Maidened Tiny Trainer

[AlvaFlightTest]

So today was the day I finally maidened my FT Tiny Trainer that I built from the plans. Crashed in about thirty seconds haha. It kept pitching nose down luckily still in one piece. Threw it up again and I had it all the way trimmed for elevator and it was still pitching down. I had pull back on the stick about 60 percent just to try keep steady altitude. Unfortunately I ended up crashing again into the only 1/2 inch standing water in the entire field. My electronics got wet for sure and are currently drying. Hopefully everything still works.

Besides the foam getting wet, nothing actually broke apart on the plane, thats nice.

As far as fixing my elevator issue, so should I just adjust my pushrod to give it more elevator so it does keep going nose down?

The picture attached is preflight.

it sounds like your plane is nose-heavy.

I think you need to double check your CG. Was CG exactly where it should be?

the aelerons look off in that picture.. they look almost flush at the tips but a solid foamboard thickness above the wing near the center. not sure what exactly is happening there, but there appears to be some sort of twist in them which might be reducing your wing's lift.

or the center of the wing is bend, which could be causing your angle of attack on your wing to be negative.

And it looks like the wing isnt flat on the wing saddle in the back. the stick or whatever that is is holding the back edge up. For that condition you need tons of up elevator to fix.

I think what you are seeing is where the rubber bands are bending the center panel between the ailerons down. I don’t think it is a big issue, I had the problem on my Bush whacker years ago, don’t think it affected anything.

I had it happen to me like that and it caused the angle of incidence to be down on the wing and it did cause problems on the tiny trainer.

I see exactly what your saying. The ailerons don't sit center from the tips all the way to the fuselage. Okay, that definitely looks like the issue. I'm really not sure how that happened during the build process, but I think I'm better off just making a new wing. Thanks You!

I see what you saying, that the ailerons aren't flush throughout the wing. I think Im just gonna build another wing to see if I can get it flush. I honestly don't know how that happened during the build.

Had this issue on my Bushwhacker, take a popsicle stick or skewer or two, and glue them perpendicular to the trailing edge of the wing in the center to reinforce it. Or rebuild the nose and put your skewers a little further apart.
