anyone used foam on your 416? im having problem in getting the rear and front wheels to wear out the way i want it.
Rear and front wheels are always coneing out.
My camber is already 3deg and increasing it wont be any good.
Anyone have any idea why does it cone this way?

I have a setup from Corey running foams, but I think thats for carpet. Corey Foam setup

Could be related to camber change, so try setting the car up with flatter & longer links, as this will reduce the amount of camber change as the suspension compresses.

Hi,

anyone has tried to fit the MS/MSX Steering to the 416? On the race in Thailand we will see at least one car equipped with the new (better say old) steering which seems to work much better on asphalt.

I have to say, the steering on the 416 isn't the same as that on the 415MRE... namely as the steering is slightly further forward, but the bell cranks are shorter. This is partly the reason for the bigger number of spacers used.
The steering feel seems to be better with the 416, and given it is also adjustable in terms of ackerman position, I don't see any reason to change back.... (Then again, I also never had issues with the MRE system... and the reduced slop was a welcome change! )

Not too say it wouldn't work, but there's other parts of the setup I'd change first

Regards
Ed

going to try a whole new setup tmr. just installed my short arms. im using 44mm rear shaft and it seems to be very tight and the front im using 46mm with a one way and it also seems very tight.

Rear block using X1B/D and front blocks D/D
wonder if it will cause any problems on the shaft.

i was also using 30mm width rear foam wheel and now changed to 26mm width as the wheels were touching the shock at the bottom.

doubt it will run good as rear tires are narrower now.

46mm on the front will be fine, just remove the O-Ring from the outdrives if your running a one-way. The 3mm thick o-rings are slightly too thick, try and find something ~2 - 2.5mm thick if your worried about the outdrive cups moving. I've found the Much More O-rings are good at this, as they are slightly thinner than the tamiya ones.

As for the rear arms, you might need to remove a little material from the plastic driveshaft blade on the right hand side, as it can touch the top of the diff nut otherwise. Just run the edge of the blade over some sand paper, removing about 0.5mm of material, then you should be good to go.

I would normally say that I'll take some pictures for you this evening, but given that it the 14th, and I've got my missus coming over tonight... so no chance Maybe tomorrow

Just want to let everyone know that I put in the 115T 64P with no problems. Actually I think the chassis can take a larger spur but I think 115 is good enough for now.

Also I changed to a 24T pinion and I am able to adjust the mesh a lot easier.

Thanks everyone for your suggestions!

Use XA(X)/1E for the rear. you can use the stock swing shaft and keep the width same.

Well the new car is on order. Any advice for building. Little tricks or hints. This is my second on-road build but I've built a ton of off-road cars. I would really appreciate all the help.

Has anyone been running a 17.5 BL on this car? What size spur and pinions have you been using to get close to a 3.5 FDR? Also, anyone know what is the biggest pinion that can be run with the 105 spur?

hmmmm, I think a 44 or 45 pinion can be run with the 105 spur. I currently run a 102/46 combo with my 13.5 and it's close. A 47 might rub the top deck with a 102. I would switch to a 96 or smaller spur if you are gonna run 17.5. 105 spur is only good for brushed motors and mod brushless.

bboy, you didn't have to mod out the chassis to get the 115 spur to fit?? My 108 seemed to be my limit on mine. I'll have to recheck later on. I could of swore a 108 would "almost" rub the chassis opening.

Thanks for the info JMac!! I'm gonna switch to brushless soon...I got the speedo just waiting on some motors.

Yeah, I'm waiting on the SpeedPassion 17.5 to come out. Then I'll try 17.5. That or wait for Tag to label up some 17.5 motors. You running at Mimi's or Debbies? I need to head back up that way sometime again. I don't get to run rubber tire carpet much. I think this was the first year I've actually race it in a class. I have a lot to learn about rubber/carpet. I mostly do asphalt.

Actually, you might wanna try something like an 88 spur or smaller for 17.5. An 88/52 will give you 3.479 final. In order to get a 52 pinion to fit, it has to be closer to the rear of the motor mount. Not the front. I wish I remembered what the largest pinion you can fit with the motor all the way forward. I know it's smaller than a 45 pinion.
