ductedfan

I have a question that is driving me nuts!! I am getting ready to start building a ducted fan F-4 Phantom from plans. I want to re-design the tail section, so instead of having a fixed horizontal stab and elevator setup, I want the entire surface (horizontal stab) to move, just like the full scale jet. Any suggestions on fittings, hardware, linkages, etc??? Thanks in advance for the info...

Bob Violett of BVM Models built a pattern plane with a flying tail, the shrike. He created his own pivot device called a flying fork.

YEEE!

Trying to get that all flying anhedral tail will be a NIGHTMARE!

But hey, a good challenge is what we love, right?

Firstly I'd suggest making a mock up of the belcrank system. this will require separate pivots and separate pushrod/bellcrank setups for each tail.

If you take something like the BVM flying fork, and use just one half of it you'll probably be getting somewhere. This is going to be finicky and may take some machining but I don't think it's impossible.


Good luck!

how about using the setup used on the origional aircraft. there was a single actuator that connected the tail inside the fuse. moving the pivot moved the stab.

Check out the building manual for the Piper Arrow. This is an easy and stable way.
