Hi guys... I just have a quick question... mostly out of curiosity at this point.

I am buying a nice used Trueworthy Pitts 12 that has a DA 150 in the nose currently. What i am wondering is if I ever decided to "upgrade" would a DA 170 bolt right on in place of the 150 or is the length, mount pattern etc different?

That's it for now!

Thanks in advance for any help!

Scott
