I can only offer my 10 years of observation while using them as stated in my post # 780. Buy one, try it and if you don't like it through it in the garbage. None of mine are for sale

I also had a Dubro mount in a Goldberg Ultimate / OS 1.08. 1100 flights and the isolaters were worn out but still in there. Oh yes, after 1100 flights it still had the same cowl, same wheel pants, same servos, same switches. I did wear out 2 batteries and 2 sets of crank bearings though

I never had a 180 but I understand they can be a "shaker" maybe it might be better to mount it solid.
