The BEC Pro is a good upgrade then.

Thank you sir, i just bit the bullet, now I can sleep at night knowing that my parts are on the way so that I can start my build While my son get's his Axial Wraith for his BirthDay next week. Thanks again Harley I will be posting up pic's of the build and my son tearing up the dirt trails and rocks.

I think you got the last one. Just looked at their site & they're showing out of stock on a lot of motors. I knew I should have ordered up yesterday before I went to work

is the wraith novak system worth it. is it all its supose to be. getting my wraih kit for xmas from the kids and want to start collecting parts .

Unless they have completely redone their programming then skip it! I'll try and see if I can see one in person. At this point I strongly discourage any Novak ESC.

The new tombuk2 has this"Rock Boost" feature that is supposed to give 3s speed on 2s lipos.. I wonder how many degrees of timing they are adding???

My buddy has a Goat 3S 18.5t in his wraith and it's really torquey but is slower than my stock system he uses 3000mah nanoteck 3s lipos i use a 2s 5200 turnigy hardcase.

Sorry slickwillie, when Harley gave me the confirmation on that set up I had to jump all over it. I'm pretty sure their will be more soon. If it will make you feel better I have'nt gotten none of the Axial Wraiths yet still waiting.

I don't take anything Novak says for truth. Look at the epic fail of the M2 dig. Their biggest issue is the drag brake on all their ESC's. They are using 20 year old technology damn near. If they are going to try and support crawlers they need to take a look at why the competition is stomping them into the ground in all cases.

Please understand that I'm not trying to p*** in anybody's cheerios, however I realize it may seem like that. In regards to the VXL system and the relentless amounts of hate it receives,.. I am not sure exactly when it did what to who, but I love mine.

For the record it was not my first choice but it was however a free choice. I did not wear my Traxxas panties and go shopping for it. I was killing brushed motors like it was my job and a buddy said here try this. Now high above on my Traxxas soapbox I will say in the last 2 months I've stuffed at least 150 4000mah 3S packs down it's throat and it has never wimpered.

If your stuck with the VXL-3s esc then you have this silly noob feature called training mode, and it's awesome for crawling, it limits you to 50% power and doubles the resolution of your throttle. So you can crawl on noob mode with 50% of too much, then go to the front yard hit the button on the esc and have 20+mph for open spaces. It's like having a manual electric 2 speed.

On 2S with 16/87 @100% it's a little faster than a jog, I use 2S when me and the dog go to the park for trail rides, still has plenty of wheel speed for trail running and buckets of torque. Crawling @100% on any S requires pretty serious concentration, a little to much input might send it into the neighbors yard. 3S is a hoot PERIOD well til it breaks lol. lf you happen to buy too much power and have a fancy esc you could just set the % of power you'd like to have.

Sure I miss the drag brake, but you can actually train yourself to hold it there with your fingee. Yes it's more difficult but it makes some not so enjoyable trails more fun as line choice and momentum are more critical. Also my Wraith spends a good bit of time with the wheels not touching and the drag only made it fall from the sky like a turd, unless I risk landing on the throttle and donating my driveshafts to the yard. I had it disabled on the stock esc,... do I wish I could just turn it back on? yes.

Cogging... I have 0 cogging, don't believe me? watch for yourself.

That's 16/87 with unweighted tires and the 3S 4000mah in the back. I actually recommend 14/87 for crawling but 16/87 is my do-all gear. There's videos of all sorts of different weights and gearing if you think I'm full of BS, watch them all! I need the views... check for cogging have a good time. Can I run 20/80 with no cogging? no, 18/87 is about the last of the crawlable gears.

Now I'm not saying for everybody to burn what the have and go buy a VXL. But if you have a buddy with one, or pick one up off ebay for 125$,.. I think it's a good buy. It's cheap, durable, waterproof, and has more than enough power. It's also rebuildable, and I have been told you can purchase a lifetime warranty on a new one from Traxxas for like 30 bucks, I don't know this for sure.

