Tiny whoop Batteries? or Tom's 1st shopping list!
#1
Hi guys back with another link to, probably, ancient stuff. I have my shopping cart pretty much full, but of course banggood don't have stock of the E010 batteries I need so I have been looking for alternatives. I looked at the beeductrix 205mah batteries which look very cool but shipping to me here in South Africa doesn't come cheap... so looking for other options I stumbled upon these on aliexpress for a syma S107 heli.
1s (3.7v) 240mah 30c and apparently they weigh in at only 5.8g!
Obviously the connectors need to be replaced but what do you guys think?
$14 for 10 is a pretty price too!

So I'm going to reply to my own thread, I dunno who said "of course I talk to myself, sometimes I need expert advice"
That SOOO doesn't apply here!
I have found these motors on alibaba, min order 10, I guess CW or CCW makes it a min order of 20 but, that's still only $13.20 for 5 sets of motors...

Now for the good bit...

They are rated at 3v but have the same CL0620-14 part number as the MMW "6x20mm (speed : fast)" From the info I gleaned from a a search for Kv to RPM conversion the stated 43000 RPM translates to roughly 14000kv, the same kv rating as advertised on MMW.

Please, I am a complete newb and I am crap at maths, so feel free to tell me I talk Poop

I wouldn't trust anything especially battery from AliExpress... get them from trusted vendors Smile
they are so cheap probably because of low quality and low C rating.
as for motors, if you can you should go for the (speed: insane) one, the fast one is only a little better than the stock ones according to someone who tried, not worth the cost.

Ok, thanks Oscar! Whooping on a shoestring is more challenging than I thought!

worth a look - but doesn't cover MMW batteries Sad
I believe the Banggood 615's linked below are as fast if not faster than the MMW "fast" but I don't have direct experience (they say 55k rpm)

4X Chaoli CL-615 6x15mm Coreless Motor for 90mm-130mm DIY Micro FPV Quadcopter Frame Blade Inductrix

I !!THINK!! you can just snip out the two sides of that connector and slip in pretty much any battery - but you could reverse the polarity easily or you could just make adapters or replace the connector):

I wonder if the 260mah for the eachine h8 would fit: 5PCS Eachine H8 Mini H8 3D Battery 3.7V 260mAh RC Quadcopter Spare Parts
https://banggood.app.link/V0kG2OgPVw

what are the measurements of that battery bay?

first of all, don't get the Chaoli motors, they are nearly identical to the stock motors in terms of performance (even a tiny bit worse actually)

Chaoli are not great, just a cheap alternative to stock, if not using fpv gear. I've gone through a set with less than 5 hours use, won't be buying more, mylipo 205mah batteries work for me Smile

Thanks for the responses here guys,
@CesiumSalami, I will check those vids asap but have to get a new mobile ISP, hopefully today as I've got less than 250Mb data Cry
@Oscar & 2StrokeSmoke, I was thinking about getting the chaoli cl-0620-14's anyway after hearing that the new batch E010 motor's are down on power, even despite the 'flight times table' Oscar made. But this is the 2nd time Oscar has said 'don't do it' and now 2StrokeSmoke too, so maybe not...
I did find (on Alibaba again sorry Rolleyes ) a cl-0620-16, this last number seems to correlate to the Kv even tho Ali advertise in RPM's, (imperial vs metric 21st century style!) so looks like 1000kv less than the cl-0620-17 (speed : faster) MMW's. But of course only available in batches of 1000 Dodgy

@2StrokeSmoke, I have looked at mylipo cells, as I have heard only good things, also German engineering! I 1st looked for a possible upgrades for my, (hopefully) soon to arrive, powerup fpv too which uses parrot mini drone 1s, 15C, 550Mah's & I think 8.5x20mm direct drive motors, I will be asking for some feedback on a parrot battery hack but that can wait... Annoyingly MyLipo.de don't ship to South Africa and to send them to my sis in London and then to me will be double the cost of the batteries, New Bee Drone do ship here but is, again, the same as the cost of the batteries! This is the main reason I focus my searches on BG, Ali, and Gear best, free or cheap shipping and budget goods to *please the wife!* read ; piss her thrifty ass off as little as possible!

