Best motor for novafox and sand scorcher in off road use ?

[Supa Ryda 90]

Hi guys, recently i've bought a dirt tuned motor, for my novafox, and it turned out to be great and fast on off road especially on loose dirt, sand and off road terrains in general. Great torque and good speed, (i'm running with 16t pinion gear, the one that comes with the kit). So having also a sand scorcher, i was thinking to put the same motor on it, using the scorcher on sand most of the time. i know that the scorcher has two stock kit combination gears, so the question is i have to change from the 65t spur gear with 20t pinion gear to the 70t spur gear with 16t pinion gear combination ? may be better ? I was thinking also to buy a superstock bz, designed for off road use, but it cost a fortune, no problem to spend that money. In case i want to buy the superstock bz for the novafox and the scorcher, i think that i have to change the gearing, in particularly on the novafox. In the Scorcher case which gearing combination i have to put ? i can run with the kit ones ? and for the novafox?

thanks in advance guys.

The Dirt Tuned has more torque than the silver can motors, but slightly less rpm. The advantage is that it will pull a much larger pinion before the motor starts to struggle

and overheat. With the Novafox being such a light car you could probably go up several teeth on the pinion and ultimately it will be faster than with the standard motor.

 

The Sand Scorcher will pull the taller gearing option with the standard motor. But you are correct in that when running on sand the lower gearing will work better. With the Dirt-

Tuned motor's greater torque you may be able to run the taller gearing on sand without problems. Only one way to find out.

 

A Superstock BZ would be crazy in either, although with it's very high rpm you may lack the gearing options to keep the temperature under control, particularly with the Scorcher.

It may also be a good idea to replace the kit aluminium pinions with steel ones (The 15 tooth SS pinion is already steel). If you don't keep a close eye on the standard part it can wear very fast mixing aluminium dust

with the grease to make an abrasive paste that will wear out the other gears as well.

 

As a general rule you want to gear your car so that it is able to hit top speed on the surface you will be running on within a couple of seconds. After that it's simply a matter

of keeping an eye on the temperature. Smaller pinion will run cooler, larger will run hotter.

Not sure if the little plastic cover fits over the endbells of the rebuildable motors?

Sport tuned goes well in a sand scorcher, with the smaller pinion.

Another option is a quicrun 1060 and a 3s lipo... now that makes it peppy

This is my current favourite option with the re releases. 3 S on a silvercan or torque tuned and the 1060 is at the limits of most of the retro chassis so perfect, cheap and reliable.

Of course running a 3s with my BZ in my blitzer beetle works well too, I'm just not worrying about longevity, heat and drivetrain.

seen as come out from the kit i suggest no, maybe with a few adjustments to the case it will, in any case i have the anti dirt sock that comes with the dirt tuned, it's not waterproof but sandproof and dustproof almost yes. My pre configuration on the scorcher was the 540 johnson can with a robitronic 12t esc with a voltz nano 4000 mah 7.2v 2s lipo battery, so with the esc and battery i'm ok plus the battery stays perfectly inside in the waterproof case, the problem was the "motor", cause i'm in search of a great torque as i said before, especially on the scorcher that i use on sand and loose dirt, so the best option for me was the dirt tuned, worrying also for the heat, longevity and etc in a certain possible way. So what are you thinking about ? Same as the novafox, dirt tuned with robitronic 12t esc with corally 2s 4500 mah 7.4v. and it runs great. if i can i'll post a video of it. thanks for the helping.

ok, thanks, so the superstock bz it's very aggressive for this models, even if it has a very great torque, more than the dirt tuned and torque tuned. i'll stay on the dirt tuned. thanks mate.

As i'm worrying for the longevity, drivetrain and heat, running a bz as suggested by fuijo it might be to much for these models, so which is the best option between torque tuned and dirt tuned for you? i'm running with a robitronic 12t esc and a voltz 2s 4000 mah 7.2v lipo battery.

thanks in advance.

Maximum torque is at zero rpm and tails off as the rpm increases. So although it may have sufficient torque to accelerate quickly from a standstill, it may still never reach it's ideal operating rpm if

not geared correctly. So will generate more heat, drain the battery and wear the brushes more quickly.

exactly, so it will degenerate the motor longevity and capacities more quickly. so for you which is better torque tuned or dirt tuned for the scorcher ?

Well, i'm sticking with the kit silver-can in mine. When I ran it on the beach recently it was plenty quick enough with that and the smaller 15 tooth pinion. I ran it on a 7.2v nickel battery first, then

a 2s 7.4v LiPo afterwards. It was approximately the same top speed with both and certainly fast enough for me. After about 2 minutes or so the nickel battery reduced in performance where the

LiPo didn't. Also the LiPo made it considerably punchier and more fun to drive. It also helped to tighten the turning-circle dramatically by breaking traction under power.

If I was going to choose either of the 2 motors you mention, I would go with the torque tuned as it will fit without any modifications and should still perform on sand as well, if not better, than

the stock silver-can.

i'll go for the dirt tuned mate, i've tried it yesterday on sand on the scorcher and it delivers a great torque, much more compared to the torque tuned that i've compared. I need TORQUE ahahahhahahahha !!!!!

[oz-trash-cowboy]

Also depends what / who else you will be running with. If its other scorchers with silver cans, then they are all fast, but throw into the mix a brushless egress and …………...

That said, my RR got a 1060 on 7.4 volts and i love it!!!!!! 

[moffman]

I agree with Berman I've always used the sport tuned motor for my scorcher's and buggy champ and the ball diff make for a good combination especially for the Scorcher gives it a normal turning circle rather than the same as a articulated lorry! and a very good turn of speed without having to modify or chop anything off!

I have  Torque Tunes in my Super Champ and Nova Fox and is plenty quick enough

[swedishwiking]

I´ve used the BZ in just about all my models including the Sand Scorcher. No problems what so ever until the motor in my SS sucked in to much dust and finaly died after several years of bashing. I can really recommend this motor for the SS as it makes it a blast to drive. I must confess I´ve never checked the temperature of the motor though.

I use my NovaFox for indoor vintage racing. This means high grip surface (carpet in combination with minipin tires in the back and stagger cut tires in the front) and 8 heats of 5 minutes per race weekend (and some additional practice time). I'm running it on 2S lipo with a Kyosho G20 brushed motor (20T) and a 14T pinion and so far it holds up well. Three race weekends so far with no problems gears-wise, although they do start to 'sound' now. Might have to check and see if they're still okay  But the car seems to be able to handle all that power rather well.

[MAD RACER]

The thing is that in the SRB's it has to be a sealed end bell style motor like the torque Tune/ Sport versions due to the end bell bolts up to support the motor.

Therfore a Dirt Tune won't fit  as far as I can tell. My S/S box states only use the kit motor or a 540J version.