No one gearing is perfect for everything so don't be afraid to change it. Crawling takes gear reduction to reduce the strain on the driveline. If you want to have a dedicated crawler and only have a VXL, or an 8th scale buggy motor in the closet, just gear it to the moon. Start at 10/87 if that doesn't work RC4WD I think has down to a 6t pinion, couple that with a 90t spur and the 43/13 diffs and you've got silly gear reduction. The cogging is just a motor below it's designed RPM comfort zone, if you gear any non-sensored motor low enough it should eliminate cogging.

Changing the gearing is easy too, no really... you only need 4 chassis screws, I loosen the back 2 and remove the fronts. I only run the lower screw in my spur cover, all the screws can be easily reached by pulling or compressing the front suspension. I run 14/87 rocks, 16/87 rocks/mix, 18/87mix/highspeed, 20/87 for sand and parking lots, and 22/87 to clear the x-over at the track. I haven't ran all 8 screws since the beginning of October, I actually was testing gearing and forgot to put them all back in before I went to the track and broke the axle. So if I broke the axle with 4 screws and didn't hurt the chassis you guys not trying to break yours have nothing to worry about.

Bottom line... IMO If your the basher guy that's melted 100 bucks worth of engines and wants a waterproof 125$ fix and are willing to make some compromises then maybe the VXL is perfect for you.

Hope this helps somebody, and doesn't offend too many others

[redneck crawler]

Which motor and water proof esc takes the least amount of modification? Thanks for all the help

That's all good and all but the simple fact of not having drag brake makes the VXL ESC an absolute no go for me. I ran it in my Wraith at first so this is first hand info. I would not suggest it to anyone even at the $125 price point. If its free and you don't have a better option than clearly that's not really an argument.

It's missing the a huge part of what is NEEDED for a crawler/trail rig.

What do you mean? Your motor and ESC don't generally take any modification.

Manly the motor fitting the stock motor plate, the shaft being the right leanth and fitting an esc in the stock location I'm using an old nimh stick pack so I don't see much room for relocating the esc to the back of the truck

Even with a stick pack you could probably relocate but thats not a big deal.

The Holmes ESC or Castle Sidewinder would be best for drop in ESC's. However you would have to waterproof the Holmes on your own.

On the motor, just get the right gearing and there is no modification needed.

[madkawi650]

Just dropped a Traxxas 21t 550 stinger in my Wraith running on a Castle SV2 ESC. I have 20/87 gearing and the thing has gobs more torque than the stock 20 turn. Seems to be about the same speed, maybe a hair slower. But the low speed control is awesome.. $22 for a motor is pretty cheap. If it holds up for a while it'll be a cheap option for a fella who doesn't want to spend a bundle for more torque.. Best is, this motor was designed For 14.8volts so 2s is a joke for it and 3s should be no problem either. I was using it with 2s and its so smooth and quiet.

Just have to shave a little of the link mount to fit a 550 can in there.

Thanks for the info my stock esc just quite on me no lights no beeping nothing. I'm going to go with the holmes tourqe master esc do you think the jp customs 35t warrior would be a good motor for running trails?

Absolutely. That will be great motor for that type.

[Elliott000]

Im running a mamba max pro, but stock well second stock motor... I cant decide, i had a brushless in there but replacing parts became more regular than trail runnin lol, if i go sensored whats a decent high torque not so insane brushless motot rating.... Or whats a decent brushed motor... These axial cans only take so much of a 3 cell

Sensored brushless, about a 17.5 is a good mix. 21.5 is too slow IMO.

OR go with a 27 or 35 turn brushed. I run a 13t Crawlmaster which is about a 27t and it's fantastic.

[dogzpolo]

I would like to do some crawling but not a ton. I would like decent speed but still be able to go in water, so no brushless. I was thinking sidewinder or holmes esc, but i'm stuck on what motor to get the best speed with and still be able to go in water.
Sorry if this has already been answered before.
