First Outside Loops from inverted

[Leroy Heikes]

Well I finally bit the bullet and did outside loops from inverted. I managed to do several all one at a time though. I have a question I end up recovering after the first one because as it is going up starting the second loop the lines start to go slack so I just pull out right side up and the lines tighten back up. I can do lazy eight after lazy eight and the lines don't go loose just on the second outside loop. What could be causing this to happen?

Have you checked to make sure the wings are level in both upright and inverted flight?  Also check the leadout position and wingtip weight.  If you are just getting started it does help to have some engine offset.  Most of all make sure you are down wind.  Later,  DOC Holliday

Kewl Leroy!!!

Now I have to try that one of these days.

Congratulations, you are at one of the most fun levels in the learning curve. Like DOC has eluded to the line tension problem could be one of many trim issues with the airplane or even with the way you are flying. Could simply be slowing down or stalling because you are not flying through the loops. Do you have a local with some trimming experience to help you make sure the airplane is in trim? If not maybe we can help, going to be a little tough trying to do it over the internet but possible.

I'll have to check and see if the wings are level the next time I go flying. Our club is mostly scale fliers who dabble in aerobatics with our everyday beater planes. Our good stuff never gets inverted. My poor Nobler is a little over three years old. It has been crashed (broken)  several times: once doing outside loops from the top (stuck in the ground to the wingleading edge, once learning inverted(busted into four large pieces) once when the clevis at the flap horn stripped, once when the clevis at the elevator horn lost the pin (pin completely gone), almost crashed at the RCCD contest when one elevator hinge broke and two others pulled loose( very low bottoms on my loops). I'm sure glad my scale planes don't have these problems. They only have technical difficulties when I get in a hurry at a contest.  My favorite one was at this years Nats, when I can not get my Ryan NYP(Spirit Of St Louis) started and run out of time.  The malfunction the fuel line was not connected to the engine. Boy was I embarrassed

HI Leroy,

It can be a trim issue, and it can be a "flying" issue.  Try to fly the plane further "up" as you do the climbing part of the maneuver.  Let the top just go on up there!  Keep it big and open.  See if the tension stays more constant.  It could be just a case of "too small" and bleeding off too much airspeed as most of us did when we were learning.  Are your outside loops from inverted as big as the outside loop portion of your lazy 8s?  A lazy 8 is much easier to fly smoothly especially if you're not getting "vertical" at the intersectons.

Do get a check on those wings being level.

Gentlemen;
    I flew the nobler this weekend. My observers said the wings are level inverted and up right. I did some more outside loops opening them up (once almost too much) and the lines did not come loose this time. It was fun opening them up because I would forget to feed the down back in when I was on the down hill side and had a real low bottom to the loop. I was told that my fuselage was lower than the tall grass that surrounds the circle.
