Contrary to what many people think, a lot of stuff in the States are made elsewhere like Taiwan, Indonesia, Malaysia, Korea etc.

By the way if anyone wishes to recomend a really good servo please do so!

Also calimassive..what servos are you running and what do you mean by unresponsive?

I suppose one of the factors that effects me is that I primarily run rubber tyres on a med/low-traction track so torque is not a great factor however the-rr is going to be run on a high-traction track with foams so it could be interesting!

I am sorry but there is NO WAY that a 3003 is adequate for serious open class gas racing. They will point the wheels and open the throttle but you lose a lot of corner speed due to wheel wobble and you braking power is seriously down. Notice I said "serious" racing.

I have put some Futaba 9450 servos into my V1RR for both servos and the car was instantly a different beast. It has incredible steering and super powerful braking. You really do notice the difference.

Also the digital servos make the feel of the car more sensitive. Analog servos are less "granular" then digital servos so the ditial servos respond more accuratley to small control movements.

The best part of the futaba is the unbreakable geartrain, very tough case and the motors are awesome quality. If you have ever opened a JR or Hitec servo motor you will see the brushes and commutators are very poor quality. The JR in fact uses 3 small brass colored "tabs" as comms, hardly long lasting.

Get a Futaba 9450 you will not be sorry.

Also you are correct about the rubber/foam thing. Once you run on an asphalt track with a 1.5hp motor and foam tires those 3003 will get a big workout.

You you got that right. I don't care really where things are made, you can tell quality items by asking around on sites like these.

Well.... "made" is different than "designed", Futaba, JR, Sanwa/Airtronics, KO propo, are all Japanese companies, and their products are "designed" in Japan, but im sure some are "made" in taiwan or malaysia or wherever, because of labor costs.

Moreover, who in the US, or anyone else for that matter, dosent know that alot of things are not made in the US???? you must be talking about some pretty stupid people. I think what Squizzy was talking about was, that in Aussi land they might get some of the Taiwanese or Malaysian manufactured parts as opposed to the higher quality original Japanese manufactured parts, as we do in the US. Who knows if that is true, but the point is, Japanese manufactured stuff is higher quality for the most part, than Taiwanese or Malaysian. I think some of you missed that point.

BTW, bad news. I just got an email back from RCimports, the importers for Kawahara in the US, saying they cant import the Zac tuned OS engines to the US right now and that they are in the process of trying to do so. I think it might be in conflict with the current importer of OS engines, who also doesnt import the Zac tuned engines.

Oh, Squizzy, what i meant by "unresponsive" was that, with the stock servos (94102Z) the steering response time seemed a bit slow. But what do I know???

Yep, what you have stated above is the reason for my earlier reply. I get the impression that Squizzy thought in Aussie land, they get sub standard parts as opposed to the States... Which is not correct as you know it...

I am a good driver and I have a new MT-12. SHould I go with 17/20 and leave the stock 48-44?

You need to true you front tyres to suit you overdrive. The big advantage is you can run a small tyre on the front of the car, so the steering will be a lot more direct.

Therotically, if you want the fastest straight line speed, get the largest pinion that you can find for the car together with the smallest spur you can find. This is for the 2nd gear...

Vice versa if you want a high puching car...

All this sounds interesting but in order to match the highest engine torque when you hit 2nd gear, you need to play around with the clutch. Some combos work with some engines, some don't.

Yes, you are correct. Lower ride height too.

Also, the reason why people use overdive is to compensate the different front and rear wheel wear rates.

Go for it man.... but before you do, you should look at where you are racing.... if your racing. how long is the straight... is it tight in field.... having a high top end is useless if you dont have the room to rev it out

The newer Futaba S9451 digital high speed/high torque servo's look very nice too. I think just like the S9450's they are made specifically for car use. The S9451's are described on the Towerhobbies site as being especially suited for Touring Cars. The release date is late November and there about 20 bux cheaper than the S9450's. The S9451's also have the same speed 0.10 as the older S9450's but have a higher torque rating at 6 volts: S9450 = 111 S9451 = 120. That's what it says on the Tower site anyways. Sounds like you're getting a comparable servo for slightly less, if you wait about a month.