Also the fact that motors and batteries seem to be consumables in this hobby has led me to try and find cheap deals, But all you experienced folk cry in unison, Don't Buy Budget!!
Confused

Edit to add, those H8 batteries are also out of stock, I did check them out too!

I'm confused about all the shade being tossed at these Chaoli "fast" motors ... the MMW "fast" motors are only rated for 5-6 hours and cost sooo much more. I doubt the Chaoli's last longer but 5 hours seems within the realm of reason for a failure.

I mean I realize that the Chaoli's aren't better than stock - but they don't seem much worse ... 

Banggood 615's: 8.99 + 0 shipping
MMW: $23 + $5 shipping (that's a guess on shipping).

That's 3x the cost, roughly. Are they really that bad?

That being said, I think it's fine to say that the "fast" motors are not sufficient for Whoops .... is that mostly what people are saying?

So I have placed an order on BG, exciting times!
I found that the E010 is selling locally for 600 ZAR (South African Rand) which is over double the price on BG at the mo, so planning on selling 8 of them (hopefully they get here before Christmas) for 500 each (still just over double BG price) which will make me the cash to buy FPV gear... (Did I mention my wife's thrifty ass!?)
My order then -
8x Eachine E010 (red, mode 2)
and
3x Eachine H8 mini
The reason for the H8's..? If I order more than 8 E010's the shipping goes from ZAR 80 to ZAR 800, but it allows me to add these 3 H8's as well before the shipping makes the jump. So 1 H8 for me and 2 for my nephews to play, practice and race. Also looking at getting an 'ST-link' to flash silverwhoop or similar firmware to the H8 board, maybe hack it on to an E010 chassis when I order the next batch and FPV gear...

So BG shopping cart now contains -
1 x Eachine EV800 800x480 5" goggle (unless someone says rather go with the VR009?)
1 x Eachine TX01 25Mw integrated cam + TX (Thanks to Oscar's review & CesiumSalami's vid link confirming noise filtering)
1 x Lantian whip antenna (0.4g compared to 1g replacement fx797t cloverleaf)
and another
7 x E010's (1 for me to hack and another 6 to sell which will hopefully cover the cost of my 1st brushless build...)

Now I followed the link from RC groups H8 mini accro firmware topic to the ST-Link V2 but BG don't show a restock date for the item, can anyone tell me will this ST-Link work?

Also can anyone confirm if the battery connector on the E010 board and H8 board is the same? Should I buy a bunch of 1.25mm JST's anyway 'just cos they come in handy?'

Thanks again for all your help

The E010 and H8 do not use the same battery connector. The H8 is Losi the E010 is mcx or something? I'm not sure how the JST connector comes into play here - i assume those batteries you got have them? JST connectors have come in REALLY handy for me (all these cameras use them and i use JST connectors to avoid have to solder the camera directly to the board). Also the tx01 will come with a JST to Losi connector.

I can't confirm that that ST linker works though I'm inclined to think it will - but i ran into the same issue with the stock like ... months ago. I just searched eBay for "St-link v2 stm32" and picked one with good shipping. The connectors were in a different order but it worked on 3 boards so far so ... seems like it's generic enough.

On flashing the H8 - you will get a "blue board H8" which requires specific firmware and can only do acro OR level mode (both can run at low and high rates though). You can only change between acro and level by reflashing with a different variable set.

The contacts on the H8 for the linker are CRAZY fragile. I wouldn't solder on fixed, rigid pins. Like if you could strip the jumper cables on the st link you linked above that might be good... something flexible anyways. I'm using a one of the servo connectors / signal wire things off an ESC i blew up... i should probably glue it.

