean Williams' car and how smooth it always looked. Fast forward to my first run with the car and instantly I thought it was the smoothest and quietest car I've driven. After driving the car more, I really began to enjoy the smoothness. The car literally drives like a Cadillac and turns laps like an F1.

I've also noticed that the car holds a solid line on power and at high speeds, which inspires confidence as it never feels on edge. Additionally, the shocks handle bumps very well, keep the car well composed and don't leak.

There is so much more I can say about the car, but I don't want to write a novel.

I am really pleased with the R10 2015 and can't wait to see the Black Edition when it arrives at our shop this Friday.

Lol. I think you went through the entire list of things I've been telling people to do. The car is not perfect out of the box but with going through the things that you mentioned as well as some other tid-bits the car is fantastic. I really don't think there is a car that's perfect out of the box. This one is the best handling car Ive driven though. I am getting excited to compare the 13 vs 15. I have all the same electronics for the 15 so it will be all about the car testing.
