Moki 2.10 engine mount choices
I am mounting this engine in a H9 Cap 232g and am trying to decide between the H9 aluminum mount that has the rails grooved so that the engine can be slid for and aft on the rails, then bolted down. Or, am considering a Dubro soft mount. This is my first big scale engine, so I was thinking there may be a lot of potential vibration from the H9 mount directly bolted to the firewall, but have read lots of guys use them for other engines. Then I have read the dubro mounts are good, but there is some slight wiggle in the engine, due to the rubber stoppers. Some have failed. I guess the rubber stopper have to be peridocally replaced too. I can't decide and would like to mount the engine soon, so any help would be appreciated. thanks.

If you want to go through glow plugs fast and lose fasteners off of your engine, use a cheap soft mount. I care more about my engines than I do any airframe I'm likely to build or buy. But that is just me. The pattern folks have no choice but to silence their models. Other than that, I see no reason to bother silencing a model. Yes, full size aircraft do utilize soft mounts. But they have well paid engineers on staff to design their engine mounts and to control failure modes. We, on the other hand, do not. A bad soft mount is much worse on a model than a good solid mount. Ed Cregger |

I've had my Moki 2.1 hard mounted on my Midwest Extra 300XS for six years now with no evidence of any vibration-related problems, and it doesn't make any excessive noise. It is mounted using the Moki radial mount.
