outrunner in 1/8??

[dodgydiy]

has anyone tried running a brushless outrunner in a 1/8 buggy, their revs are low ant torque very high, is there a reason for not using one??

Mounting can be a bit of an issue (depending on set-up), and they have more rotating mass than an inrunner. Also, due to the design they tend to allow for a load of dirt and debris to get into the motor, and the holes cannot be easily plugged.

There's no particular reason why they can't be used, but an inrunner is just more suited to the purpose.

could see the dirt being a problem, mounting easy enough really. was just wondering as i have a nice chunky outrunner and a hyper 7 hanging around.....

It'd probably work, you'd just need an ESC and LiPos et al.

ok sorry to kinda jack the thread but i know what an in runner motor is... i think haha... they are just like the motor which we usually run, u kno castle, tekin etc.. but what does and outboard motor look like? like one you would use on an rc car?

thanks,

on an outrunner the can rotates around the outside of the stator rather than spinning inside it. modified my rc18b using one driving directly onto centre shaft, giving a gear ratio of 2.5:1 and calculated what kv would be needed, this works very well. i will probably experiment a bit, have an 80A heli speedo and a 12 cell pack of eastpower 4200 nimh's. will try it out when i have time, if it works i can get a proper speedo and a good capacity lipo at later date. my current lipo packs wouldnt be good enough for 1/8 i dont think, they are 3600/30c. not enough capacity or current
