Hi Bill,

Thanks for the link. I've been following= it on the Homebuilt Airplanes forum; are you 'billsrv4' over there= ?

I've been trying to find a throttle mechanis= m in the video, but don't see one. Are they using the custom 'in th= e housing' butterflies, like the original Powersport engine?=C2=A0

Have you heard it run in person? If so, does the muffl= er work as well as it seems to in the video? (Hard to know how much the aud= io is clipped in level on a recording.)

Thanks,

Charlie
