Re: Repairs, Upgrades and things to look for.

I've been having issue with multiple pictures inserted in my replies. The spade response took several tries to get them inserted....

Here's the missing picture of the elevator chord:

Re: Repairs, Upgrades and things to look for.

Your rudder and elevator do look larger. Here's a tape measure on mine for comparison.

My ailerons are also about 98" long, one bay longer than the original.

Re: Repairs, Upgrades and things to look for.

I'm a couple of hours north of Ft Lauderdale, Vero Beach, FL74.

I've got my Laser apart doing a condition inspection, its a couple of months past due...

Let me know when you might be able to make it up. Maybe you can make some comparisons between my Laser and yours.

Re: Repairs, Upgrades and things to look for.

The last tidbit from the Acro List forum: The bent up ends were just to give the appearance of a stock setup to the untrained eye :-) They actually diminished the spade effectiveness. Here's a rectangular spade deflection sim. This is higher aspect ratio than the Pitts spade and you can see most of ...

Re: Repairs, Upgrades and things to look for.

More from the Acro List forum: My motivation for revising the spades on my B in the video was from all the test flying of the S-1S's and T's that were coming through my shop for rigging. Hopping in the B after flying one of those and it felt like steering around a truck :-) The setup I came up with ...

Re: Repairs, Upgrades and things to look for.

Here's a paste from the Acro List forum: Spade voodoo. First I have to say I’m not an expert if there is such a thing, but I have done a few, dug into about all I could find and quizzed those who have done more than I. The objective of spades is to get a mechanical feel by modifying the hinge moment...

Re: Repairs, Upgrades and things to look for.

I don't understand why you are so certain that the airplane is not nose heavy. The heavy elevator on landing is sure sign of a forward CG. Try landing a Cherokee 6 solo and then put two people in the back seats. Solo you may not be able to flair without adding nose up trim. Sevro tabs move the oppos...

Re: Repairs, Upgrades and things to look for.

Brian, Does your elevators have servo tabs like a Pitts S-2B? Some of the larger Laser elevators incorporated servo tabs to help boost the elevator. Are your elevator gaps sealed? I've come up with a tape method which is virtually zero friction. Building a new one out of steel tube and fabric would ...

Re: Repairs, Upgrades and things to look for.

Hi Brian, Sorry, I don't know who would be a good Laser guy out there to help you with your airplane. I was steered away from the large control surface Lasers just because of the heavy control feel. But there is something to check, where is your CG? The elevator getting that heavy on landing would s...

Re: Repairs, Upgrades and things to look for.

Hi Brian,
Sorry I didn't get back to you sooner, other distractions have kept me off the forum.

Congratulations on your new to you Laser! I'll dig around a little and see if I can direct you to someone in your area with Laser knowledge.

Post some pictures!

Dave
