Multirotor, multicopter and quadcopter discussion - The Drone thread

It's OK think I am going to stick with them on as they are, its not that bad I guess

Just need to wait for my new motor to arrive

Today will be soldering the Naze, will have the double sided prong pins horizontal obviously and the rest vertically soldered.

Will also solder the ESC + - wires to the board, and start looking for a decent mounting position for my RX

I am in work revising today but planning on leaving in a few hours, got my 450 quad with me but its been raining this morning, not at the moment but hoping it dries a little and I will have a quick flight on the way home.


EDIT: its dry, time to do some flying :)

Re-edit of old footage from last year. Taken out about 80% of fisheye (100% looks rubbish) and added a little stabilisation. No colour correction done. I enjoy editing, but ain't very good :(

On youtube at 1080p

 
Thats some good footage you have there :), looks fine to me, im not so hot on editing either

Nice little re-edit there Flukester - certainly better than what I could do but then I have a good friend who's much better with video editing :D

Took my new 4S 6000mAhs out for a hover test yesterday - ran two together and got about 23 mins airtime with just under 4kg AUW!

Really looking forward to taking this to better places for video!

Am now going to be using the GoPro for my FPV feed as with the slower flying I'm doing the stabilized view isn't really an issue but will see how I get on.
 
Thanks.... yeah I fly most the time with GoPro gimbal view also, you get used to it and if not crazy FPV flying it's a much more relaxing flight :)

23mins is dam good flight time.... what size props ?
 
That's currently with 12" x 4.5" APC props but I also got a set of 11.5" x 5" Aeronaut CAMCarbon ones that I've yet to try ... need to balance them which I've just not gotten around to doing!

Am hoping once I've removed the FPV camera and possibly powered the vTx off the main batteries I'll lose weight and get a decent 15-20 mins in the air.
 
I can't speak about higher pitch 5" props although I have just ordered some 5040 gemfans for my QAV250 but 6" I have some experience with. I ran the 5030 on my tri to begin with but wanted more efficiency from my motors being limited to just the three on the tri, lift aside which is more, obviously, the throttle response is the most noticeable impact, it is far smoother and feels more linier.
I would imagine this would be much better for proximity flying and the best way I can describe it is you feel as though you have more resolution to the range.

I would google your motors and look for thrust tests, amp draw is increased considerably when you up your pitch or diameter so be aware of the extra load on the esc's; Each motor will be different in how it responds to the extra load and how hard it will work your electronics, this will go for total amperage draw form your battery's as well do the math and be sure the c rating is high enough for the total amp draw being demanded by the motors.

An example of the above are my motors, with the 5030 props my amperage draw per motor was around 7a, with a 6030 carbon prop it shoots up to around 11a which for most miniquad esc choices is on the limit of what they are able to supply.

No idea, I would say that they would probably add more motor load, but smaller props with higher pitches may use similar numbers to bigger props with lower pitches.


Whats a decent good all rounder and hard wearing prop that has some added thrust via pitches, need something thats durable for the DJI F450, the stock ones I have are doing a good job, but wondering what better ones are out there that are not going to break the bank.


Short session this morning, filmed from the ground so nothing exiting, does come with an angled to low flyby

 
It's for my tri plans. The RC Explorer kit recommends 8x5 or 9x5 props, but I want a stable easy to fly tri rather than an acro one so I'm thinking of going for slower spinning 10 or 11" props, but they seem to all be lower pitches.
 
Your getting in to pretty high amp draw territory there. I would say at those sizes you shouldn't have a problem, it's a very stable platform and at the stock size acrobatic isn't the main focus.
 
All of the ESCs soldered to the board, I need to wait for my replacement motor which should be here tuesday.

I couldnt do any Naze soldering today, my tip is far too gone and not good for soldering on the Naze

Was ok soldering my board wires though, new tip should be here Monday and I can get on with that.


Also started assembling my DJI landing skids, still some bits to assemble on there, but going together well so far, should be good when all the plates are fitted and everything in place

I mounted the model on top of it to see what it would look like (still with the white legs on) but its looking a beast :)

Maybe. Is a 10x4.5 going to be much more draw than a 9x5.
 
hard to say without proper thrust tests. you need to take into consideration cell count of the battery, prop size and motor used thohug as it all plays a part.

NTM Prop Drive 28-26A 1200kv on 3s with 8x4.5 prop is around 14a. on 4s it is 20a and with a larger prop will be more again.

This is a static bench test and under real use may be lower but it has to be taken in to account.

How heavy is the landing unit on the 450 DJMK4??
Click to expand...


Not actually sure, I will have to see if I can stick it on scales (if I have scales) it maybe on the ebay advert if you have have a look, I will try and search in a sec see if I can find the weight)


Doesnt feel too bad when holding it


Impressed with Makeitbuildit online store, ordered something near cut off time Saturday (new motor for my 250) and its arrived this morning

Still waiting for my new solder tip for my naze soldering though

Package weight specifies

Package weight: 333g


Compared to the weight of standard white legs which are around

Weight:90 grams

Yep, Phil is a legend for that sort of stuff.

If you don't mind me asking, how did you manage to pull a motor wire out? I've never managed that even when I snapped an arm on the 250 quad!

Was stripping a wire, but my strippers didnt strip it properly, instead of stripping the wire, it pulled the entire wire out (its not really repairable) but its only £9 so not a massive disaster.

Never had a problem with the strippers before

Will be installed later tonight. The ESC is ready and on the model, just need to mount the motor and solder the wires, thats all 4 complete then (unless I have to re-solder due to motor spinning direction correction)

It's funny how many different versions there are of that landing gear - the two sets I've got both have different plates (in terms of the placement of mounting points) for the gimbal at the front - yours looks to be different again!

A decent set of landing gear though for the few quid it costs - mine snapped at the connector with the bottom rail - the bit that clips on snapped away after a crash :/
