Yeah the first post basically covers it. With a brushed motor you aren't going to get much faster then stock. A 13t Crawlmaster or 27t Torquemaster.

Ok thanks. that is good to know

How is the 18,5T Novak Goat 3S gonna perform? I'm currently running 3S lipo on stock motor and ESC, but the motor is starting to smell funny.:lmao: What I'm looking for is some more torque and maybe a hair more wheelspeed. I also want to keep some dragbrake, maybe like the stock. Or maybe go a totally different direction and go for HH BR-XL and a brushed motor, I'm really pleased with the performance of the HH in my Wheely king running 3S.

Stay away from Novak. Terrible drag brake technology. I have never ran a brushless I disliked more. if you want more speed then go mamba max pro and 13.5 Tekin. That part is covered in the first posts.

I can justify that is an awesome combo as i am running that. Swap the pinion/spur to the 32 pitch and crank down your slipper. (I wanna get rid of my slipper but what do you need? Not helpin if its cranked down, Eh. Dont really care losin a $5 spur gear once in a while) second thought don't crank the slipper if runnin plastic transmissision gears. still a really good combo.

For the money there are much better choices. It works but if you have driven the other systems you'd understand.

UPDATE!

Upped the gearing to 22/87 and through in a 3s lipo.. Yee haw.. Low speed control and lots of speed.
10 minutes of beating the crap out of it in my yard with about 85 donuts and 50 sliding power turns. Did some crawling over the wood pile and then checked the temp on the motor. 105*f and I used 600 mah out if a 3000 mah 20c 3s zippy lipo.
Broke the bumper mount when I crashed into my wife's ford escape, but other than that it was Awesome..
Highly recommend this as a cheap upgrade.

Started with a mmp & d317.5 (ok), went to hh11t alittle to hot it got but works great in my scaler and finally back to mmp w/ tekin pro4 3300 and for the 15min I played all I can say is wow !! Also went to 32p 12/54.wheely if u want and she seem to climb no problems on my little house course. True test to come this weekend!

I meant the Tekin 13.5& MMpro. Drag brake kinda sucks. I have the Holmes 13 turn and his Speedo on order. Tell John you video is good advertising.

Oh I got ya! Good deal ;)

After i burnt up a couple motors (the stock one, then a hpi 27t) i read up and changed the gears. i ended up with 87/18 48p and it made it crawl like a champ with another 27t, but it was slow. my 4yo could run faster than it. i picked up a 3s lipo today and threw that in. it crawls awesome still, but is fast like it was stock. after a good 30min of full throttle thru the leafs and 10 min in the rocks, the motor was warm, but i was able to touch it. a huge improvement. re-gearing should have been the first thing i did.

next is a holmes 13t and brxl (hopeing for a christmas present)

thanks for all the info everyone

I just smoked the another axial 20 turn on mine... Stock gearing, mmp and 3s. I have spare axial 27t im gunna thdow in temporary or until another smoke show lol. I wanna go brushless but my lhs only has a couple tekins now bout 110. A piece

Regear first.

Im not super familiar with gearing would i b aiming for higher speed or torque... Can u suggest a good pair to start out with

Try out 84 spur 16 pinion. The stock gearing is too high and can cause motors to burn up quickly.

I'm usin 32 pitch spur. 12/54 on the holmes 13 turn is to high?

No that's fine. He wants to use a stock axial motor which is just a lower quality motor then a handwound. Lower gearing will just help it last.

Im all for spendin 100 for a can, just dont want to fry it lol

I'd throw that Axial in and get the gearing where you like it. Then upgrade. If you aren't super familiar with gearing it'll be a great exercise to practice.

Question can the stock axial ESC AE-2 handle a 11 turn cobalt or is it limited to all 20 turn motors thank you.

I can't recall what the draw of the cobalt was. They were very amp hungry though. I would be skeptical. Also I'm not sure that a cobalt will fit.

Thank you,it does fit but I don't want to smoke anything."thumbsup"

@HARLEY - What exactly does a BEC do? Please tell me like a 10yo. I don't understand a whole lot about electronics.

