prop balance

thingiverse

this is a prop balance part like the dubro prop balancer,but i change the middle of the hole.and the hole’s diameter is 5mm.because the 450 helicopter's main shaft is 5mm.so you can use your 450 helicopter's main shaft to make your own prop balancer. enjoy yourself!and if you make it do't forget hit "like it" or "make it" thank you!
