--------------------------------------------------------------------------------

I'm installing a metal upgrade Swashplate... For the benefit of the other forum members I'll cover the assembly of the stock swashplate.

If you upgrade to the metal swashplate you'll also need to purchase the Cyclic Plate Guide Set (Y2170) this is the correct anti-rotation device for use with the metal swashplate...

Here's a pic of the parts for the stock swashplate and the upgrade Swashplate and Cyclic Plate Guide it uses...

Status: offline 		The Stock Swashplate Assembly...
--------------------------------------------------------------------------------

Set the brass center ball on a smooth flat surface, place the upper swashplate face up over the center ball. Make sure you're centered over the ball correctly. Press down firmly on the upper swashplate until you feel the brass center ball "click" into place. AVOID pushing on the outer plastic BALLS.

Next, turn that assembly over and place the swashplate bearing over the center hub, align it carefully and press into place. It is a tight fit, so some pressure is needed. BE CAREFUL NOT to apply PRESSURE to the BALLS... Only the center.

Now turn that assembly over and place the lower swashplate over the bearing and press it into place. The manual shows the use of CA glue during assembly, I use a pin to apply a very small touch in " four corners" around the perimeter of the plastic where it meets the bearing, using a magnifying lamp helps to keep the CA away from the bearings.

Another trick is I always put a drop of Tri-flow oil on every heli bearing. I don't care if it comes greased or not, I still apply that one drop...
BTW: almost every single bearing I've seen in a MICRO heli kit is shipped dry!

CA won't stick to silicone based oil. DON'T TEST THIS ON YOUR SWASH, The point is Dont get any CA in the bearing! I don't know about CA and other oils.

Here's the pics...

Status: offline 		Installing the Main Shaft and Swashplate...
--------------------------------------------------------------------------------

My first real tip for the MaxiR... I have a great selection of dill bits and after scratching my beautiful blue MaxiR SE Rotor Head, I was determined not to let that happen again and somehow find an easier way to insert the jesus pins in the main shaft. So, I measured the pin that came with my SE, it was 1mm, it's a tight fit in the aluminum Rotor Head and I had a dificult time measuring the ID accurately enough to be sure of its size(no pin guages here at home). So I took out a #60 drill bit, THIS is not a hardware store drill it, it's a bit sold for use in industrial applications, very precision, I chucked it up in my pin vise and bored the Rotor Head cross hole and the cross hole in the main shaft. What I found was the main shaft hole was already sized to 1mm or #60. But the Rotor Head was an extremely tight press fit 1mm. After boring by hand with the #60 bit in my pin vise, it was a perfect press fit with the included pin.

I did this same thing on this one before I even tried to instal the pin and no more scratches and a fairly easy installation(the perfect press fit), also no way is the jesus pin falling out. But I can remove it if neccessary.

After the main shaft is installed, it's time to install the swashplate...

--------------------------------------------------------------------------------

I've installed the Swashplate on the Rotor Head assembly, very easy, snap on the four ball links to the inner swashplate... Two ball links, one on either side of the Rotor Head on each end of the two Pushrod Long (Y0308) The other two of them are on the ends of the Double Ball Joint Pushrods coming from the Collective Mixer... Here's a pic...



On to the really good schtufff...

Status: offline 		Flybar and Paddles...
--------------------------------------------------------------------------------

You may have noticed the very short flybar I've installed in my MaxiR Standard... This is the flybar for the 3D Paddles... The stock flybar is pretty standard looking with two black paddles. The only thing I don't like about the stock flybar is it's not threaded but instead relies on a screw and nut clamp arrangement on the paddles. I'd prefer a threaded flybar w/clamps on the paddles. The 3D paddles are secured with setscrews to the flybar.

Here's a pic of the 3D paddles and the stock flybar and paddles...

Status: offline 		Tools of the trade...
--------------------------------------------------------------------------------

Here's a small selection of the tools I use to do fitting up of parts... An assortment of Moldmakers files, fine **** file, finishing file(approx like 500 grit wet/dry sandpaper). Scrapers and deburring tool. All of these tools are common in a machine shop, but I find them very usefull in my kit builds... The scraper and deburring tool are EXTREMELY sharp, they will cut steel and lay you open like a razor. They are made from hardened and sharpened tool steel.

NOTE the protective cover for the scraper(in red handle).

These tools are not expensive, with the exception of my moldmakers files, and can be purchased at any industrial supply company.



I will be using some of these tools in the build and will show you where and why and how.(Mostly the moldmakers files)

Status: offline 		Tail Part One...
--------------------------------------------------------------------------------

Here's a pic of the tail after installing the first bearing, use an arbor press or a small vise, be VERY careful. Here's how I did mine:

I started the bearing with finger/hand pressure making sure it was on the shaft straight. Next I put the shaft with the bearing pressed on one end between the smooth parts of my dremel vise jaws. Make sure the bearing is flat and flush against the vise jaws. ABSOLUTELY SQUARE! Slowly tighten the vise screw, VERY SLOWLY... The whole time you should be watching the bearing to make sure it's flat on the face of the vise jaw, you'll feel it "give" and press fit onto the shaft... As soon as you feel the shaft bottom against the opposit vise jaw stop. It's a good idea to stop a couple times during this task to see how far you need to go.... I have a large arbor press, but it's just too big, I think you can feel the bearing go on the shaft better with a small high quality vise than an arbor press. Take your time, it's not hard to do.

If you don't have a small vise, or arbor press I'm not sure what to tell you except at all cost avoid using a striking tool to do this. NO HAMMERS... you'll destroy the small bearing at the least and probably bend the tail shaft if you were to use a hammer. Maybe a "C" clamp would work too, maybe use a piece of flat metal on the "cup" side of the clamp. The small vise has always worked well for me, just go slowly. I've never bent a tail shaft.

Here's a pic...



Next thing to do is slide the Tail Distance Ring (small orange plastic spacer) onto the shaft...

--------------------------------------------------------------------------------

Here's an item every hobbyist should have in their shop... It's called a bench block. Jewelers use em, machinists use em. Hobbyists use em... There are just too many uses to try and describe to you... I'll just say it's indespensible in my shop... The holes in the surface are all different sizes and can be used for all types of work holding, shaft straightening, lot's O' uses... It's made out of cast iron and has a precision ground flat surface on top.

In the next step, I'll use the bench block to install the tail gear on the shaft...

--------------------------------------------------------------------------------

The next thing to install on the tail shaft assembly is the small aluminum "Ring of Coned Gear" This small part is designed to "capture" the gear on the shaft by creating a tighter fit of the small shank area of the tail bevel gear against the tail rotor shaft...

Status: offline 		Back to it... Let's install the "Ring of Coned gear"...
--------------------------------------------------------------------------------

Pay attention to the small bevel, it goes on the gear first, it's there to make it easier to get it over the edge of the gear shank, that's all. The ring itself is designed to capture the "coned gear" on the tail shaft... See pic...



BTW: The correct nomenclature for this type of gear is a BEVEL GEAR....I refer to the parts in my threads the way they are listed as replacement parts or in the manuals...

Status: offline 		Installing the ring... Take your time...
--------------------------------------------------------------------------------

First thing to do is to start the ring on the shank of the bevel gear USING ONLY YOUR FINGERS! Try to avoid using any tools on this gear, the trick is to get it on the gear straight. Your trying not scrape the plastic of the gear away(damage to the gear)... While installing the ring... All plastic gears are fairly easily damaged... Damaged gears will cause immediate noise and general problems throughout the geartrain...
