Then just use the 37t pulleys on the car as well, you'll need to run the belts a little looser then with the 36's, but that it.

if you want to use 416's front upright, u must also change the bearings and C-Hub to 416 version. CMIIW.

but i don't know the swing shaft, whether it still can use the 46mm swing shaft or must change to 44mm (416 version).
Actually, the 415 C-hub will fit with the 416 steering block... I ran that combo on my 416 when I first had it after ripping through the (rather fragile) carbon c-hubs....

Otherwise, yup, your correct, the bearings need changing to 1050's, as do the axles (different bearing spacing).

getting a little disgruntled with it !!!
Really??? I've never found the arms to be brittle at all... I think I've only broken 3 or 4 in 5years or so of racing tamiyas! I can't recall the last time I broken an arm on my 416 (uses the same suspension).

Other parts in teh steering I've broken, but otherwise the suspension is pretty damm robust.. and I've had some big hits (flat out into the barrier at WLRC being one).

Is it hard corners on your track? I know this sounds silly (and far be it from me to tell people how to drive), but maybe try dialing in some more understeer into the car to help it push wide of the apexs... at least till you get used to driving a TC.

my problem on our track is the fast left after the back straight i just cant get it right and i either run wide with too much speed and hit the outer barrier breaking the right lower arm !!

or i turn in early hitting the inner barrier breaking the left front arm !!

i have broken 7 in the last 3 to 4 weeks GRRRR

maybe the 10.5 turn brushless and TC spec speedo is just too quick for me

Hi guys

What difference does it make if you change the pulleys to lower the internal gear ratio? I'm using my TRF in stock racing and any advantage I can get out of this will be great!

What pulleys and belts will I need to get the lowest IR then? Thanks

Thanks Ed, I just wasn't sure if the belts you had listed would be long enough with the extra tooth on the pulleys.

Ricky go to this link it has the part numbers for the belts

http://www.thard.co.uk/415/tips/18tpulleys.html

Ricky firstly it drops the internal ratio to 2.055 which lets you get to the bigger rollouts for silver cans without having to use the biggest fly wheel sized pinion you can find and so the motor has less rotational mass that has to be spooled up.

Maybe TryHard can tell us if there's an advantage to running a lower IR, so if you have 2 identical cars but one has a IR of 2.250 and the other has an IR of 2.055 and both geared to rollout at at 42mm. Would the car with the lower IR have an advantage of any kind?

I think the SMC 4000 may fit under the low bulk heads. I'm running the Orion 3800 but I had to mill the bulk head slightly to get it to fit. There are lipo tray's that push the battery out a bit so running bigger batteries should be fine. Dujuan bought the tray from Stomers and he seems to like the fit. Once I see how it looks in person I may go and get it. No mod for me. I'm sticking with 13.5 for now. That's what I'm running for the Reedy this time around.
