What is your budget? I would look at the Novak Havoc/XRb 8.5 or Sidewinder 4600 or 5700. The Sidewinder will be faster.

i own a rustler also...and also want to do the conversion ...

but after looking into it, ill be spending close to 3 times the amount that my trucks actually worth (no offense to rustler owners)

so instead, im turning my head and looking towards a LOSI or a AE to purchase..granite they wont be brushless( at first), but your rustler will help your driving skills in the mean time, til you get a faster vehilce.. plus a LOSI or AE has alot better performance and set up rating, then the rustler...

but the down side is...after buying a new stadium truck and a brushless system youll have some money into it (but its worth it to all of us )

p.s- im also a 100% sure if you wanted to convert to brushless and keep your rustler, it can be done cheap if you wait it out and search for used parts...

Two converted Rustlers in the house here, both with Mamba Max 5700 set ups. I would go with the Mamba Max as first choice or a Sidewinder as second choice. If you are converting a stock XL-5 you will also need 5x11 bearing carriers and bearings, steel idler gear, and a steel ring diff housing

when u order a bl sytem be sure and get a good supply of spur gears, the stock spur in a rusty or stampede can't handel the tourq. my friend went thru 4 spurs in one week with stampede and 5700 mm. and +1 on the losi/ae-started with a rusty and now it's losi all the way

Have to disagree with that. If you are stripping spur gears there is something wrong with your gear mesh or your motor is shifting messing up the mesh. I have worn out not stripped my last two spur gears. The teeth just get worn to where they rattle and make more noise than I like but they are still running.

THIS IS NOT MY ARTICLE. BIG THANKS TO THE AUTHOR - I'VE HAD IT IN MY BOOKMARKS FOR A WHILE!

R/C Truck Gearbox Maintenance
By brianp

R/C Truck Gearbox Maintenance How toAre your gears grinding? Have you noticed a recent decrease in performance? Or has it gotten so bad that the truck doesnít even move anymore? Weíve all been there. Usually we get so caught up with flinging our rides over the biggest gnarliest jumps we can find that we neglect to think of all the abuse weíre throw at the transmission. These things arenít usually sealed so if youíre running through sand, water, or mud youíve likely got a gearbox full of crud and needs serious attention. In our case however we noticed a slight clicking sound on a new Traxxas Stampede when jumping large obstacles. If youíre in a similar boat or havenít touched the gearbox in the last millennia then this article is for you.

The following is a quick how to article on the proper way to remove, clean, and reassemble your radio controlled truckís gearbox. The truck pictured is a Traxxas Stampede XL-5 but since every model will be different this article doesnít get into depth on the exact locations of screws and such that need to be removed. Instead this is meant to give you a general idea of the steps involved.

Pictured below is the motor and transmission on our Stampede. It is setup like most ďstadiumĒ style trucks with the motor sitting as far back as possible. Usually with this sort of setup the motor turns a pinion gear which drives a spur gear. Coupling the spur gear to the transmission is a slipper clutch. The slipper clutch is meant as a means to dampen the torque of the motor from the transmission gears under hard acceleration and heavy landings. Weíre getting ahead of ourselves though because before we can get to all of that we first need to remove the truckís rear tires, pinion/spur gear cover, and then the motor itself. R/C Truck Tranny Maintenance How to

Pictured below is what youíll see when you remove the rear wheels. The arrow (A) points toward the drive pin. Be very careful that you donít let it fall out onto your living room carpet otherwise youíll be searching forever. Donít ask me how I know.R/C Truck Gearbox Maintenance How to

In the image below you can see the pinion/spur gear cover after itís removed. Immediately after removing the cover we found the culprit (B) to our woes. A small pebble was stuck inside there and when we would hit a hard landing it would vibrate around and hit the gears. Luckily it didnít damage the teeth on either
Radio Controlled Truck Gearbox How to

Here is what the smaller pinion, and larger spur gears look like with the cover removed. Your next step will be to remove the motor but first youíll need to remove the pinion gear which is held in place with a tiny allen head screw. The large black thing on the spur gear is the slipper clutch unit we spoke about above.Radio Controlled Truck Gearbox How to

Hereís a picture of the gearbox from the other side with the motor removed. Check out all the garbage that was stuck under the motor.Radio Controlled Truck Gearbox

Here is the gearbox removed. Again we wonít go into much detail as to how to remove it from the truck because that will vary greatly from truck to truck. However we can tell you that itís quite easy and usually consists of removing a few screws from underneath the chassis which hold the gearbox in place. Then youíll need to remove the drive axles, and a few other small bits to get it out.Radio Controlled Truck Transmission

Pictured below is the transmission removed and disassembled. Because our truck was so new the inside of our gearbox was impeccable. However youíll likely need to remove each gear and clean and inspect it for wear or damage. Missing or rounded over teeth are the usual problems. If you find either then itís time to replace the part in question. We were pleasantly surprised to find that the Traxxas already had bearings installed. However if your truck is equipped with plastic bushings this is the perfect time to goto the local hobby shop for some bearings. As for inspecting bearings try rolling them in your fingers. If they feel gritty itís time for a replacement. Most hobby shops stock individual bears so you wonít have to buy an entire set. After cleaning all the gears and inside of the box itís time to lightly lubricate each gear and bearings and reassemble. Remember that excess grease on the gears will cause a decrease in efficiency which will result in decreased battery life and a slower vehicle. BTW our vehicle came equipped with a gear differential. If however yours has a ball diff this is the time to disassemble it and replace parts as needed.Radio Controlled Truck Tranny Overhaul

After everything is back in the truck the final thing youíll need to do is to set the mesh between the pinion and spur gears. Some people can do this by eye, but if youíre new to this sort of thing I suggest trying the old paper trick. It consists of taking a small strip of ordinary paper and sliding it between the gears. Then push the gears together and tighten up the motor screws to hold it in place. When you remove the paper your gear mesh should be set just right. Want to make sure? Hold the pinion gear still (usually the motor will do this for you) and lightly rock the spur gear back and forth. You should just be able to see a little wiggle room between the gears. If there is absolutely no wiggle room then itís set too tight. If there is so much wiggle room that it looks like the gears could slip then itís too loose.
How to set your pinion gear mesh

Overall removing and maintaining your gearbox is really easy and can save you money in the long run.

The mamba 6900 is great for speed and power.

I currently run it with a EP 4200 6 cell and get 40
