Does anyone know the type/size bolt for attaching a spinner to the DA50s prop shaft?

Thanks,
Lee Snover

should be in the instructions, probably a 10-32..[8D]

Not that I could find, that's why I asked. ;-)

It is 10-32. Not that I read that anywhere, but I purchased a TruTurn spinner that claims to come with a 10-32 bolt... and it fit the DA-50 perfectly! I was worried that I would need some crazy adapter but it seems just fine as-is.

It is 5mm

Thanks guys:

Guess I'll have to check with DA to clear up the confusion. ;-)

Here is my email to DA and Daves response.


What bolt size, 10/32 or 5MM, are the prop bolts and
the spinner bolt on a DA50-R.

Hello
They are 5mm but 10/32 works fine for the spinner cone.
Stick with 5mm for the prop bolts.
Thanks
Dave

I have bolts for the prop, just need one for the spinner.

Thanks,
Lee

Finding out a 3/16 bolt will fit where you really need a 5mm is one of the things that really makes life wonderful.

It will work for the spinner bolt, but a 10-32 is about .006 smaller and will strip out if you use one in a place designed for a 5mm, like the prop bolts...
I gotta ask Dave why an engine made in Arizona, USA, uses metric bolts...
Yes, some of the parts are made elsewhere..The crankcases are made from 7075 aluminum in Tucson, AZ...To the best of my knowledge the ONLY model airplane engine cases made on a CNC machine from 7075, the best and most expensive aluminum alloy, not from CHEAP POROUS castings like some other engines...
NO, not all engine cases are CHEAP and POROUS...

Why not? The rest of the world (ie market) uses metric sizes.

I'm 69 years old, been a machinist and using inches all my life, this is the USA, the rest of the world can KM

Well, they say you can't teach an old dog new tricks, but I guess those that realize the new tricks lead to more reward are happier.

I prefer to divide by ten rather than figure out how many pecks are in a gross of bushels. Or how many ounces in a hogshead!

I'll take DA quality with the metric...or without![sm=thumbup.gif]

You got that right
