[NSRCA-discussion] Rhino Lipos

[Jeff Hatton]

I have been using the smaller (3s 2100 and less)rhino lipos in all of  
my electric planes and have been very happy with the results. I am not  
carefull with them at all (why bother when they average
About $8 each) and they are holding up to the abuse fine.

If engineers designed machines like lawyers make laws, you'd need to  
hire an engineer to operate even the most trivial machine.
