Oh, you want to make it so it does 100mph and really causes some damage when he crashes it...I've seen videos of those brushless sit-ups and I would even trust myself to drive one!

With the added cost of going brushless you'll also need to upgrade the charger and batteries to Lipo.

Well. They're pretty slow and boring right now. I want to upgrade mine, so I'll have to do his too

We have brushless Rustlers and they have the Nimh batteries in them and they fly. Will do 50 mph easily. There are many options to do what you want but probably the easiest is to just get the Traxxas Velineon brushless motor and ESC for the Slash. I converted my son's Rustler to brushless a few years back doing exactly that.

If you are buying the system separate, I would not recommend the Velinion setup. It's just too expensive for what it is. If you are looking for something out of a local shop, you'll pretty much have to just go see what they've got. If you are looking to order online, then hobbypartz.com isn't a bad place to order. This link will take you straight to the motor/esc/programming card combos. 13.5 and 17.5 combos are both $120.

Honestly any setup should work fine, though if it's for younger ones I wouldn't go too crazy, no lower than 13.5T. Also, pay attention to the Turn rating, a 1/10 motor may not be a full 540 size motor even though it appears to be. Whole numbers (13T or 17T) are usually a smaller armature, and can usually be told visually by deeper fins on the motor can. Half numbers (13.5T or 17.5T) are true 540 size motors, and usually have smooth cans or very shallow fins.

Either way, I would definitely recommend Lipo. Hell, you may wanna do that first, since that will actually make the stock Titan a fair bit quicker on it's own, though it will also let you burn the Titan up quicker as well.

www.amainhobbies.com is good for pricing too. NiMh on brushless will fly. I 'trained' mine on NiMh before I trusted myself to LiPo.

But I ruined a LiPo. Expensive lesson.

Do you ever go to the track in GB?

Get some extra pinion gears and spur gears to keep on hand. With the higher torque, until you learn to control it you may strip them. Better to have them on hand than to have to run into Flint to buy them, or to have to wait to order.

As for switching to Lipo first half the reason we want to convert to brushless is because of reliability of the stock system. In talking to the guys at a few hobby shops and my frsutrations with reliability (and my general troubleshooting and repair knowledge of RC shit) they suggested we convert to brushless as it is not only faster, but much more reliable than the stock traxxas crap. Your thoughts?

I love my Slash 2wd trucks. I have 3 of them. For Christmas I would consider giving them two modifications.

Castle Creations 1/10 SV3 Sidewinder SC + 3800kV w/5mm
http://www3.towerhobbies.com/cgi-bin...&I=LXDYJC&P=ML

Traxxas Chassis Conversion Kit Low CG Slash
http://traxxas.com/products/parts/ac...30lowcgchassis
http://www3.towerhobbies.com/cgi-bin...&I=LXEAHA&P=ML

nimh will work on the brushless systems but the low voltage cut off will need to be disabled.

You should be able to make the jump to Lipo and brushless right away, its not that hard to learn to drive over a slow truck. Make sure the body is in good shape because you are going to roll it a lot but other than that its not hard.

I went from a slow crawler to a brushless 4x4 slash and some nice big lipos and wow is it fun!

I've had about every type of RC rig over the past 20 years, and the only thing I would even consider running a brushed motor in anymore is a crawler.

I have had really good luck with Castle products. Their ESCs can be programmed on your PC, or you can get a field card and do it whenever. For a 2wd Slash/Rustler/Stampede the Sidewinder series do a great job. Reasonably inexpensive, and if you get the SW3 (the latest version), it is water resistant, which for bashing is very nice.

With motors, you don't really have to worry about the sensored vs. unsensored issue with what you are doing. With that ESC, any unsensored motor will work great. The stock Traxxas "blue can" one is a 3500 kV motor. You can get a combo with the Castle setup with 3800kV, 4600 kV, 5700 kV, etc.

What the kV value on a motor is is the RPM per input voltage. So, for example, if you run a 2S LiPo battery (LiPos are 3.7V per cell, or "S", the 2S is a 2 cell battery), and a 4600 kV motor, you will run 34040 RPM (4600 x 7.4). The motors with "turns" on them refer back to the days when all motors were brushed, and it referred to the way the armature was wound. They try to assign a turn value to brushless motors more as a reference. I'd still look up the kV ratings on all motors before I buy them to be sure. So, when deciding what to get, you have to decide where you will be running the trucks. If you have wide open space, and a lot of straightaway area, a higher kV motor will get you more top end. If you have a smaller area, or a small track, or indoor track, then the lower kV is a better option.

For my Slashes, I ran Sidewinders with 4600 kV motors and 2S LiPos, and they were plenty fast. My boys are 11 and 7, and they work great for them. If you want to share equipment, then just get a 3S battery for yourself, and you will get a 50% increase in your RPMs =)

I personally try to buy ESCs new, because enough of the used ones have been overheated or mishandled. Motors on the other hand I've bought used and had good luck. You can also look on eBay, etc, for some of the second tier vendors (TenShock, HobbyWing, etc) for motors. I run TenShocks in a few rigs and they work great so far.

I'm not concerned about the speed of the trucks and learning to drive them. I'm not upgrading to lipo batteries right now because I have a huge stockpile of Nimh's that are still good batteries.

When I raced, Mamba was the general go to. If he plans on racing ROAR, LRP, or Novak are both good choices. I have Novak in my crawler with zero complaints. Mamba is cool, because you can tune it on your personal computer

The titan 12t that was in my son's slash died so I replaced it with the Traxxas VXL-3S Velineon Brushless Power System, it's pretty fast, and has held up so far. I think I got it for around $150 on ebay.

I just moved up to a 8.5T Novak got it at tower hobbie for about $175. Im running it in my Losi 22 buggy now that thing is fast. if your new to the Brushless world i would stay right around a 13.5T or 3800KV they have more then enough power i run a Castle Side winder 3800KV in my SCT and it flat out mover i have to tune it down for the track you can pick that kit up for around $100
