Good starter Hex to trash

[Garry Spight]

After being hospital bound for a stomach illness for the last month funds have been a bit short.

If this ok as a starter setup a step up from my hubsan to start with.

I want to build a bigger hex to carry my eos m in the future but is this ok to learn and trash?


or shall i spend a little more on better parts individually

Gary, hope you';re better now?!
Personally I wouldn';t touch that with the proverbial!  KK2?? Nooooooo!  There are so many boards out there that are better.  I';m not sure what weight your eos is?  I think a 550 would be ok for some of the lighter ';compact'; cameras.
Better to put one together yourself I think.  What';s your budget going to be?

Cheers

DJI NAza Lite = c. £100-110

Just give you some ideas.   

For the radio control, Turnigy have several that come highly recommended, all for under £100 ( the TGY i6 is back-order on HK, I wonder why?!!!!)

I would advise you to spend a little more on the radio gear, it is an important consideration, and could be false economy to buy cheap, but twice!

Taranis, DX8/9 etc etc all good! ( give you loads more options for switch configs etc, and have a nicer ';feel'; to them, better gimbals etc.

[Garry Spight]

Thank you. Is the naza worth it. I looked at the cc3d?

Not fully fixed yet. Think I need a stoma bag fitted but not sure going in on the 6th for hopefully final op.

I know the radio gear is normally something to spend on. On my buggy I use the Sanwa mt4 which is good.

I will weigh the camera and lens but have a feeling it';s too heavy for a 550 frame

Thanks for the recommendations

[Garry Spight]

Just weighed the camera loaded with batt and card which is 543g so would need a gimbal and poss fpv gear on top of that.

How would I work out what is possible with that frame motor combo

Well, in that case, you';d probably be better of with something like a Tarot 690 folding CF frame or the like, but that ramps up the cost to the next level.  You would need 30a esc';s and larger motors, say 380-600kv.

Again, Naza Lite is fine for smaller craft, and may well be ok with the v2 ';hack';.  CC3D is an excellent FC, but has no GPS support, so not really a natural choice for an AP rig. 

[Garry Spight]

Thanks I just tried to order that cheap 250 to start a little flying with until I can buy the bigger frame like the tarot

I didn';t think a 550 would cope that';s why I wanted a cheap stop gap.


I will look at the naza will the v2 hack work on all naza lite with gps and what is a v2 cost compared to a lite

I';ve never used a Lite, only V1 &2';s, so I can';t speak for the ';hack';, but others on here have reported good success with it.  Only issue is, you would need to buy the PMU with the ';Canbus'; if you wanted to expand later, but of course that is optional, and you only need that if you want bluetooth, OSD, Zenmuse gimbal connection, 2.4 Ghz waypoint downlink etc, in other words, the full monty!

Prices vary, depending where you look.

I would be more inclined to go for a 450 quad, it';s not going to fly mega differently, will be much more like what you want to end up with than a 250 and will cost quite a bit less than a 550 hex!
A decent frame to go for would be the HJ Alien X format - excellent for the price!!!

I may try a 450 quad. I brought some esc off a member yesterday so that is a first step. Motors are next. The esc are 30A so how do i determine what size motor I need

2216';s are a good size for a 450. (980kv-ish)

[Garry Spight]

and would I use the same on a 550?

how do i determine power from the motor?

is there a easy way to do that?

[flybywire]

I do.
Amps x volts = Watts (power).  So, using 4 cell lipo';s (14.8 nominal v) at around 8 amps = around 120 watts of power/motor.  That';s a rough estimate, or you can use the ecalc tool if you want more detail.
Kv is theoretical rpm for a given voltage, so, 14.8 x 980kv =14504 rpm.  THis figure will help you chose suitable prop size, i.e lower Kv, larger the prop. 
The relationship will change depending on the voltage (number of 3.7v cells in use).

Thrust wise, I recall discussions somewhere about';s that suggest 2:1 power to weight ratio is bare minimum, 3:1-4:1 is ideal 5:1 is ';big fun';!
(not a technical term).

[guest325]

Sunnysky 2212 980kv are a nice motor for a 450 and a 550 hex, they usually draw up to 20A max so this would give you quite a bit of headroom for your esc';s (that';s what I usually do) borderline esc capacity is not a good idea!

[Garry Spight]

So what is difference between the 2212 and the 2216? which is the better motor? and what size props can you use on a 450?

It';s not so much ';better'; it';s just that various manufacturers make motors of a similar power in slightly different sized cans.  As I say, I have 2216';s working well on a 450 size quad and 550 hexa, with 4 cell lipo';s and 10" props.  Very stable and smooth (Emax).  T-Motor full carbon props, which are direct mounting.  Another consideration when buying motors, is whether or not they take direct mount props, as they are pretty nice!   

N.B If you standardise your motors on similar multi';s, you need to keep less spares in theory.

[Garry Spight]

right so the 2216 are max and the 2212 are sunnysky.

Direct mount props i guess bolt onto the motor spindle. How do the other type work?

are the sunnysky and max both direct mount?

are these the emax ones? is there a uk supplier for them?

Are these the same as the banggood ones? its says max on the pic but foxgood on the title.

Are these the right ones?

Well, they certainly look like the genuine item!  Good price if they are.  They are direct mount, but include the conventional screw thread adaptor if your props aren';t direct mount.
Can';t speak for SS';s as I haven';t used them!

N.B You can of course use direct mount props on conventional motors, but it kind of negates the advantages!

[Garry Spight]

Do I need to buy different direction motors or are they all same and just props different

[quadfather]

The motor hardware is the same.  Where motors are specified as CW and CCW they usually refer to the thread on the prop shaft.  The idea is that the lock nuts self-tighten on their respective threads.

You don';t have to buy different directions.  You could secure nuts with some thread locker, but if they are available I would go for it.

[Garry Spight]

wel the cw motors are another £5 each could you just buy the little bit that screws on the motor to replace that so its cw and not ccw?

[guest325]

Probably down to the fact that lh threads are more difficult to find!  Just buy the normal rh threads and use nyloc nuts - been using that formula since I started flying.

Garry, careful with the banggood sunnysky V2216-11 900KV motors, i brought some and the bearings are crap. They made so much vibration that i took it all apart and built something else.

Saying that, i have brought a total of 10 x 3508 motors from banggood and they all seem to be nice and smooth.

If you are thinking about a quadcopter, have you thought about a H4 680 ? They are quite large but can fold down to fit in a peli 1520 case. There is a good community on facebook with lots of build threads.

Im building one at the moment which ive calculated will have a good amount of flight from 2 low C multistar 5200mah 3S batteries.

Check out my ecalc (i think it will end up being lighter than i first thought, so even more flight time) -
