Re: Engine/silencer joint repair

Thanks for your help,both of you.I now know the cause,the timing was 12-14 degrees (I had used the original sensor mounting holes),but for the Rexl unit it should be 28 degrees.I have filed the mating faces and now making a bracket to support the silencer.

Engine/silencer joint repair

After 4 short flights,the silencer face seems to have melted,and the resulting uneaven face on the silencer has pitted the face of the engine.The silencer bolts were captive,the bolts were wired,and a gasket was fitted.The silencer is a Pitts type and although not very heavy has vibrated sufficientl...

Re: Leaking Dubro wheells

Peter,I have not tried cavity foam,I assume that it would collapse on impact,I was hoping for an expanding rubber foam.I think that I will have to keep waiting.

Re: Leaking Dubro wheells

Allan,I have tried that,the problem is getting the fluid into the tyre via the inflater.It then has to seal everything,yet still allow inflation,via the valve.I was hoping for an expanding spongy foam to fill the space where the air was,but still be bouncy.
