Ordered my lepton..
I got it for a sweet price from Madman, who has one already and ordered a second one. $500. I couldn't resist!

Now, Where should I get my Motor/ESC/Battery?
I will go 4 cells. Walts lepton had PLENTY of juice on a 4 cell.
Can somone help me out with motor/pinion/battery sudgestions?
Thanks =)

I would recommend getting the Jazz 80-6-18 ESC because it comes with a 4A BEC. You can order it from here... http://www.revolutionmodels.co.uk/

As for motors, the hyperion 3025 outrunners seem to be the most popular right now. I opted for the 12 turn as people say that the 10 turn is a little rough on the lipos. Also they are saying that it is a little to powerful for use with the 24tooth pinion that hirobo supplies, saying they had to run a low throttle % so they wouldn't overspeed the head. The 12 turn is a nice compromise.

As for lipos, Hyperion and Flightpower 3700mAh's are the ones to get.

I have a Phoenix 80 auto lipo version ESC and a Medusa 2A BEC on hand..
Does that sound good? I noticed Walt had a Medusa BEC on his.. but I failed to ask the amperage output.
Thanks for the help on the motor =)

yes that will work, since you already have it. If you are going to run all digital servos, I would get atleast a 3.5A BEC.

Thank you for the help. I will get a higher amp BEC.
would you sudgest 9650's for cyclic? Speed for cyclic I have found, isn't as important as toque to the swashplate..
I know JR DS micro digitals are nice.. but can be pricey!

9650 would be great, but need modification to fit properly. You can just use the 3150's as they just drop right in.

Use the ATX 94761 they are direct fit no mods required. They are digi and fast on 6V. If you are using the GY 401 use the 9254 and don't waste your time with the 9650 for the tail, the 9254 is night and day better than the 9650.

The 3150s are too slow. Check out the Airtronics Z94761. They are digital and alot faster and you can run them on 6V.

I like the 94761 because they smallera nd lighter and IMHO just as good as the 9650. You can run both on 6v. They both are fast and have plenty of torque. I guess it is up to you if you like Futaba or Airtronics, either way those are the best cyclic servos for the Lepton.

This heli looks solid so far..
I have to admit, the skinney frame cuts looked scary at first, but the hardware bolted down the frame good!

Some questions I run into during assembly..
Should I take the spindle and rotor blade grips appart and check for loctite and grease, or use them as they came? The rotor head block and blade grips/spindle came pre-assembled.

Also,
Is anyone actually using the clevis on the tail pitch slider, or did you folks swap it out for a ball link?
Thanks again..

fwiw...

Definitely disassemble and reassemble the head...Dampers need lube, some screws were questionable...Stock t/r rod is fine, no real need to modify...

Good Luck!

Be carefull if you take the pitch arms off the blade grips when you inpect your head!

I stripped mine down to ensure i was happy with the FACTORY ASSEMBLED parts and the tiny screw snapped off when i tried to take them out,leaving no chance to get them out!!!

Its now nearly three weeks since the UK distributer has had them back to inspect and have had no news of what they intend to do yet??!!!

Finished assembly last night. This really is a very high quality and well thought out heli.
Just need to outfit the electronics.
I'll post a picture or two later
I took off the spindle and greased the thrust bearings and applied oil to the dampeners and new loctite on the spindle. I did not take the pitch arms off of the blade grips. By the sounds of it, good thing too!
Thanks for the warning!

Now I know why my girlfriend approved of purchasing this heli..
IT matches her Teddy Bear!

I noticed the washout is a bit stiff on the mainshaft. The manual says to apply some lube. I did, but it still seems a bit tight. I'm sure it will loosen up after a few flights..

I agree with you about the quality of this little gem. The parts fit is the best that I have seen yet. I am about half way through with the assembly and am amazed ofjust how well everything is made.

I like how the flybar, flybar paddles and main shaft colar are all set with 2 set screws instead of one. Some other things I liked about the heli..

5 screws (main gear, and two tailboom clamp screws and fin clamp) and you have the tailboom out..
(2 screws to adjust belt tension)

Ball links attach the boom supports..

the tail pitch slider and whole tail assembly are one of the smoothest helicopter tails I've ever felt!..

the belt drive train is very efficient. I can see how this bird will auto already =)..

and the whole thing is very thin! Very aerodynamic.

you can count on some videos with this bird when I get it all dialed in.
The build went smooth, but my hands are raw from the screwdrivers and allen keys!
