Who here using a bearing at the end of their weapon motor shaft? Here at plum we have always, but i was looking at some hobbyweights and i didn't see a single one we any additional support other than the the motor's own bearings. Rick what do you use? rjw? Thanks for your help guys. -Alex

We used to use an outboard support when we used timing pulleys

Since we switched to smooth pulley over smooth drum, we no longer use the outboard support.

I think that without it, you might be fine, depending on your motor and what steps you take to make sure that it stays together.

I also noticed that all use timing belts and no outboard support...I think that a heavy drum is a better candidate for this than a beater tho...the drum carries more energy and can dampen a lot of the shock
jmo

btw: which bot(s) are you thinking of removing the support and with which motors?

also, if you are usng an outrunner with a 5mm shaft (for axample) check shaft hardness...it's possible that ifit's soft, you sould exchange it for a 5mm hardened dowel pin...like I do in little Sting

We have always supported it with a bearing on the end....

I just think it is safer????????

meh... on moving-around drive, I haven't really worried about it a lot. however, new fluffy's gonna have it. we put a bearing on the other side of the motor pulley to the drum, and it made all the difference!