(crazy how I bought an electric RC car)

Think of it kind of like an alternator. It supply's the power to your servo. The "stock alternator" inside an ESC (99% off all ESC's have a small BEC inside them) just can't power stronger servos.

The other problem is when you go up in voltage. When you plug a 3S lipo into an ESC the BEC inside reduces the amount of amperage it can put out. So even the stock servo can pull too much power of you go up in voltage on the stock electronics.

I burnt my motor and esc, i have a hard time trying to figure out the best option, i also have two lipo 2s batteries and want to be able to use them. Also i want it as a crawler but also i don't want to loose the top speed it has stock because in the place we play the ground is very soft and it needs some wheelspin to get the job done, and also i believe the stock gearing is adecuate for the crawling i do, any suggestions on motor and ESC?

Post number 2 pretty much covers it.

What about the stock ratios with the Tekin 13.5, will it work ok?

The stock ratio is going to be pretty fast with the Tekin 13.5T, and may not give you the low end control you want.

I just put in the Tekin 13.5T with 32P 56/12 ratio, it crawls very well, and on 3s lipos, is almost twice as fast as the stock 20T motor. On 2s Lipos, I bet it would still be faster than the stock motor.

That ratio is the ring/pinion ratio or the gear/spur ratio? sorry, newbie on this. :oops:
Where did you buy those gear/spur/ring & pinion parts?

It is the spur and motor pinion ratio.

I got mine at Tower Hobby, but places like TCS or RPP has them also.

This is what I used, but there are a lot of options.

If you're going to go to a high power motor, you're going to need to beef up the tranny gears, lockers, and drive shafts. Check out this thread, (post #2 has a list of upgrade parts, just to give you some ideas).
http://www.rccrawler.com/forum/axial...ys-wraith.html

Also, take the time to read the "Wraith Beginners Guide".

I am going to either put a Tekin 13.5 or Pro4 3300 in my Wraith and was wondering what i can expect with both. I know the 3300 is a torque monster, but will it have a much higher top speed? Shouldn't the 13.5 still have plenty of torque or would the 3300 do things the 13.5 can't? Either of these will be paired with a MMP and run on both 2s and 3s if that matters. I do want a more than decent top end for what its worth. I appreciate any feedback.

Post 2 basically describes that. You'll have better power and more speed. Either motor is good the Pro4 will have more torque.

Thanks Harley. What kind of runtime can I expect using the pro 4 3300 with a 2200 3s lipo?

Just depends on your trigger finger. That's a pretty small pack for a big motor like that. Maybe 30 mins as a guess if you're not full throttle most the time.

What size pack would you recommend?

It is up to you really. That pack will run fine as long as your lipo is good quality with a high C rating.

I run a very large 3s 5250 pack but will probably go to a 4000 in my new chassis.

I have a 4000 mah 3s battery with a Tekin 13.5 motor. If I do a mix of crawling and trail running, I can get over an hour of runtime.

i just came back from my maiden voyage with the pro4 3300 and mmp 12/54 running a 2200mah 40c pack and got about 40+ MIN trail riding on a hiking trail. i have lots of crawlers and r/c and have gone thru 2 other motors till i bought the pro 4 and all i can say is ijust fell in luv with my wraith after owning it for a month and a half.if u want speed and want to crawl like a 35t motor u will be so pleased with the pro4! it is worth the cake in my opinion but i will warn u u have to upgrade the whole drive line. i blew both f/r lockers ,i had mmp drive shafts already and gave it the full robinson racing tranny gears to.also added 4ws which is great improvement to. all i can say if ur thinking about this motor dont hesitate to buy it u will be so pleased but like i said dont expect the sttock drive line to last long. good luck"thumbsup"

Can i use a 2s lipo battery with the Tekin 13.5 brushless? in the Tekin webpage says 3s, but i have 2 2s lipo batteries that i want to use instead of buying new ones

Yes, some guys have run them on 2s batteries, and is faster than the stock 20T motor. You would want at least a 40c battery.
