[NSRCA-discussion] Motor Mount Bonding

[mike mueller]

 I've recently switched from using El's mounts made in Canada to Budd mounts. The weight savings is 3 oz. over the Hyde type mounts. That's significant in anybody's book. Jerry also has excellent customer service and responds to emails which is refreshing these days. Seems to me that he has takin a totally proactive approach to fix a problem. Now the Monokote people are another story! Mike
