I love to pick with these guys because before they get their kits built and run in, they plop another $200 to $400 worth of "hop-ups" that may or may not be necessary. For example, I bought my MTX-3 back in early 2002. I built the car from the stock parts and spent the rest of the year learning the car, its driving characteristics, and adapting my driving styles to what the car could do. The next year, 2003, I spent my monies on my first hop-up, a better nitro motor. I wanted to run at bigger tracks and bigger events and my stock MT-12 just wasn't enough. Granted, the car was still bone stock and I had been highly competitive at the club level, winning here and there. The next year, 2004, I got better at driving the car and started to become a competitor at the state level. In our state-wide series, I finished 15th out of 88 in touring car. My only hop-ups were the lightweight two-speed housing assembly and finned motor mounts (the original mount screw holes stripped some threads). Still, the car was pretty much bone stock from 2002 and I was beating racers with the Prospec and/or lightweight, hopped-up cars on a "diet". This year, the only other hop-ups added was an aluminum pulley on the from belt shaft because I stripped the teeth off of the plastic one (after 3.5 years) and a new RD Logics chassis (because a motor mount eyelet broke causing the motor to shift under accelleration). This year, I finished 12th out of 72 in the state in touring car with an almost 4 year old stock MTX-3 (including 1.0 pitch stock gears) over many Prospecs and original kits on a "diet". I did this because I spent more time working on driving better lines (shortest distance around the track) and different set-ups for different track conditions (maximizing the car's attributes to my skills) than worrying myself gray-haired about a few grams. My car has been as low as 1728g and as high as 1825g and it performed about the same. Now, it is currently around 1785g (with OS 12tz engine) and can hang with the best of the racers I compete against (when I am on my game).

Again, I don't mean to sound like I am downing anyone that hops up their cars. I just think that it is funny that many appear to worry more about a few grams than learning the car's attributes and matching it to their own driving ability. But, to each his own I say.

This is hobby remember ? some people enjoy buying hop ups so the car look nice, some people enjoy driving only, some people don't want wasting money on hop ups, some people enjoy building cars and put it on shelf, some people have creative ideas, and so on.

So enjoy what you are doing This is fantastic hobby. I quit playing golf in 2003 and enjoy playing rc since then.

It depends whether you bet during your golf games or not. I used to golf but now my golf bags are for carrying my RC cars!

Whatever it is, I, like most people I know, can't do both.

Josh, welcome to the world of 1/10th. Good choice with the MTX-4 since the car drives well right out of the box with the standard setup. Mine is almost completely stock except for the wheel hubs (plastic to aluminum) and front drive shafts (dogbones to CVDs). My first race out I ended up finishing 15th out of 40 jumping about 7 places from my last finish of 22'nd.

Regarding braking and one-way bearings. It seems kind of stupid to have only 2-wheel braking but there is an advantage. If you pick up your buggy and turn any wheel, all the wheels will turn. This is because all wheels are joined together by gears with a central drive shaft connecting front and rear. Braking on the buggy works by grabbing the center shaft and because everything is connected all wheels brake. This is not the case with a one-way.

A one-way bearing is an ingenious design where the drive shaft inserted inside the bearing can spin freely (like in a normal bearing) when the outer housing is stopped but will grip the shaft when a forward torque is applied to the outter housing So literally, when the pulley comes to a full stop when the brake is applied, the front wheels in effect become independant of the car (i.e. they 'freewheel').

This doesn't sound like a good idea until you realise what is happening. When the wheels freewheel, there is very little friction to slow them down. In a differential, you always have the friction of gears meshing together. With little friction to slow down the front wheels, the car's momentum carries it a lot further compared to the higher friction involved with a diff. Also, a one-way is lighter than a diff and does not suffer torque unload. With a simple diff, when one wheel loses traction, rotating force is transfered to that wheel. This is great when traction is low and that's what you want. But what if a wheel hits a small bump or the cars tips lifting the wheel the diff unloads on the lifted wheel, which is not what you want. That wheel is in the air, not on the road.

The driving style of the two is different. With a diff you can brake later so you can stay on the throttle a little longer before braking to make a turn. With a one-way, you let off the throttle a little earlier and let the momentum of the car carry you into a turn. You generally need to brake earlier with a one-way.

I have never seen a head-to-head long term comparison of one-way cars compared to diff cars saying which one is faster but it has been my experince that many racers feel the one-way is the faster of the two. My advice would be to have both around. When the track is tight and grip is low, of course you can use a one-way but a diff may be easier to drive. With a medium to large track and moderate to good grip, the one-way has always worked well for me.

Thanks heaps for that information Rob. I think i will just stick with the one-way, it would probably make you a smoother driver leading to less mistakes. I really can't wait to hit the race track.

What percent of nitro due you all use, any castor oil??

Thanks ! 6061 is good enough for strength and durability.
