Miniature Aircraft Nitro/Gas Helicopters > What links do you adjust for tracking on an MA head?

Just curious which ones you all use.

I would use the longer ones (finer adjustment). However, first I would make sure all you links are the same length. I dont think I have ever had to adust the tracking on any of my MA machines. If you have to anymore than about a turn I would Look over everything else (all links, bent spindle?, ect). Hope this helps.

Not all main blades track perfectly even if all mechanicals are perfect so sometimes some tracking adjustments could be required.

I've always used the short link but understand that at least a few of the team pilots use the long link. I would also like to think that adjusting just the small link will get you a finer degree of tuning. That is unless I have something wrong in my setup...

I have always used the short links for tracking. Then used the long to equal the upright and inverted climbout performance to make them about equal rates of climb.

IMO short links should be measured precisely to be equal and never get touched after that. All adjustments should be done to one grip through the long link(giving the fact you already did the basic pitch range set up). This way the pitch range is not affected. I hope that helped.

Just do it.

Pitch range setup on the bench does not equal the same collective response in positive and negative climbouts. I'm not saying what I do is right, I'm just passing on what Jason and Todd taught at a class. Any time you adjust a link you will adjust total range for the particular blade. Either way works, you get the same results.

Good stuff. Thanks. I tried first using the short links but they hardly change anything.

Hootowl,

If you have a split in the track that one or two turns wont take care of do equal and opposite turns to the short links. Provided you have the room ofcourse to shorten one of them. That way the change isn't so much on one side.

If I remember correctly, the short link will give you more precision because of how that mixer arm's center is offset away from the short link.

I would highly advise against using the "small" links, you are inadvertently modifying the mixing ratios by doing this when all you are really seeking to do is adjust grip/blade range. Use the longer linkage. Incidentally, which model are you flying and what type of head block? That is critical as the older plastic blocks have a static adjustment in the form of set screws which when set properly minimizes the chance of you having to tweek linkage lengths at the field. My 2 cents... what do I know?

I've always used the long links...for pretty much any head I think (one's I've messed with).

The short link is for center line of flybar to
center line of feather shaft, get them set first.
Adjust with the long link

What's tracking?

Tracking is the flying height of the blades. In a hover if your tracking is off you can see a disturbed disk or a "split" disk if one blades is tracking higher than the other. You adjust one of them buy adjusting the pitch of that blade only to get it to fly in the same height as the other. When adjusted correctly you will see one perfectly flat disk at hover.

Thanks Ben and everyone else. I think the instructions say to use the long links but I was looking for more input on it.

Long links it is.
