Anti vibration mounts. - DLE 35
Hey guys,
I am just wondering what your thought are on anti vibration mounts. I have a pair of DLE 35's that I am mounting on my Ziroli 101" B25 and I am just concerned with long term vibration effects on the plane. These are the mounts I have, http://www.6starhobby.com/engine-mou...pairs-set.html I have herd some say that it's not good for gassers to be mounted on anti vibration kind of mounts, but never found any definitive reason why not to use isolation mounts. |

I prefer to soft mount my engines when possible I have not had any problems from doing so and I'm using them on my new project.http://www.rcuniverse.com/forum/atta...mentid=2178377http://www.rcuniverse.com/forum/atta...mentid=2178378http://www.rcuniverse.com/forum/atta...mentid=2178379

What one has to remember is that there are two alternatives: Soft mounts and isolation mounts. The difference is quite obvious, soft mounts "Hyde or similar" are soft. They allow the engine to wobble in the rotary axis. Unless specified, many will also require engine nose ring fitted to the aircraft to maintain a constant trust angle. This isn't as easy as it seems with a glass engine and a detailed scale cowl.
The other alternative is isolation mounting... as shown in the previous post. These keep the engine far more rigid than a soft mount, but because there isn't any direct engine to airframe contact, filter out quite a lot of the vibration buzz. Definitely the way to go for a scale application IMO. Ive tried all types of soft mounts some years back in pattern aircraft. The Hyde mount was without the doubt the absolute best, resulting in a quite dramatic noise reduction. But they can induce a rather frightening wobble to the airframe at idle/low throttle setting. No problems for us but I'm sure it would, with extended use, easily shake the details out of you tail plane. |

So to be specific mine would be isolation mounts. I'm not concerned with noise cancellation, I'm more looking to take the edge off the engine vibrations to extend the life of the airframe. If they are not good for the engines then I will increase my inspection intervals.

Let me correct my nomenclator the mounts that I use dampens the vibration going into the airframe so that would be classified as anti vibration or isolation mount.

Holy smokes Wayne, that's quite the project. May I ask where one would go to purchase the mounting hardware in your pic ;-)

Sorry for taking so long to respond haven't been on RCU much lately. You can find the mounts here they have two different sizes.

Anti Vibration mount
You might need anti vibration mounts. Some are more elaborate than others take a look at this products, could be interesting:

Why Use Anti Vibration Mounts?
Anti vibration mounts play a significant role in the overall functioning of the various machine components. If you do not install these mounts, the vibrations could potentially lead to a breakdown or total failure of the entire machine. |

You would think so watching them run on an idle, but there are a lot of us that have been flying these things for quite some time now, with no vibration related structural damage. That pretty much proves no vibration mounts are necessary/required.
1. Thread revived from the dead (last real post was 2017) 2. This is the only post that the poster ever made. 3. Post was only marginally/generically related to the subject. Seems to be an awful lot of these happening lately. |
