Default What Motor?

Hi, buying a Tamiya DF02 chassis kit (gravel hound) from tamiya, was wondering what motor i should put in there for general off road/beach/bashing was thinking of an 9turn motor (http://www2.towerhobbies.com/cgi-bin...?&I=LXLRE2&P=0) would this be any good? will be running the Novak GTX limitless ESC

Thanks for any help, Danny

Danny,

I would personally have looked at a brushless setup since the motors are sealed and beach running would have worked much better then.

A 9 turn is pretty hot motor, can the chassis handle it? If so, I would go with a checkpoint or trinity shock motor. something that doesn't gum up in the dust (V2s can gum up in the brush hoods) and gets long runtime between motor comm cuts.

Ultimately, a brushless setup probably would be best.

Assuming the cost of the GTX and a checkpoint motor, not too much price difference than just getting a Mamba max system. And you will need a lathe for the checkpoint still.

For a Gravelhound I would not put anything more then a 13T in it as the drive train will not like anything higher. Also if you are running it at the beach, I would not put any motor of any value in it as sand will find it self into ANY motor regardless of brushed or brushless and motors do not like sand. You may want to put some sort of breathable filter around the motor if possible, dirt is made up of primarly dust which is not as harsh but sand (silica) is very scaring for the comm and bearings.

ok i will have a look at the brushless motor systems, with the brushed motors what would the difference be with a 9t and something like a 15t ?

am i right with 9t has higher top speed and more torque and the 15t has faster acceleration?

Lower turns = higher top speed, less low end torque
Higher turns = more low end torque, less top speed

since you dont race i would look into a mamba max 4600. will give you more run time and is sealed. wont eat brushes up as it doesnt use any!

Yes, that is correct. I don't know the exact way it breaks down, but in general terms, the way you listed it is correct.

Heres a variety of motors. The lower the number the faster it is.
The slower motors provide more run time, the 5.5 or 6.5 might be perfect for bashing.

Great products.

the numbers on the mamba max are rpm per volt. the higher the number the faster it is. speed control can be programed by hooking up a usb to your computer and its 50 or more dollars less expensive than novak or lrp. only thing is though they are sensorless so they are not roar race legal

not too fussed about racing, i think im going to get the mamba max 5700, i think that will suit my DF02 and my TT01 for bashing, ill probaly buy a novak system when i get some more money, just want a decent motor before i go away

if you arent gonna race i think the mambas will be at least as fast as anything out there that is sensored besides all you would need to do is get a bigger mamba motor
