Model Forum / Radio Controlled / Air Models / August 2006An Ugly (but working) Solution
After taking some time off to experience intense back pain I took the Laird Solution out flying today. I blocked off the notch where the canopy isn't, and added about 25% more area to the vertical stabilizer (this is on a plane that _was_ a nice pretty black & yellow of the original -- now it's black, yellow and foamy white). It flys! I was right that it didn't have enough vertical stabilizer -- now it's a bit of a handful, but it does pretty much what it's supposed to instead of flopping around the sky for a bit before coming to earth somewhere I didn't want it to be. Whew! Now, do I try to make what I have look good, or do I just build another one...  SignatureTim Wescott Wescott Design Services http://www.wescottdesign.com Posting from Google?

Don't be like Mike > mk There's more wrong with it than just the wrong-colored stab, though -- I changed engine mounts in the middle of the project, and the fuselage doublers are pretty awkward, and the foam inter plane struts were way too wimpy and have balsa scabbed on them. Basically it's a pretty old plane, for all that it only has about 30 minutes of flight time on it. I'm thinking I should draw up plans for what it _should_ be, then rebuild it to that spec. It'll be prettier, stronger, lighter and replica table. But in the mean time I think I'm going to cut out a stab & rudder that are expanded by 10% all the way around, _then_ slap some paint on. And I'm going to make a clear canopy, probably after making a profile pilot figure. Then I'll fly that sucker!

Simply ignore the wifes car that doesn't run well, kids need shoes for school, and you're two months late getting the cat spayed... d:->)) >>I'm thinking I should draw up plans for what it _should_ be, then >>rebuild it to that spec.

The last three models I built (not counting the ARF) I've done with no plans, as a way of decompressing from engineering work. I think maybe it's time to do some planning ahead before I cut balsa...

Measure once, cut twice, and use quality adhesives on the splices ;-) >>>I'm thinking I should draw up plans for what it _should_ be, then >>>rebuild it to that spec.

Follow up: I knew that Bob Aberle had published a Solution article in the February '06 Flying Models magazine, so I read it last night to see if he mentioned any lateral instability. Guess what? His vertical stab & rudder are about 15% bigger than scale! Further, he mentions in the text that he tried it with the scale outline first, and it didn't fly well at all! Well, that's validation.