The H8 Blue Board is ... i'm sorry ... painful to flash with silverware. BUT it does work! It just requires the proper sequence (outlined in the github h8 blue page) and a beer (or a case). i never seem to get the sequence right on the first try - but after repeat attempts it always works in the end.

FINALLY - the H8 board can drive brushless motors if you're up for a project / fine soldering. I can dig up links for that if you're interested.

BUT REALL FINALLY- there are a lot of caveats up there but the H8 acro is LOADS of fun. Don't forget to pick up some dental floss to jam into the prop shafts when they start to fly off too often Smile

Thanks for confirmation they aren't the same.
I was still undecided over extra batteries and after researching further the (240mah 30c 5.7g) batteries I mentioned in the 1st post, I found 50 odd 5* reviews on BG I was almost convinced to get 20 of them ($30 inc. shipping on ali) and change all the connectors on the batteries and boards to JST's myself... Then I realised that this still didn't offer a charging solution for multiple batteries, plus lots of work, plus all the warnings against these batteries = just a stoopid idea Doh
Also found the (H8 260mah) ones you mentioned on aliexpress, $10 for 5 inc charger and shipping so getting those, still surprised they are practically 2g heavier 5.7g vs 7.6g tho!

Thanks for this, cart updated... Just know if it doesn't work, Mrs Thriftyass will be made aware that it was entirely your fault Big Grin

I thought so, I think the RC groups topic mentioned that the original firmware had to be deleted, which I guessed meant the same.

Once again very helpful info, I'm sure I have stuff to make something up...

I had heard its a pain, but any excuse for a case of beers eh!? Anyway if I start out with something hard it can only get easier, right?
Hmm sounds suspiciously like famous last words!

That's COOL! I will definitely be looking into this early next year...

I wanted to use a smiley like this Big Grin  but with Jim Carey style asparagus, 'Do I have something in my teeth?!'

Joking aside, thanks loads CesiumSalami for all your help and shared experience!

Oh and is it the Ladybird props you guys recommended for the H8? I've seen people saying positive-ish things about the tiny QX props too, any suggestions?

Oh, yeah, seems you are correct.
My original comes in at: 5.71g
the 260 at: 7.32g
Ummmmmmm dunno what to say. I've flown the stock H8 with 18g 750's (just for giggles) seems like it has some reserves.
I really like the 260's .. they may not be more powerful or more punchy (but i think they are). But they are just as punchy as the stock ones for wayyyy longer.

No probs. I'm happy to be your scapegoat ::bows:: also - being way over in Amurica - it'll be a long way for retribution!

Not exactly - the original firmware is lost and gone forever after update, true - but some silerware allows you to toggle between acro and level modes mid flight ... but such is not the case with the H8. You have to reflash in order to switch. But that's good... :: snags crutch away ::

The stock H8 has 6mm or something motors and the motor shaft is like .8mm or something so the lady birds won't work easily. Honestly - I just got a bunch of the stock H8 props.  It can handle other props ok - but the stock ones are good too provided they stay on Smile
Same goes for the TinyQX ones ... they'd probably JUST fit clearance-wise and are made for a different motor shaft. The ladybirds and qx90's are made for 1mm motor shafts.

Lol, you even have her South African accent down!

I had forgotten about the different shaft thicknesses, stock props it is...

Also had an idea to protect the inductrix / E010 ducts, I know its only like $1.30 for a spare e010 chassis, but rather than have to wait for delivery if the chassis gets broken, prevention being better than cure - install bumpers!

Bumpers made from 20mm or 3/4" lengths of drinking straw, a touch of PVC weld (plumbers glue) to hold the bumpers in place on the corners or wherever and voila (French word not large violin!)

Just reckoning that these quads being so light, that little bit of flex from the straw deforming before full impact should help. Additional weight should be minimal too but I don't have a jewelers scale...

I am also positive that this mod would increase flight time... working on the principal that it would look so fugly that the Earth would repel it!
