Knife edge loops
 

Hey Gang,
I've been working on my KE loops. That last quarter of the loop sure is a killer ;) My question is on throttle managment. I enter the loop at nearly 2/3 throttle in KE. Then I punch it full and kick over full rudder. I find that as I near the top I almost nearly have to let go of all rudder input.
Should I chop back the power too? How about exiting though, don't I need to be wide open for a successfull pull out? What do you think? Right now the power is wide open for the entire porton of the loop.

Try entering at a reduced throttle setting, when you get to the 7 oclock, full power untill 11 oclock, off the power over the top, full power at 3 oclock untill exit.
once you get to 11 oclock you can be getting of the rudder only getting back one at the 3 oclock position. May be even have to add a little opposite rudder over the top to flatten it out.

A true mother F..... to do with any finess.
99.9% of thoughs you see aren't correct at all.
Just go to that U-can do -3D video clip to see a total failure.
You must have the correct aeroplane to pull them of correctly plus 30 gallons of spare fuel to start the process.

Practice it in sections. Try perfecting the transition from a nice controlled knife edge pass to vertical. Then from vertical to horizontal (over the top) Then from knife edge to vertical desending, then desending to knife edge.
You'll quickly notice that each section has a completly different set of demands/stick positions/mind set etc. Completly different to each other. They are infact 4 totally independent things.
Untill each one is mastered you'll never string all 4 together. Enjoy.

When you get to the lower portion bank the wings so your slightly inverted - just enough so most people woulndt notice. This increases side area and helps tremendously to get through the last quarter. Also with that you have a large increase in drag, so things slow down a bit there instead of speeding up.
Hope this helps

Ya,
I can fake it with the inverted trick. Takes Cahoonas to keep it vertical close to the ground. I'll try again this weekend...

You only Roll 1 or 2 degrees - thats all thats needed. It's barely noticable, and keeps it round without sliding through the bottom.

Speaking of Cahoonas, hasn't it been a tad bit cold in NY the last few weekends? A little too cold for flying for me.
