Traxxas created another hit when they introduced the 4 x 4 SLASH. Durable, fast and most of all, fun to drive. Traxxas is the company that started the short course truck craze, just like they did with monster trucks several years earlier.

It didn’t take long for the other names in RC to come out with their version’s of short course 2wd and 4wd vehicles of their own. Manufactures like Losi and Associated who tend to make competition level vehicles, were quick on Traxxas’ heels and released better handling versions that the more racer oriented folks typically purchase.


Enter the Traxxas low CG conversion. The already good 4 x 4 SLASH could now be made to handle even better by converting the chassis and a few other components, which lowers the overall center of gravity significantly. The lower the CG, the less potential for body roll, the better handling the vehicle will be, which should make the vehicle faster through the turns.


Since the shop has an older SLASH 4 x 4 demo vehicle for customers to drive we thought it would be neat to see just how much better the new chassis design is. The idea being that we would bring the stock SLASH to our local indoor track, (Smac Trac), to get some average lap times from a couple different drivers. Then convert over to the new low CG chassis, and have those same two people get average lap times for comparison, hopefully proving that lower CG will improve lap times.


Traxxas part #7421 includes everything needed for the conversion. Chassis, new style battery strap (no more body pin), motor mount, and front and rear suspension arm mounts. It also includes a little instruction sheet exploded view showing how it all goes together. The conversion itself took about 3 hours to complete.


After tracking average lap times for Dennis Fischer and myself, our two average lap times came out to 25.29 on the original version. The low CG conversion dropped our average time to 23.67. That is over 1.5 seconds faster!


The addition of sway bars, GTR shocks, and a center diff should make it faster still. This is a perfect example of creating speed, not by increasing horsepower, but by making a better handling vehicle.


Conclusion: We thought that lowering the CG would make for a better handling car, which in turn would make for faster lap times, it did!

A Comparison of the Heli-Max 1SQ and Traxxas QR-1


The Heli-Max 1SQ and the Traxxas QR-1 are the latest in quad rotor helicopters. Because of the quad rotor design, they are considered fairly easy for the beginner to fly. Both are palm sized, the 1SQ being slightly larger and are both ready to fly, including extra rotor blades, a USB port type charger and battery. The QR-1 includes an extra battery, as well.

The Traxxas QR-1 is the easier of the two to fly, out of the box. Controls are toned down by comparison to the 1SQ initially, which gives the beginner a little more time to react and adjust. After experience is gained, the controller can be changed to expert flight mode, which is much faster and more responsive. This allows flying back and front flip’s and barrel rolls. The LED lights do add cool factor, and it is nice that there are many body and blade color choices allowing for customization.

The Heli-Max 1SQ has the hotter setup out of the box. Where Traxxas has two flight modes, normal and expert, Heli-Max has adjustable rates from 30 (mild) to 40 (hot). Set at 38 from the factory, this allows stepping up how aggressive it will fly in smaller steps, as opposed to one big step. Also, the 1SQ is AnyLink compatible, which means it can be used with after market radio manufacturer’s transmitter’s, such as, Futaba, Spektrum, JR and Hitec. Since the 1SQ is AnyLink adaptable it is available in a TX-R version that is less expensive since you will be providing your own transmitter.


Both helicopter’s include a set of instructions going over operation, as well as explaining how to adjust flight modes or rates. Because we guarantee all RC items to break, both include exploded view diagrams and corresponding part numbers that allow for fast and accurate parts replacement. Fixing either quad is a simple task requiring a Philips screw driver, included with both kits. The one exception would be that on the Traxxas QR-1, motor replacement’s will require soldering skills, that may better left to the hobby shop’s to replace.

Mark Twain Hobby AT NHRA Midwest Races

Last weekend at the NHRA Midwest Nationals at Gateway Motorsports Park in Madison Illinois (just across the river from Saint Louis) Traxxas set up a booth showing their RC trucks and cars.  Mark Twain Hobby Center was represented in the booth by Sean Cason, Dennis Fischer, Darren Vancour, Bob Fowler, Sherrie Stueck and Jerry Dean. Way to go guys (and Sherrie). For more pictures check out this link at KPLR TV:

Traxxas Robbie Gordon Speed 1/10 SLASH

The Traxxas Robbie Gordon Speed 1/10 SLASH 2WD RC race truck had only been available through Robbie Gordon and they were really not for sale but promotion. Due to a shipping error from Traxxas to one of our suppliers we were able to get hold of some and have them available ready to drive. Here is a link to them on the website:

This is one cool truck. Take a look at the other graphics:

They will go fast so don’t delay.

Have a great day.
