[NSRCA-discussion] Nose Ring

[Troy A. Newman]

I prefer the tighter nose ring. Keeps the thrustline shift in pulling and pushing corners to a minimum. The O-ring helps to dampen the vibration transmitted to the nose of the model. It the engine slops around inside the nose ring it will transmit a hard thump as the front bearing housing wobbles around inside the nose ring. Not only is it better on your airframe but it produces less noise this way.

Reality is Merle's mount absorbs the damaging vibration and the nose ring keeps it all aligned properly so that your thrust line doesn't change on you.

I tighten mine up regularly. I change o-rings a couple times a year to help this. Another quick fit is some tape on the front bearing housing of the motor.

   Either one will work.I would prefer a little loose.The gold nose ring isn't available any more. That is reason to sell the new solid alum. version.  Actually I run a Webra 145 with no nose ring The AR mount is stiff enough to do this with a 2 S.

    I think I sent the following to the wrong address. If so,my apologies.

    I have a Central Hobbies nose ring (the one that is silver coloured and tapped for mounting bolts).
    It fits my OS 140 tightly.

    I also have the older gold coloured nose ring that has a very slight amount of clearance between it and the engine crankcase
    Engine mount is a Hyde AR.

    I don't think the tight nose ring is the way to go,but I might be wrong.
    Anyone use this tight ring?   Opinions please.

    Thanks,,,,,,Dave
