sdmlsu1 asked for pros and cons of shaft and belt drive and I gave it to him. Yes, I prefer belt drive over shaft drive after having driven both types of cars, because shaft drive cars suffer from torque steer.

Funny. I have a shaft drive car and run 7-turn motors all day long. I seem to have NO torque steer in my car.

Yes, your car can HAVE torque steer if it is not set up correctly...and, if I'm guessing right, mtx-2 is NOT going to be running hot modified motors...so, even IF your car exhibits torque steer and you THINK it's because of a hot modified motor, mtx-2 will most likely be running stock or maybe 19t.

mtx-2: you can't go wrong with either car. I, of course, vote for the FT TC4, but I'm somewhat biased.

I had both a Team TC4 and the Losi JRXs. I gave the TC4 to my 6 year old son to bash with. I sold the Losi. Here are the reasons. With the Team TC4, I could not get it to turn in no matter what adjustments I made. Compared to other racers on asphalt, my TC4 just could not stay up with the other brands of cars in the turns.

With the Losi, I was very frustrated by problems with chassis tweak that was hard to banish. Also, the build quality was not good. The counter sunk screw holes in the chassis were not deep enough, so almost all of the screws were not flush with the chassis, but stuck down by varying amounts. Another problem (which is now solved) was that to get optimal handling, the Losi needed custom fabricated shock mounting brackets. Losi has finally released revised suspension arms that incorporate this new shock mounting, but I got really tired of waiting months for these parts. Finally, the Losi center battery design while cool is really a pain. It requires very carefully built battery packs, with very precisely located battery bars and you need an accessory battery tray for the new high capacity cells. Wiring the batteries is also a pain since you cannot easily use Deans plugs. You either have to solder the batteries or use Corally style bullet connectors. All in all, the Losi was just more trouble than it was worth.

I ended up getting an HPI Pro4 Hara Edition. It was much more dialed right out of the box than either the TC4 or the JRXs. Also, the drive train is much better shielded than on either of the other cars. Thus, I get far less dirt, pebbles, etc. sneaking into the Pro4 and messing up gears. Finally, in my experience as well as that of several magazine reviewers, the Pro4 has no torque steer despite being shaft drive. I have run mine with an 8x1 mod motor that had no trouble running away from a 1/12 car with a 9x1 motor and it ran straight as an arroweven under the hardest acceleration.

The only down side with the Pro4 is that as delivered it is optimized for asphalt. For optimal carpet performance, you would need to purchase new thicker top and bottom chassis plates. I have not done this and mine Pro4 runs well on carpet, but likely could be faster with these mods.

In my area, the most popular cars are the Xrays (mostly T1s, though I don't think there is enough data to know if the T2 is really the next big thing) and Corally RDXs. Also in my area, parts are most widely available for (in order) TC4, Pro4, Xray T1 and then fairly spotty coverage for the rest. Don't overlook the importance of parts. It is no fun to end your race day at 10 AM because you broke a part for which you have no spare and there is no local parts support.

Another possibility for budget minded folks is the new Tamiya TA-05. I have read very positive reviews and one of the locals recently ran very well on asphalt in 19T with a freshly built TA-05. If you shop carefully, you can get one for about $150 (or $90 if you have a friend in Japan ;-). Note, this is likely mostly an asphalt car.

Good luck,
Ira

Actually you gave him neither pro's or con's.

I've currently run both as seen in my signature. I ran my FT TC3 for 4 years in stock and 19 Turn and it never once showed signes of torque steering. I have run down as low as 10 Turn in my TC4 and I had no evidence of torque steer. As Tphalen stated, if your shaft car has torque steering, your car is either tweaked or set up incorrectly.

sdmlsu1:

Bottom line is this:

Shaft has more punch or the feel of being punchier...all other things being equal, shaft is faster off the line and out of a corner due to the throttle response. Also, IMO shaft drives seem to like to be driven harder or more aggressive. Nop matter how hard I drive my TC4 it just screams to be driven harder.

Belt: while not having the great throttle response that shaft has, they are smoother and more forgiving. For me, I am more consistant with a belt car.

When comparing my RDX to my TC3, I am more consistant with the RDX and it seems easier to drive. However, My fastest lap times are with my FT TC4 but since my lap times are not as consistant, my slower lap times are slower than with the RDX but in the end my average lap time is the same with both cars.

It comes down to driving style IMO.

Shaft also has much less maintenance and easier to work on. No belts to replace, stretch or have to adjust the tension of. Sealed diffs so you are not constantly rebuilding them.

I was a dihard associated guy until the TC4 came out. I have tried just about every adjustment in the book and my stock TA05 was faster out of the box. Like mentioned above, I had the same trouble of getting the car to turn. I ran on both prepared asphalt and CRC fast track II carpet. On the asphalt I ran both rubber and foam but it didn't seem to make much of a difference. I gained on the straights because of my cheater brushless power, but I basically lost that in the turns. On carpet, we pretty much run stock rubber as the main class. I have no advatage of speed now (in fact I am down to some of the guys with better batteries) and I don't make up any time in the turns.

I bought my ta05 just for fun since it was cheap, and I can't believe the performance I got for $125. Right out of the box I was beating my best lap times from my TC4. The cars that are always in the front of the pack at my track are RDX's, X-ray's (any of them), and Tamiya's (TA05, 415). I have seen a lot of TC4's and JRXS's come and go. Word on the street is that the JRXS isn't going to be around for long.

I like my FT TC4 alot although I never ran a JRX-S. I used to run foam with the tc4 and it ran pretty good with online setups, now I switched over to rubbers and it runs great also.

If you get FT Tc4, BEWARE of the dreded blue screws...strip left and right.

I have had both cars. The Losi has a coolness factor and alot different than most cars. The car has a ton of adjustments so that is good or bad depending on how much you know about setup. It isn't too hard to work on as I first thought when I got the car but really its not bad. Only thing I didn't car for was redoing all my battery packs to fit this car. It is a tight fight plus you need to modify the stock battery holder or buy the new alum one to fit the newer sized batteries. You build the packs with out shoe goo as the pack can't be too long. Soldering the pack in was not really hard but if I was in a hurry because you get your iron close to the belt. The LVD's are nice when running a spool. No chatter in the corners. Bad thing is you really need to check them as they come apart easier that some other setups of driveshafts. Still pretty cool feature.

I had the Team TC4 and later the FT TC4. The Team is nice anc cheap but I found it wasn't as consistant as the new FT TC4. The FT is really easy to work on and has a fair amount of adjustments but not so many to overwhelm you like so many other cars. Drivetrain with a little messing around is as free as they come and still have great snap out of the corners. Mine was really good on asphalt and not as good on carpet. Never did try to make it work good on carpet so thats not a fair comparison on my park. Batteries fit nicely. One thing is if you run a spool it is easier to chop teeth off the front spool gear. No slippage to it does happen. Torque steer was never a problem for me.

Of the two the belt seems a tad bit easier to drive but the shaft is to me still a tad quicker out of the corners and I think has a little more room for error on the gearing.

If I was buying a new one of these cars I would go with the TC4 but its just me. For used I would buy either one depending on the price because both can work. Just need to hit the right setup that works for you. You really can't go wrong as both companies and parts are easy to order from almost anywhere.
