I'm running this swash plate and really like it. For about 8 months now there is no noticable play in it at all.
On to my question. While checking over my heli I noticed the lower mix arms rub against the inner part of the outer swash mts at full pitch + / - and cyc in the diagonal corners. And with full negative pitch(10-11 deg)
the swash binds on the mast collar.

Have any of you all using this unit experienced this problem? I have aprox 5.5 to 6 deg of cyclic pitch. I had to reduce atv's to 70% to get this. But seems I should be able to achieve 6 deg without rubbing at all..I would think. I'm going to shave some metal off the mast collar and try to put alittle more bevel on the inner mounts and see if that helps.

First of all, if the colar is aluminum, get rid of it . They break in the set screw holes. I'm using a Miniature Aircraft split collar on top of the lower mainshaft bearing. By putting the collar inside the frames, you will no longer interfere with the swashplate at full negative pitch.

Stuartn, have you noticed a reduction in roll since adding the quick plate? I have installed the ksj paddles and I think it still rolls slow. You can't increase the cyclic pitch much more than 6deg without causing binding...atleast on mine. I'm running 10deg @1850. She covers alot of ground making a complete roll.

Rchelial, thanks for the tip. So far I haven't had any problems with the set screws..I put a dab of finger nail polish on the edge of ea screw to let me know if one has moved. I'll check at my LHS about the split collars.

I have been running the Swahplate from the Quick of UK for better part of a year. Cyclic response is wonderful. Even with the standard paddles.
IMHO, they offer the best of the best, Jaguar of upgrades.

I used the standard collar that comes with the unit, and got +/- 10. Just adjusting the long links that go to the head. No problems.

Recently I ordered a set of metal elevator arms. these are adjustable, so I could move the swash up by like a Mil. Now I can get upwards +/- 12 degrees without problem. But I have setup my links to get no more than +/- 11 degrees. This is more than enough, even in autos. I use rocket city links so with the link butted against the metal A-arms you're set.

My Confiuration: With OS46 & OS50
Raptor 50 conversion-8.5 gear ratio, Hattori, 600mm Carbon mains, 85mm NHP T/R, Futaba Governor & JR Digitals ----
Also have the "UK" Fan Hub, Tail rotor servo mount, Horizontal anodized Fin Mount & Carbon Fins. Anodized boom and few other parts just arrived.

I am totally impressed with the quality and precision of the products of this ENGLISH company "Quick of UK".

On my next build I plan to use 2 mast collars between the main bearings to eliminate the interference between the swashplate and the mast collar. This should give quite a bit more room, only problem is that I will not be able to remove the shaft without splitting the R30 frames.

Stet, sure you will. Use the split collars that Miniature sells or Bergen. Then you don't have the setscrews biting into the mainshaft, preventing it from coming through the bearings. Also, with two collars, you have to thin them down, or there is elevator clearance issues. I thought maybe I'd run two, in case the Jesus bolt broke, you could still auto it in. But I make my own shouldered bolt . It's not likely to have a problem.

yeah the split collars would be better for sure now that you mention it, plus I may be able to remove them without splitting the frames.

As far as the elevator hitting them, I've ruled that out. Since the lever has to have clearance to rotate, the center part has plenty of room. What I did find however, is that I will have to open up the bearing retaining flange area of the frame in order to get the collars to fit up against the bearing races. So I plan to open those up partially and glue the bearings to one side of the frame. Should work out nicely.

Two Collars between bearings?

As for two Collars, I assume you plan on putting them between the two main bearings? Not sure exactly what that would buy, but you could possible get to the set screws by drilling a couple of holes in the frame between the two bearing blocks. That should allow access.

But a simpler solution might be to locate a longer main shaft, and use different/Adjustable A-arms.

Are you using the Quick UK Collar? I didn’t think there was a problem with clearance if you use it.

Even with the collar that comes with the swash, it does end up hitting at full cyclic at the bottom at some point, before the ends of the swash hit the frame. The Quick collar with it's tapered top is an improvement over the stock collar for sure.

And yes, a mainshaft with about 2mm more length would be a real bonus, perhaps the vendors out there will seize on this, I forwarded that suggestion to Quick UK. As we know, make an "upgrade" and they will beat a path to your door.

And yes, I would put the two collars between the main bearings. I just picked up two XCell split collars today for the task.

Do you think drilling a couple of holes in the frame will give enough access to the collars so that you can remove the main shaft w/o having to split the frame?

Also, I haven’t looked at the JR shaft, but I know the washout works, therefore, the diameter of the shaft should be the same. We might have an “Upgraded shaft” already sitting in the LHS depending on the length of the JR shaft. Just a thought.

I would have never thought of sending that suggestion to Quick UK. You would think they’d jump on any upgrade ideas.

By drilling the hole in the frame you will have full access to the screw. I've been using the Quick swashplate and one MA split collar for a year. Been working out great. Stet, I took the inner race of an old main bearing, thinned it out, and put it between the bearing and the collar as a spacer. Worked out well.

Al

That makes sense, you only need one, at the bottom? Guess I'll be using the second one on my second bird!!
