 |
|
Has anybody had this problem... I am ready to finish up the electric aileron trim tab on my XL, but in testing I can not get the full + & - 25 degrees (as per engr. drawing). Down isn't a problem, Up is the problem.
I have "flush riveted" the first control horn, for clearance (which helps the down), but the 17mm travel on the Ray Allen servo doesn't give me more than about 10-15 degrees Up.
Removed the first horn and made new horn (moving the push-rod hole down a couple mm's) for better leverage. Not much gain in travel. I have also played with the position of attachment of the horn, but no real change there.
Am beginning to think Engr. drawing is incorrect, as to orientation of horn at connection (maybe it's upside-down). Drawing leaves much to desire.
Any advice or suggestions much appreciated...pictures would be nice.
Thanks,
Mike

Hello Mike:
I, too, saw this and after confirming I made my parts to spec I 'split the
difference' and had equal travel from both sides of the servo neutral (center)
position.
One flying I cannot imagine it will be a severe problem.

Mike-
When I was installing the servo in my HDS, Zenith said the setup was the
same as the XL- use the XL instructions.
Don't know if they've fixed them yet, but the pictures were flipped.
Follow the pictures and you're guaranteed to screw up the installation.
Can't say for sure if this is the problem in your case, but you might
want to check it out.

Hi Mike,
I went out to my shop to measure the aileron trim movement and check
the drawing and date.
My aileron trim is done according to drawing 6-ATO-1 dated 01-05. I
measured 32 degrees up and 30 degrees down movement.
Pictures are attached.
I hope this helps you

Just did mine and it deflects about 29mm measured at the trailing edge both
up and down. The only snag was that the clevis initially would bind against
the control horn at full deflection so I had to bevel inside the slot of the
clevis with a small bastard file. Now all is fine. The drawings are okay
IMHO, but a photo assemble guide section would be nice for future builders.

Regarding, 'Any advice or suggestions'....
Use bolts to attach the horn, not rivets.
The fasteners are loaded in tension.
Mine became loose in fewer than 100 hours.

OK boys and girls, you came through again. Problem solved. Clevis was binding on control horn, not allowing for full travel in correct position. A file, as suggested, solved the problem.
I thank you all, and now I can start growing the hair back...
Thanks again,
