Lepton build-up thread

[mudbogger2]

Thanks Will. Figured some others would like to see some of the parts of the machine so I decided to do the build thread. I always liked to see them before I built anything.
Hope you guys enjoy it.

Step 22. Main gear installation.
Here is where we get the tail belt setup also.

[mudbogger2]

Step 23. Boom supports and fins.

I left off the horizontal fin. I never run them on any of my machines anyway. Plus it saves weight right? :mrgreen:

[mudbogger2]

Step 24. Head, washout and swash install.

The bolt to hold the head on the mainshaft was in the bag #19 with the paddles.

I received mine a few days ago and I must say Jon's pictures do not do it justice. This thing is just amazing. The attention to detail is incredible. Everywhere you need to access something inside the frame has a hole (are you listening Align). One thing that also struck me are the mixing arms on the sides. There are little holes in the frame that let you know everything is lined up 90 degrees. I was also surprised at how strong the whole frame is once the heli is assembled.

Hey Jon, the build up looks good! I need to come over and check that thing out!

[supertrex2]

I thought this lepton comes with Motor and ESC. lol... Guess NOT!

[mudbogger2]

No motor, esc or battery are in the current kits. You will be able to buy it with them later on.

[mudbogger2]

Step 25. Rotor head linkage.

Get a set of link tools. You will be glad you did. Use the specs listed for the rods. Use a set of calipers for best result. Don't just lay them on the manual to try to eyball the sizes.

Lookin good!

MAN I would be done now if i didnt have to shoot build videos :)

You will probably be flying this weekend you turkey! I am getting my electonics tomorrow. For thew video I will be using HS85 MG servos and later with my AT 94761's come in I will convert to those if needed.

Actually the 85MG look good spec wise but they are not digital.

Jon that looks cool cant wait to hear how it flies

[mudbogger2]

Finally got caught up on things so I can resume the build.

I got some Futaba 9650 servos installed for swash controls. These are not the recommended size but I have another thread about installing them here.

Step 26. SWM-1 linkage install. I used some futaba large servo whells cut down to get the 12.5mm on the servo wheel. The Futaba servo drill
guide comes in really handy here. Also use locktite on the nuts holding the
balls on. Manual does not show it on thes linkage building steps.

[mudbogger2]

Step 27. SWM linkage-2.

basically the same as the last step. Make sure everything is square.

[mudbogger2]

Step 28. SWM Linkage-3.

[Finless]

mudbogger2,
we are now at the same place! I used the same darn wheels as they are black, look cool, and worked great.

I will have stpoes 26,27,and 28 video posted in about 20 minutes.

COOL... good minds think alike ;)

Step 29. Rudder linkage.

I used a standard 6 point servo arm with the ball located at 10.5mm for starters. May adjust this later after test flying.

[mudbogger2]

Step 30. Main blade assembly.

Be sure to check the balance on the blades. mine were off just a small ammount. Use the supplied blade spacers.

[mudbogger2]

Step 31-32 are setup steps for main blade pitch and throttle settings.

[mudbogger2]

Step 33. Motor installation.

I am did this step before I watched the finless video on it. :arggg: :arggg:

So I came up with an easy way to mount the motor after the boom and main gear are mounted.

Install 1 motor retaining bolt in the front of the motor. slip the motor in the frames and then install the back motor bolt. I then installed the pinion by slipping it through the top(it fits w/o much fuss). Adjusting the gear mesh required a modification of a tool! I cut a 2.5mm L shaped allen wrench down so it would fit under the maingear. Now I can adjust the gear mesh w/o removing the maingear.

[Finless]

Mudbogger, I am posting a video in about 10 minutes where I found a SERIOUS problem in the head linkages based on using the Hirobo addendum sheet that had the link parts in a bag.

If I could ask can you go full pitch and then work the seesaw up and donw and see if the mixer arm link are binding in the seesaw cut out slots.

If this makes no sense watch my video that I will have up in about 15 minutes.

Bob

[mudbogger2]

mine are not binding more like the letters on the link can rub the seesaw at the extremes.



you are talking about the spot in the pic here right?

[Finless]

YES... put full pitch in and see if the seesaw can TILT full diflection.... You will see it binds seriously. when tilting the seesaw.

Now put in some cyclic which move those arms even more and WOW rediculas binding.

I believe the edendum hirobo supplied has a problem. Right now i have flipped the arms back over and those links no longer bind in the sloit on the seesaw BUT the grip links now bind on the fatty part or BULGE for the thread portion.

I will take a video of the arms flipped and the results...

I am thinking that the arms should be flipped back and the ball with the stand off should be the one driving the grips.

Bob

[mudbogger2]

no binding untill I added cyclic. WOW. that could have been ugly.

[CRAZYKEV]

Both of you guy are doing a kick booty job and I thank ya'! :D

[mudbogger2]

Step 34. Speed controller installation.

Mine is still on order but shoud be here soon. I am using a Kontronik si I will not be using the supplied esc mount.
