This is quick and dirty mod that I believe is worth the few minutes it takes to perform it. Purpose is to reduce flexing.

To see how much the arm flexes, grab the end of the ball and hold the rest of the unit. Now twist it. It's like rubber. Noticed it when setting up the heli. The servo has no trouble flexing it.

Remove the elevator arm by removing the servo link, popping the vertical arm off the swash and removing the two screws securing the AH-1002 arm shaft.



Clean the recess in the side of the arm that the steel ball extension is screwed into with acetone. Fill it up so it slightly overflows with a good fast setting two part epoxy of your choice. Preferably not a flexable type. This is the key to adding the strength.



Let it set.

Reinstall.

The end result is much less flexing. And I don't mean a subjective difference. It's a major difference.

All of these little mods together should make appreciable differnces in flight qualities, not that they aren't already good.

I wonder how long it will take for the aftermarket companies to start making some cnc parts for the tiger. This would be a good part to make to totaly eliminate the flexing.

another similar route of doing this that plankers use to reinforce certain parts is to wrap wire or string around the part that is flexing and then saturate it in epoxy or CA. It's sorta equivalent to making a fiberglass like reinforcement

I hadn't really noticed this flexing, but I'd hedge to bet that it may be like this to allow some give in the elevator assembly so as not to put the full brunt of the swash's action to the servo gears. Obviously since the Pitch and Aileron servos are directly tied to the swash and they likely endure more wear and tear then the elevator servo.

It may be inconsequential. However, I do think that if you reinforce everything, aluminize every thing between the servo and the blades that while everything is more precise and firm, it's less resiliant to crashes, something has got to give. Aluminum snaps or bends and once it's snapped or bent, it's junk.

We're already working to make them out of aluminum. Too soon to say if the cost will become reasonable enough to justify making them, but I'll keep folks posted in case I pull the trigger on manufacture.

Meanwhile, good one hootowl . . . I'll have to borrow this one for the addendum sheet.

Thanks John.

Dan,

I agree. You harden too many parts and the craft becomes brittle. I'm not on a quest to make every part stronger. As I fiddle, some things jump out at me as possibly in need of attention. This was one I thought could use some toughening. To see the flexing, go into your elev atv and increase it beyond the mechanical limit of the elev and watch that baby twist. It really doesn't take much. I envision that thing doing that in flight when flight forces are applied against input.

I did consider the stringing idea before I saw the recess in the arm.
