Lepton Build Videos Are Here

[n1troboy]

G'day Bob,
Just wanted to drop in and say great build videos. I have a few questions about the two test flights:

1. Do you know what ambient temp was when you did the tests?
2. what settings did you use on the controllers? (specfically timing advance and switching rate)
3. how much did you take out of the packs for each flight?

I'm in the process of building mine and am going to run the hacker a30-10xl on a jazz 55-6-18 esc if they ever come back in stock.

Keep up the great work

I am still working on my Trex 600 and I only flew one once last weekend. The Trex 600 flew great. They are different heli's for sure. Both fly well. The Trex 600 is great out of the box. The Lepton is going to need a tiny bit more tweaking (larger tail rotor blades and vertical tail fin) but it is going to be a great heli too.

The Lepton can still be flown in a park. The Trex 600 is a 50 size heli so you might get chased out of parks and really need a flying field.

Hirobo has GREAT quality in thier parts and the Lepton kit but this time Align does too based on what I am seeing right now in my kit.

It's an apples and oranges comparison however as they are different size helis.

Hard to say right now if I had to give one up for another. Hmmm.... at this point if I was asked to do that I would keep the Trex600.
1) Parts are cheaper
2) It doesnt need any more work or mods as it is 100% out of the box. Align really did a good job on this heli.

Looks varry nice. Are the align carbons for the 600 what you used on it? And if so do they work as good as the ones for the se?

[Finless]

No these were the Trex SE carbon blades not the 600.
They are a tad longer than the lepton blades but because they were stiffer the performance was better than the plastic lepton blades.
I also had to use 2 washers on each side of the Trex carbon blades.

Wow the lepton blades are that small. Well I like the se blades, run them on my x400. I get great tail controll and crazzy fast piros with'em.

Bob,

Both test videos are the same, What's up with that?

By the way, Awesome Lepton Build! You are the man.

What's the best 4S and 5S potential combo's out there from Thunder Tiger or others for Lipo packs for this thing? Assume a 900 - 960 kev motor is where it's at right? Any other gearing options available? I'm all over getting one I think. Also, will it fit the full GY401 '54 tail servo or can it be mod-ed?

Thanks guys....

I fixed the links on Monday..... They should not be the same now.

Hi Bob,


Great vids :clappp

1 question I wld like to ask. Do you have any tips on soldering the wire from BEC & ESC( the black & red wire) to the dean ? Apperantly, I have difficulty in getting both of the wire sticking together to the dean (male).

Thanks Bob

[Finless]

I have just the video for you!
See my soldering deans connectors video listed here:

Sorry to bother you guys again, but who is trying 5S on the Lepton and if so what TP or other packs and in what mah range? I would have thought it perfect for a 900-950 kev motor - no?

Hi bob,

Your video is amazing and very helpful. After asemble my lepton, I face the binding problem for full pitch. Instead of exchange the ball with stand and without stand on the seesaw mixer arms. I would rather exchange the ball with stand on the seesaw mixer arms to the pitch servo ball. I discovered that if by exchanging the ball without the seesaw mixer arms, it will cause the linkage between blade grips and the mixer arms are not vertically linked.
The pithc servo (Futaba 3150) mounted on the body is a bit inside, but by using the ball with stand, it will be much better in horizontal linking. I think that will be the best method to solve the binding.

Thanks
Martin

Agreed but the angle is so small it does not effect how it flys at all. I have flown both ways e.g. hirobo way and with the balls swapped and I felt no difference. So the slight angle appears to be nothing to worry about.

But your way also works because of the servos you used so thanks for sharing this approach!

:thumbup: Thanks Bob

I really enjoyed this lepton build. That thing flies great doesn't it.

I really enjoyed this lepton build. That thing flies great doesn't it.I couldn't agree more and it's not helping my lack of willpower in buying another heli :roll:

Need to convince myself - 'stop visiting helifreak, stop visiting helifreak' but you know it won't work :wink:

The main problem is that in the UK I'm looking at £430 for the kit, the hacker motor and ESC are another £125, a GY401 and 9650 are £130 so I'm up to £700 without ccpm servos, an RX or any lipos :shock:

Yes my US friends that's about $1200 bucks :shock: :shock: The lepton has the potential to be a $2000 machine at UK prices. Almost worth a weekend shopping trip to NY with the wife - no on second thought that will be MUCH more expensive :mrgreen:

Now you understand our frustration when someone complains they had to pay $50 for a 9650

Do you have a pic to clearify what you did? I am using the same servos in my lepton.

Thanks

[martinhung]

Here is how I convert the kit.

By exchanging the ball with stand and the ball without stand which are circled.

Pic 2 for correction.

[martinhung]

Today, I do some inverted flight and discover that the pitch servo (the front servo), there are some blinding after cover with canopy.

Especially when lowest pitch (-10), the elevator is blinded by the canopy. It's seem the servo horn is too close to the canopy. I have tried the both sanwa servo and also futaba 3150. They are blinded too.

I think I have to increase the lenght of the canopy stand to correction this problem.

[martinhung]

This pic shows how close is the servo horn with the canopy.

[Finless]

HmmI had not noticed that on mine but I will have a look later today out at the field.

Thanks for pointing that out!

The latest news from Hirobo:

Futaba
Pitch up : S3102, S3101,*S3150(For S3150, use servo plate from back )

http://model.hirobo.co.jp/english/index.html

[Finless]

Servo plate from back? Wont that make the servo stick out more?

Looks like the lepton is having some teathing trobles. I still want one after geting a 600 but will wait and see where it gose for a v2 or mods to solve problems.
