The short reversible arms are a hard plastic exact copy of my arms. The B mount is for a TRF415 and fits good with a TB01 chassis (not an XB mount) but IIRC it will increase toe-in by a full degree. But then again, if that's what you're aiming for, go for it.

Actually I think the XB suspension bridge mount would do what I said; and the B mount will increase toe-out. I'll get back to you on that but I think someone on this thread already found out the (Tamiya?) bridge mount numbers.

Sorry - the B mount is smaller and the XB mount is wider.

Why are you using foams on asphalt!?!?!? Don't tell me everyone is using foam on asphalt . . . . Only 1/8 scale 2WD F1 cars use that only b/c their tires are super wide.

Carpet yes but too light on pavement and no traction just drifting . . . D compound tires and up at my asphalt track, foams for the inside carpet track with that yay tire sticky spray during winter indoors . . .

I've been running the car with the upgraded servo saver. After changing a new servo I've noticed that there is a lot of free play. Is this normal or there is a problem with the servo saver ? I've looked into the assembly but all seems ok.

Any feedback appreciated.

Tks.
All you need to do to fit the side brace with a brushless motor is use a 3mm shim between the chassis and the side brace, that's what I did and I haven't had any issues so far.

The Tamiya servo savers do wear out pretty quickly and develop excessive play, so either replace the servo saver or look into a different brand servo saver.

Yea just add the 3mm shims, and use longer screws if you need to. I havent had any problems with this setup either.

I use foam on asphalt, it is a low traction track and foam works much better than rubber. Some guys use tire additives on rubber tires and that seems to work for them.

Kimbrough servo savers are good imo if that helps. had the small one for about 3 seasons of racing and only now has it got too much play in it.

They do a larger one too, both come with a selection of inner parts for different brands of servo.

Has anyone had any experience with the Tamiya spool for the TA05? I am just a bit worried those plastic drive cups might not be up to task in a more powerful application, say 10.5 BL?

I've been running the Tamiya TA-05 spool for a while but the drive cups are steel, are you using the Tamiya spool or another brand. The TRF415/TRF416 spools used delrin cups on the spool, on there own they are crap and break for nothing but used with the reinforcing aluminum tube which slides over the delrin cup they get the job done even with low turn mods.

I was just asking about the Tamiya 53877, don't have one. I thought formt he pictures they looked like plastic which as I said seemed a bit iffy. So they are steel? OK then.

The TA05 spool has steel outdrives. I just received mine today in the main and they are steel.

Hobby shop has a ton of foam tire but no rubber......Me being a person who tries to support the local hobby shop...Well.. I buy the foams.......But from what I have seen I think the rubbers are faster.....Could you tell me what is a good fast rubber tire with long traction life.......My track is between 90-130 degrees hot.

I understand you're running on pavement.

A good tire to try is the Muchmore absolute traction range in whatever temperature you find fit (perhaps start with 28 or 32 and medium insert - Aqua or blue). Sorex tires are another option but have a shorter life, or you could try tamiya tires compound A. Again, medium inserts.

Just brought two set of foam tires yesterday.......One set of kyosho....And one set of BSR.... When those are done I think I will try the muchmore brand rubbers....seems like I saw them at tower hobby.
