450 clone build

[philipjdall]

There are loads of cheap esc's on the market I doubt they went to the trouble of making their own 'clone' esc...

To the OP if you can't get it to work you'll be best off buying a YEP 45 and prog card as they work well and aren't at all expensive.

Where did you purchase the ESC from Mark? Wouldn't it be just easier to ask the seller the specifications of the ESC so you can find out how to programme it.

it came with the heli mate I bought the hole lot off eBay the seller had got all the parts and never built it

I will try the align instructions tonight when I get In hopefully it works as I don't realy want to spend any more on this budget build I would rather spend money on good parts for my next one

Why don't you message him and ask?

Right lads finally found out its a hobbywing 40a esc which I found some instructions for on the net and have now got it set up but would you take a quick look at this vid of the main gear and see if it's ok it looks to have a very slight buckle as it's going around don't no if it is just me being paranoyed or not

also got the swash leveled

You are saying it is warped?

I've seen worse warp than that and I replace warped gears. I would likely leave that on.

You can drop it in boiling water to flatten it but I have never had success with that.

Have you checked it for high spots too???

[Markmark.123]

I thought it would be chears
but
i never checked for high spots

It helps you get the gear mesh right.

Looks more like there is play in the mainshaft.
And that gear mesh doesn't sound right at all mate. Watch a video on YT for correct gear mesh and pinion height as that looks quite high too from what I can see in the video.
If you need any help gis a shout. Always happy to help where I can mate.

I'm not so sure, certainly not enough to tell from that clip. I can't see how high the pinion is either.


@Markmark
Can't speak for yours but the pinion is often meant to be about 1mm higher than the gear and with a warped gear it is harder to set but a bit above should do it.
As for the high spot is could be the run out on the mainshaft but I doubt it. Just about all main gears have some sort of high spot. Find where it is (it may be in more than one place) mark the spot (it may travel over several teeth or much more). Adjust the pinion to mesh at the high spot. It is hard to describe but I look for the tiniest perceptible backlash (play). When that is set the pinion should mesh nicely on the rest of the gear but not be too loose. It is very subjective but to help what I usually do is insert a strip of paper about 2 inches long between the gear and pinion at the high spot to give the clearance; the paper comes through looking like a concertina. It takes about three strips usually while I am messing about.

You obviously didn't look at the picture below then. The pinion is high. A lot more than 1mm.

I couldn't tell from that. The angle is awkward - I'd need a side view TBH.

You're right about the main shaft though it just seems to be the main gear that's giving off some vibration on marks heli there. I watched the video again and I was wrong about the main shaft maybe. Whatever it is though needs addressing as if it's vibrating that much on the bench it will only be worse once the blades are put on.

@Mark, have you considered replacing the main gear then if you can't get it straightened?

If that warp is causing the vibes the I agree it would benefit from a change. I found it difficult to see the amount of warp but if it is enough to cause vibes change it is right. I like clones probably because there are often issues like this to sort out and I have had branded helis that have had issues too but for a builder with limited experience I can see they could be a nightmare.

I still wonder what the mesh is like.

[Markmark.123]

I have just orded a new main gear I think it might just be easyer than sorting out this one

How's the build coming on Mark? Any joy yet?
Cheers,
