RE: Engine Help for Classi Pattern Planes

Hi turbo,

ORIGINAL: turbo.gst

The OS 61 FSR used the #744 it was a bolt-to. This is the one that works with my later model HP 61 Gold Cup and Webra 61 Speed ( #1024). [...] I have used the BCM #161 and #162 mufflers. I like the #162 low DB the best.

Thanks for the TIP on the BCM #161 AND #162 strap-on silencers. I am sure they will be great for my earlier Webra Speed 61. If I get any noise complaints I will try the #162 low dB, but both fields local to me also host jet fliers so somehow I don't think my pattern planes will be the loudest there...

It's clear that a bolt-on silencer is needed for the later Webra Speed 61 and HP 61. If the BCM #4062 is a bolt-through then it definitely won't work. Thanks for the heads-up.

Best regards,

George
