anyone experiencing a loud shudder when 1/2 to full throttle and turning the wheels in either direction? say about 1/3 turn and higher?

i'm thinking it's the one way front "diff"?????

this is when the car is up on a rack and i'm listening and looking at it closely.

And has been said before... ignore it!

It's do to with the fact that the CVD's are not true constant volecity joints, and there is always a little binding in their action. Doing it without any load and a spool will only make it more apparent. It will happen with every car on the market that uses the CVD-style driveshafts.

It really isn't something to worry about, and given the only set of dual-CVD's that seemed to be reliable were on my old Losi, I've never bothered looking at other solutions.... to put it another way (maybe a little tenuous), but the 416 won two IFMAR worlds with those CVD's up front...

I had the same issue last weekend when i was assembling mine. Make sure you are using the right bushings, there are 2 types that are VERY close in size, the other thing double check for burrs (there weren't any on mine) on the teeny tiny ones. Once i had the correct bushings in place things were super smooth even when tightened down.

The other thing i found was that I couldn't fit the correct number of shims (1x3mm) infront of the rear arms ... i tried just about every permutation and i couldn't do it. can somoen take a pic of their spacers in front of the rear arms for me?

now, about the steering. looking at the manual, step 8 page 7.

1. shims are silver and spacers are blue anodized, right?

2. right now, without a servo and just moving the steering by hand, the 2 screws BA1 that goes into steering bridge BB20 will loosen up after a few cranks. if i tighten them down, it binds. it seems that there needs to be a shim on the top, not just a the bottom of BB20... right?


thanks... now for sleep... lol...


one more thing... no other way to mount the battery besides using tape (either double sided or actual batt tape)???

Does anyone know if the 417 diff rings will fit on the tamiya aluminum diff joints for the ff03?

The 417 has 2 flat spots on the rings, but I cant tell if the ff03 alum diff has 2 notches or not (from pics) and if the diameter fits. I have neither of the parts to compare.

Thanks

Default Tweaked car?

Just finished assembling the 417 and noticed that, when the shock preloads are the same, there is unequal ride height left to right by approx 0.5mm, which is giving me a tweaked car.

The only way to rectify is by preloading the battery side shocks much more than the ones on the other side. Now the ride height is equal and there's no more tweak.

What could be causing this? Also what would be the drawbacks of running the car the way it is right now as explained above?

Anyone experience this?
thx

Tory, best thing to do is get however many shims you want on the setup sheet side, and then fill the other side up with small shims until the play is right.

what i eventually did on mine was i noticed that i needed to add enough shims to the cross bar is flushed with the steering arms.

now, it's solid tight and it turns easily...

Simple answer, no drawbacks, IMO.

Double check your shock lengths, and make sure all the holes are right on the arms (trust me, done that one..). Also check the suspension blocks/hinge pins to make sure there are no bends.

If it's still out, it's most likely either a little bit of weight balance out, or a little bit of tweak in the chassis plate. You might be able to solve it with a bit of a re-jig on the electrics, or utilise the "push down on shock towers when tightening top deck" technique. However, personally, anything up to a full turn difference on the spring collars is fine, as this means that each tyre is getting equal loading... I put that above equal ride-height in the scheme of setup.

My 417 tends to run between 1/4 and 1/2 turns different on the rear (front is norma equal), and never have a problem with tweak. Bear in mind this is done with an MIP tweak board, so it's pretty close to being spot on.
