I have yet to break a front A-Arm on the standard 415 (with no extra protection) and I hit the boards as hard and as often as anyone. I have hit hard enough to bend several hinge pin mounts but I have never broken an arm.

If that's the case I would probably stick with the Stratus 1, 2, or new 3.0 style bodies.

Has anyone tried to mount an additional rigid plastic type bumper under the foam bumper of their 415s?

With Pro4s we were putting BRP wide bumpers so that the rigid bumper extends to cover the front arms. The 415 foam and bumper mount seem ok but racing indoors it's nicer to have something wider.

Speaking of which... I broke my first part last night, or well, it was broken for me, without my prior consent....

Right front arm cracked, outer hinge pin very bent, about 10 deg caster on that side, didn't handle very well. Stayed together though, but now finding parts..... This was on the MS though.

Thanks for the info on your fan setup Ed. I'm a little worried about the fans I have burning up on 7-8v direct from the battery. One blew up while testing it on a discharged pack... I guess I'll just look for a higher quality fan, and the run a switch to the battery wires so I can control the fan.

Will this part fit the stock 415?

If so...what's the difference between that and this...

Is the lower link the rear hubs that have toe built in and the first link the rear hub with 0deg rear toe?

No prob, I'm not sure on the fans i haver, but they have a 5v rating on them... I doubt the extra 2v is gonna harm them (nothing happend yet, and i've been playing with them for most of the afternoon). I don't know if i mentioned it, but these are rated at 0.08a @ 5v, which i think is pretty low, given what our motors pull at....

Later

I believe they are the same thing, except one is made of extra hard, no flex material. I know they will not work with the light weight suspension on the MS, but I'm not sure about the standard 415 arms. I think they would fit, the TA04 uses the same arms I think.

The first one is the optional 1deg rear hubs, I currently have them on my std suspension, so yes they will fit

The only difference between the two is the Toe-in rear uprights (your 2nd link, and std fitment on the std 415) are 2deg toe in hubs, which whilst running stock, I'm finding to be a little excessive...

Basically, the 1 deg ones give you more scope for tuning lower amounts of toe on the rear. The lowest you can really go on the stock hubs is 2deg, without sweeping the arms back.

this is correct... the one set is the hard pair, which came on the 414/415 Standard series, the other set is the regular soft plastic set, which is a Hop-Up option on the TA04 series cars... either will work, but as the typical Tamiya rear hub, you will probably have to file/sand them to fit.... they will both be 2 degree...

I'm pretty sure the hard set is 1deg, and the toe in set 2deg.

I back this up, as I've had the first set on my TRF 414, and there were only 1 hubs at this time (and they are made of graphite reinforced plastic). The second one is the one given with the TRF 415 (look at the back you your instruction manual) and this is 2.

why was never a question. the diff is exposed as opposed to enclosed like the eveo4.

IMO, the gritty feeling is from thrust. I believe that the thrust units' balls are too small to work with the debris that get caught up in the diff half.

I usually run low-turn motors; if it was the rings - it would show there. Usually, a good cleaning of the thrust assembly will bring some life back to the diff.

"Investing" in a decent set of diff balls goes a long way...both the tamiya tungsten carbide and the xenon ceramic perform and last. I can get maybe 10 good runs out of the stock tamiya (LW) diff balls.
