I think it's important to make folks understand that the Bud and similar cheapo mounts are dramatically different from a Hyde. The confusing thing is that they appear, at first glance, rather similar.
A Bud is, in my opinion, nothing more than a solid rubber isolation mount. What make it different to other iso' mounts is it's Hyde appearance, but it is in reality, nothing other than a !QUOT!giant rubber grommet!QUOT!, one side bolted to the fire wall, the other to the engine via T bar. Sure it looks like Hyde but it doesn't function in anywhere near the same way.
What Mr Hyde discovered was that if you take one solid ring attached to the fire wall and another similar ring attached to the engine the connect both together using a thing rubber membrane, what would actually happen is that when the engines throttles up, the two parts would separate and the engine would literally be !QUOT!floating!QUOT!... only connected to the airframe by the thin rubber membrane, not only really isolating the engine from the plane... but also allowing in to vibrate and move unhindered in the rotational axis. Genius.
Make a note that I'm talking the real Hyde mounts here, the expensive ones and not the cheap versions he's now marketing to-wards the hobby pilot which are very similar to the Bud, as ironic as it sounds!
Obviously there's a market for mediocrity.
Normally I wouldn't wade in on this topic but there's some factual inaccuracies stated here that should be corrected.
1. There is no functional difference between the soft mount I produce and market and the Hyde soft mount*, either in the way they are designed, the way they function, or in their performance.
(* - the original ~$125 Hyde soft mount, not the $60 low-efficiency Hyde mount recently announced).
2. The mount is not comprised of a "large rubber grommet" as described above, but from two symmetric disks made from injection molded, glass-filled nylon, and two pieces of thin rubber tubing bonded to the outer perimeter of the edges of the disks. The nylon disks serve as the attach mechanism between the airframe and the motor, and also to support the rubber tubes radially under torsional loading.
3. My last name is spelled "Budd".
