Where is the cheapest place to get Hubsan x4 spares and batteries in the UK?

JUMPURS · 15 Jul 2014 at 19:17

Got a Hubsan delivered today (after a load of drama) as i am thinking i might get a big quadcopter and was wanting something to try out to see what it is like and one of the rotors doesn't spin

a chinese 250 CF frame and CF props to replace the as the HQ props and the fpv250 frame as they are made of cheese!

Did you get a naze32? If so how did it fly?

I have the funfly naze32 on the 250. Directly halved the PIDs and it flew great.

Can anyone tell me what else I am missing for a 250 build please. Most of what I have ordered is copied from Rilot's build.

Ordered so far:

FPV250 frame
Hobbyking KK2.1.5
4 x Turnigy Multistar 1704 1900kv motors
4 x Turnigy Plush 10A ESCs
Turnigy Nano-tech 1500mAh 3S battery
Gemfan 5030 tri-blade props
Tunigy 9XR with battery
Battery strap

I am stuck with the following items on what to order can anyone help or send links?

Module and receiver (Would a FrSky DJT module with a FrSky V8FR-II 8 Channel work?)
Power distribution board
Wiring and plugs

Anything else? No FPV stuff for now.

Is a 250 frame hard to fly if you are a beginner? Should I be looking at larger frames??

Have you got a lipo charger? How are you intending to wire it up? Banana plugs? Have you got the receiver to kk leads? Lots of spare props and a led strip might be really useful for orientation ( did some LOS night flying tonight :-)

).

With a kk flight controller in auto level it's pretty easy to start hovering then moving on, I wouldn't got with anything bigger as bigger = more expensive. More expensive motors, batteries and ESCs, even the props which you will break a lot. Also consider a hubsan X4 to learn the ropes as it translates pretty well in the basics and is cheap as chips.

Also some great flying tips and learning process here

Sorry forgot to mention, yes I have a lipo charger.

Now I just need to know what I will need for wiring it up and what power distribution board to get. What do you recommend? I am happy to solder if that's better then using plugs.

Also what do I need to wire up KK to receiver?

I went ahead with a FrSky DJT module with a FrSky V8FR-II 8

Genoma · 16 Jul 2014 at 08:09

These look interesting. 3g flight controller.

I've just finished installing a 3g PDB which I'm happy with now. I had a 3.5mm banana PDB (too heavy). Tried a custom wiring loom (too heavy + looked a mess) but finished rebuilding with this and now happy. db_brennen is also using it:

For wiring you could solder anything in which case just get the PDB above and thin shrink wrap tubes. I'm running 2mm banana connectors on the motors to ESC, and ESC soldered to the PDB. You will also need a XT60 or JST connector for the battery.

The leads you need are male to male servo leads. I used 15cm ones like this:

Around 8 minutes with a 1500 but they are heavy and I'm looking for an alternative

Tried my 250 over the field and got around 9-10 minutes. Was around 5-6 with 3 bladed props.

Think I need to change some settings (gains probably) as it it takes a while to adjust direction in flight. Im used to my Vision being very responsive, unless the 250 is always like it. :confused:

Just need a light on the front now so I know what way its facing - very confusing!!

Rilot · 16 Jul 2014 at 09:16

What props have you moved to now (from the 3-blades)?

Cyclone · 16 Jul 2014 at 09:44

These, 2 sets.

I blame d_bredden

I did read somewhere that you get more flight time with 2 blades. Something to do with prop wash.

Thanks for the help and links. I ordered the power board, leads and some 2mm connectors. I think I have everything ordered now. Just have to wait a while for the few things I had to order from the HK int warehouse as UK didn't have stock.

Excellent, they are great fun. Did you get the XT60 or JST lead to PDB to connect the battery to?

Skeeter · 16 Jul 2014 at 11:17

With the HK FPV250 set being on back order, is there anywhere else that does a competitively priced complete kit (I have literally nothing except a transmitter and receiver), or is it best to spec up one in bits? Ideally as little soldering as possible.

I got some XT60 male and female connectors, I'm guessing that would do?

It's harder than a 450 imo. For me, everything happens so much faster on smaller craft.. .BUT it's a $9.99 frame, and props are cheap as chips. If you down a 450 sized copter, you'll most likely need to replace some of your 8"-11" props, possibly an arm, motor etc. Flying small gives you more confidence to go big, but I am not sure I want any more than 25cm any more

I can't count the number of times a tree has jumped out in front of my 250 and smacked it HARD, only for me to right the quad and take off again

Can't wait to try my new 250 carbon fibre frame this weekend. Was up late last night soldering on the motors/ESCs and somehow managed to get the back two motors wrong after spending ages testing and labelling :rolleyes:

All part of the fun
