Outrunner motor for 1/8th trophy truck?

[slimthelineman]

I ran an outrunner for a period in my two and four wheel slashes. Not the same I know but I was suprised at how a small motor could move them so well. The only disadvantage I found was the braking abilities of outrunners are sub par compared to an inrunner setup. If I wasn't racing I would not have cared the least. And they sound wicked when they run at high rpm. Tons of tourqe. I would say find a setup that has the kv for your voltage setup ie 30-40k rpm and around 1200w continuous at least.

Thanks for the info. I won't be racing so I could care less about the brakes. Do you think this motor would be enough on 3s lipo or should I get something with less Kv and god with a 4s set up because of the weight?

I'd recommend 500-700 size heli outrunner. I used one for awhile in my 1/8 Kyosho LM rally car. I also run the 600XL in a tunnel hull. My kv's were 1600 and 1650 on 4s.
Sounds tops.

Thanks for the input. I used the speed calculator and it says a 1600kv motor is going to get me going like 60mph on 2s though... I am using the AX10 axle ratio which may be different from the Wraith ratio which I can not find out. Does anyone know what the Wraith axle ratio is?

Do you mean wraith as in AXIAL? Anyway, have a look at this link as it gives you exact measurements of 500, 600 & 700 sized Align outrunners.
