Also dont forget to use the diodes from the titans or you will have horrible glitching problems

Forgot about that. Not having to worry about glitching with 2.4 will do that to you. As far as kershaw goes, I was just voicing my opinion that the dewalt is a better option than a single kd motor. As a matter of fact, some dewalt users on the traxxas forum use his "overdrive" pinions in conjunction with a 2 speed tranny to get over 40mph out of their trucks.

@Overdriven- So no diodes needed with the 2.4 ghz? That's cool! I never understood why they don't put 2 speed trannys in electric from the factory. What kind do you recommend? What's the selling points of his overdrive pinions?

Yea just like MonsterMike Dan has been playing around in this hobby for quite some time and has a pretty good idea of how these things work. He has allot of options available for spur gears and pinion gears and will gladly suggest the best idea for your preference.

I would put the diodes on the motors anyway, but thats your choice. You will have fun with using the Dewalt motor, and it will hold up well to most anything you put on it. They are a fun alternative for brushless and much cheaper. They are considered the novis choice and a great way to learn more about our hobby.

I didn't use diodes and suffered no ill effects with my 2.4 radio, but it is a good idea to do. Kershaws overdrive pinions are just really big. They are needed on some of his kits, and can be used with the dewalt too. The only 2 speed kit I know of for the erevo and emaxx is the traxxas kit. You should check out these threads, lots of info in them.

Yeah, I checked out that 2 speed kit on the Traxxas site and it looks like you need to manually switch gears from the transmitter not like the self shifting trans on my nitro trucks. What's up with that? Who wants to buy a 3 channel transmitter for that?

That is understandable, but I would think you get a low KV brushless system, that is not putting out the power but the torque, power it according.

Auto shifting 2 speeds are used on nitro vehicles because of the lack of low rpm torque produce by a nitro motor. It helps them accelerate quickly and also reach high speeds. An electric, especially brushless motor has very linear torque, and lots of it, so a low 1st gear is not needed. Some elec. models come with a manual shifting 2 speed to make driving in different terrain easier. Say you wanted to drive up a steep hill, you could shift into 1st and power your way up. But after that, you wanted to cruise down some trails, just shift it into 2nd and goose the throttle.

But a properly geared brushless motor and some lipos will tear off the line and make your pants heavy with its speed. :lol:

Dewalt motor in Summit is great!
 

Hi guys, I have have a dewalt 12 volt xrp motor in my summit with a Castle Mamba Max esc running a 4s 6000 45c battery arrangement. I started with a 14.4 volt Dewalt motor out of a new drill I have had for about 9 years. I ran an 18 tooth pinion with the 68 tooth spur gear, I then bought a 12 volt motor and installed it with a 16 tooth pinion running the same spur. I am very happy with both setups. The 12 volt gives me a little more acceleration and a little more top end but the gear noise is much higher with the smaller pinion. I can bash around till I get tired of driving (about 30 min) and put in about 2500 mah back into the batteries. The motor temp is fine (for a Dewalt) I can just hold my hand on it for about 5 seconds. The esc hardly gets warm,(the only way I could get the fan to come on was to climb my legs at a really steep angle in second gear for about twenty minutes) and the batteries are just a couple of degrees hotter than ambient temp. I also bought an 18 volt dewalt motor and I am going to try it on 6 cell lipo as well as the 14.4 volt motor on 6 cell lipo. I noticed that even though I am on 2.4ghz, my radio range was reduced to less than 1/3 when I didn't use the noise suppression capaciters on the dewalt motors, so needless to say I installed a pair of .1uf ceramic caps. onto the motor and my range returned to what it was when I had the stock Titan motor installed. I learned another thing about these Dewalt motors, the older new styles have a rear bushing and are single wound and the latest style has a rear ball bearing and is double wound. I put a drop of locktight on the rear bearing housing to lock the bearing in place because the outer race was spinning slowly in the bore of the rear housing when I was breaking in the motor. (this was a new motor). I am having an issue with the Castle esc. In brushed mode, the esc goes right to reverse instead of breaking first if you coast for more than about 1 second. I tried different settings and it is still the same. I installed the esc in my brushless e-revo and it was fine, so it appears that it only has a problem in brushed mode. I called Castle Creations and spoke to their techs and they said it sounds like a software issue, so I am waiting for them to get back to me with a software solution for the braking issue. (Nothing like coasting a second on asphalt in second gear after winning a race and then touching the brake and watching your Brand new Summit do an endo onto its roof and slide down the road!:gasp:) Well I broke in the body anyway!:tongue:
