Multirotor, multicopter and quadcopter discussion - The Drone thread

cheers mate, talking to some guys on the 560 forum, they say to not use the spacer that comes with the motor and to just mount it straight on to the frame
 
Off away for the weekend end of the month.. Do you think it would be possible to get all the bits and peices together for a FPV250 (minus the FPV for now) and get it flying?

I managed to get everything in less then a week including transmitter, I am now just waiting on a kk2, transmitter module and receiver from the HK international warehouse which should be here next week. I could have actually got those few bits in the UK if I paid a little more, which I'm now wishing I did because if I have to pay customs it will work out around the same price if not more!

I managed but as Ash mentioned, I paid extra by getting parts on eBay vs. HK.
 
Sorry about all the questions but going back the photo I posed of the motor, does that washer go between the motor and the frame as spacer or is it a washer to go with the nut that holds the prop onto motor? Can't find any images to see.
 
Its for the prop, from what I understand.

For anyone with an FPV250 sized quad that has avoided soldering, what connectors do your batteries use? The LiPos I'm looking at are XT60, and the ESCs use 2mm bullet connectors, but I can't seem to find any XT60 to 2mm bullet break out cables, and want to avoid soldering at this stage.
 
You don't get much choice, all the decent 3s batteries come with XT60s on them.

The HK kit comes with a battery with a JST and presumably the power breakout lead is the JST to 2mm one.

Does a 250 sized quad really need the 60Amps of a XT60?
Surely some smallish bullets will be ok?

No and a mini JST is much more convenient. Buuuut... Most decent batteries will have an XT60 connection. Personally I think they are great on larger rigs but a real PITA on minis :(
 
On ebay you can get a pre made PDB that has an XT60 and then 4 pairs of 2mm bullet sockets, which will be neater and have less unnecessary wiring than a breakout cable. I think I'll go with one of those.

Check the weight and dimensions, bullets add significantly and PDBs with bullets are often 50x50mm. On a 250, that's pretty significant.

I know you're trying to avoid soldering, but it really isn't hard and such a worth while man-skill to obtain :)

Have you bought anything yet?
 
I've given up for the moment. Even if I go for parts that need soldering I'm still going to end up spending twice as much at multiple different stores than I would at HK (if they had any stock :(). I've spent 3 days trawling the web, and even had a spreadsheet :D, but I've decided I'm not 'into' it enough yet to buy anything more than a quick and easy set, as there is always the possibility it ends up buried in a cupboard after a few uses.

I've stuck an email alert on the HK FPV250 kit to keep me updated.

Fair enough, I was the same when I was planning my first tricopter :) I was going to link a bunch of UK sourced stuff for you, would have worked out a bit more expensive and would have involved a bit of tinkering though. Always happy to help if you need it :)
 
Cheers for the offer. If I get hooked then I will surely be back for advice on upgrades :D

I have a history of getting into hobbies a bit heavy handed and then dropping them, so I've decided not to invest to much time and money in something I could well pummel into the ground on its first fight :p

I am slightly concerned that if I hang around too long though, that FPV will be illegal before I get a chance to try it :eek:
 
Heh... I will just break the law :/

Chances are, you will pummel it into the floor first flight. If not, then you are doing it all wrong :D

e: in the meantime, if you have an Android tablet there is a game called Quadcopter FX... for all my field trials, broken wooden arms, props, bent motor shafts on my unwieldy tri, this was the thing that got me "ok" at nose in flying :p As soon as it clicked, I haven't had a major down when flying LoS that wasn't me pushing it too far... With FPVing mini quads, the temptation to go low and fast is really strong, but they survive really well

^ Thanks for the quadcopter fx game/sim. Should help out on orientation.

I've got some 6x3 props on order. I think they're the largest you can go on a 250, if they are good I'll get a few more.

I'm curious, what's the second number for when buying props? I know the first is length in inches. :confused:

The second part describes the pitch, think the threading on a screw

For any given size, a higher pitch should result in more lift, but also more drag/power consumed

I run HQ carbon composite 5040 props on my 250s, find that it give an appreciable boost over more common 5030 plastic props without breaking the bank

I just got 3 packs of each of them. They seem better than the 3 bladed 5030's. I don't think I'll see much improvement then with a 6x3.

Thanks for the link, it explains the size very well.
