My question about using a Hyde mount on an ARF like this is; since you need to attach the nose ring to a removeable cowl, how do you plan to attach the cowl to the fiselage. This isn't much of an issue with a hard mount, because the cowl doesn't tranfer much stress to the fuselage. I would imangine that the nose ring will put enough stress on the cowl, that the attacement to the fuselage will have to be beefed up. I'll be very interested to see how you address this. I don't think Hyde makes an ARI mount in the .110 size.

I sketched up someting that might work. It may be a little heavy, let me know what you think. You can get button head cap screws from McMaster Carr.
