thank you guys. i really appreciate your entries... and pictures

i checked the specifications and has 148mm, that means
5.82 inches,
i asked you that because i thought i had to buy the DP metal stand off, but from the pictures above.. I can also use a piece of rounded Ply, right?

this is my first aerobatic, and gasser too. I only had a trainer, and I sold last week my GP Spacewalker.. at this time my hangar is ZERO planes (lol)...
so can you imagine how many questions i have about all this?

never mind.. I will get throught anyhow!
learning from experienced guys like you..

I checked your profile krazyc , such an assorted hangar you have! uh?
congrats..!

did i say thanks..?

see you guys soon.. on the flying field!!!

bye
