Trimming help please!!!

Put first flights on Temporary Insanity. Made a lot of changes and after about the 5th flight I put in 2 decent but not great complete patterns. Problem is the plane feels light on the lines on the second overhead loop of the overhead eight, the first loop is fine and on the second turn of the hourglass which is above looking almost straight up. Now that I think about it most inside moves were uncomfortable, like the top inside loop of the verticle eight. It feels tight and pulls good everywhere else and even through the squares. Can this be helped by moving leadout position forward?
Thanks

Hi Greg,
Wish I could be of more help on the trim issue.
Add a touch more tip weight and see, then maybe slide the lead outs just slightly forward. Don't do both at once! hahaha
Could be bleeding off a little too much airspeed. (??)

On another note, have you used the Magnum 36 yet?

Hi Bill,
I was thinking of putting the 36 on this profile. But it turned out that it required something a little heavier to balance properly. So the 36 is on the back burner for now. I saw an Aero 36 fly this morning in a Trident. The motor ran a sweet 2-4 break swiching as the nose was lifted and back when leveled out.

Sounds like you need more power, or more energy conservation in your flying style. I always vote for more power, but maybe a better prop would help. Stalker .46, right? That's one of the problems with such a power choice, you're really working with no safety net...not popular enough to get anything but general suggestions. More info on your current setup might help indicate a direction to try, like more nitro, bigger venturi, boring out the muffler, or less pitch. Steve

PS: Really cool looking graphics. A somewhat darker blue would have been my choice. GREAT looking model. Don't get too frisky with it until you have it dialed in.

Hi Steve,
The Stalker was to light to balance the plane so I had to put an older OS 40 FSR, the one with the 3 piece case. This one has been modified by Tom Muggleton has a hemi head and really hauls the freight. No lack of power. Thru most of the manuvers and level flight the pull is firm and solid. Tried several props and the best seemed to be a 10-6 EW Zinger which surprised me as I never really considered them to be much. Has 1 ounce of tip weight. Equal wing panels. Lines are 63 ft. eyelet to eyelet .015 twisted. Thanks

Do you have a warp in your wing? How about a picture looking from the back of the airplane directly behind the center of the wing? Move vertically until the TE is centered between the top and bottom of the wing. Zoom out so the whole wing fits in the picture.

your post is a little confusing. The first loop of the overhead is an inside, the second loop is an outside. the second turn of the hourglass is an outside turn. If it is getting light on the lines or losing control on those outside turns I'd suspect a warp, a small one you might not see in level flight.

If it is also getting light on insides, sounds like you need more tip weight. Let us know what works OK.

Thanks Phil,
Yes you are right, I was not clear in my post. I was also flying in a rather strong wind and I forgot to mention it. The wind also changed directions 3 or 4 times during one flight. I know this sounds strange but it is common at the field where I fly (Sepulveda Basin). I'm sure that also added to my problems. I have checked and rechecked the wing for warps and can't see one looking from the rear. The plane flys the same attitude either upright or inverted with good tension. I need to fly it again when there is no wind to get a proper persective on the problem if there is any. I jumped the gun and was foolish to post so soon without putting enough time on the plane to establish a pattern, I got over excited, my apologies to everyone. I also thought it needed a little more wing tip weight so I will try another 1/4 ounce before I fly it again. I also will move my handle spacing out to 3 3/4 in. apart. The bellcrank is a 4 inch. I feel I had the leadouts to far to the rear as I was set almost as far back as it would go. I think my seconded time out I will be a little more relaxed and I will keep notes so I can can track where I'm at. Another thing that concerned me was the spinner I was using (not shown) but it was a Dave Brown aluminum unit with a heavy back plate and a heavy spinner nut and a 10-32 bolt thru the center to hold it in place. I don't know the weight of all this but just by feel you could tell it was way heavier that the plastic one I replaced it with (looked really cool). This will remove some of the rotating mass etc. I will try to get out again this week after work and report.
Thanks!!

Greg:

Had the luck to discuss the design of the plane with Windy shortly after I finished mine. The plane was designed have a more aft CG than is normal so removing the heavier spinner will probably benefit the flying. Mine with a 9oz engine without a spinner and a wood prop still needed (needs) tail weight. Moving the leadouts forward a little should result in better tracking above 45degrees especially if I understand you correctly and they are all the way back in the slot.
