RC Planes

How many amps do servos draw Bigpops?

My understanding is that you need a separate BEC to drive the servos, as when the ESC can't cope, through drawing too much power, there's nothing left to drive the servos, thus leaving you with a plane you can't control.

The one I've ordered (which has still yet to ship :mad: :p) has 4 x 9g servos, with a 30a ESC, which is supposed to be pap. Just wondering if I should get a higher amp ESC that I could keep if I choose to get something else later down the line, along with a BEC?

Are BECs wired in between the ESC and batteries?
 
Wow. In comes the big boy. :D

That huge plane looks epic. Is that one of those 3D planes? The prop looks like it would happily chew through your arm.

The depron foam plane - how easy is it to put into shape a plan you get online? I'm guessing the fuselage is the easier part, but the wing, how do you ensure it's aerodynamic and provides lift?

Would you be able to make a flying wing out of that stuff?
 
This is quite annoying, I order from Giantcod the FlySky transmitter on the same day that I order the programming board for it from Canada, and the programming board turns up before the transmitter. :o 6,000+ more miles in less time.

I've also just realised that my postman is signing the Special Delivery receipts of evidence for me. Think I might complain... grrrr... :mad:
 
Yeah that Cessna - and that big mother that Taggart has - :eek: :eek: :eek: :eek:

I remember dreaming about having stuff like that when I was young, but everything was so expensive that it was so far out of reach I could never see myself getting one.

How much do those things weigh when they're in the air? The one I've ordered is 1600mm but it's made of foam and hasn't got any detail. Those things look brilliant.

Taggart - very handy you are indeed :cool: - I've been reading about balance charging and what not which is why I got onto parallel charging. I've gone and ordered a server PSU - LOL - to convert to a 32amp/400w lipo charging PSU. It was a tenner all in. Might be a bit excessive for the $20 Turnigy charger I've ordered though, hehe.

The last thing I need to sort is an ESC as the one that comes with it is supposedly pap, and then some parallel charging leads, and I can't work out what ones I need for that. More £££ though... :o

My MX2 further up has a DA50cc in the front and all up weight is about 7.5Kg, will prop hang all day long and is a joy to fly, wingspan is 2.2m, the carbon prop is a Mejzlik and are about £60 each, ive gone through quite a few nosing over on landings, so now use the Weiss wooden ones at about £25 each. The whole model stand me at about £2000

The extra is a Comparf extra and is made of composite rather than built up from wood and skinned, again has a DA50 and savox servos, this one stands me around £1800 quid. Gets very expensive if you have a crash :( But its oh so fun!

Got any videos of you prop hanging that thing? Let's get involved. :p

Expensive stuff indeed... I'm now nudging £300 and all I've received so far is a tiny £9 replacement motor and two replacement props. :confused: :p

Just wondering if you are going to try to fly the plane you've bought before ripping out the servos, motor, ESC and replacing them?
Just curious as it should fly perfectly well to start with as that is why it's being sold almost ready to go.

Yeah I'll be starting with it as it is... I ordered it on the basis that it's pretty much ready to go, but as I've been reading and getting more into it I've just been buying little upgrades for it, so if it fails I can swap it over.

FPV is what started me off, but the more I read about it the more expensive it seems. On screen displays showing exact locations, speed, altitude, battery voltages, mAh used etc seem to be the norm, they even have autopilots and return to home features which seems pretty mental. :eek: Also there is datalogging associated with that, so you can load your flights into Google Earth and all that. People with 20+ mile roundtrip flights seems the norm with the right kit also... crazy.

I've wanted this for a few years now: http://www.top-flite.com/airplanes/topa0300.html

I've never had my own plane, but my Mum's previous partner (going back to when I was about 8 here!) was well into his planes, we used to go flying at a local club most weekends. I'd love my own like the above one day :) But I don't have the time nor the money right now sadly :(

That looks chuffing brilliant.
 
Wahoo, finally got some post! Not delivered to my door of course, we were in when delivery was supposedly attempted, but no knock or door bell used. Interesting.

Anyway, got my GiantCod order through:

Flysky 9x 2.4ghz transmitter and receiver
6 x 9g servos
A bunch of props to play around with :)

That's a 2212-06 motor (whatever that means lol :p) with a 3 blade 8x6 prop. I can see that prop murdering the motor if I run it too hard.

What do the numbers mean on the props by the way? First is diameter, second I presume is pitch, but which way do the numbers go? 6 is more aggressive than a 4, say, or the other way around?

Awful photos due to me still running with an iPhone 3g. :o

Also, Smartieparts board for flashing the firmware of the FlySky 9x. Includes the micro USB connectivity and a backlight for the LCD display - which looks like it'll be really useful.

That AXN Floater looks very similar to mine, Bigpops. A EPO foam pusher thingy. :p

Where did you get it from, and what did it come with? Motor, ESC and all that?

And what batteries were you using for flying that long? 25 mins is a long time!

And... :cool:... how are you setting up flaperons? Are flaperons a way of using ailerons as flaps, or is it a combination of the two? I want to set the flaps up on mine when I've got it, guess it'll be easier to land and what not, but I need to cut the flaps and then fix some tape across the hinges to stop them falling off - that's what I understand is needed anyway.

The transmitter is supposedly pretty good for the price, saitrix. Makes a horrific beeping noise every time you press a button though which is already doing my head in. :p

Blimey, all stuff is VERY confusing to a complete RC Plane noobie...

Is there a starter kit I can buy which has everything I need? And then can build on etc??

It does seem completely daunting when you first start reading, but it's not that bad. What I've done is order something simple, and then in the process of reading started ordering other bits to either upgrade or just give me alternatives to the setup of the plane.

Like I say, I'm still yet to receive anything that will actually fly. ;)

Look around for something that only requires a TX (transmitter), RX (receiver) and batteries. That way all the servos, motor, ESC (electronic speed control) are already in and won't need much fiddling with.

HobbyKing is the obvious choice for cheap Chinese stuff, but what about stuff over here? Anyone got any ideas for online shops in the UK?

Flaperons deploy like flaps, so you get more lift at low speeds, but they still move like ailerons to give control. For flaperons, you need to use an extra channel on the receiver so the aileron servos plug into a channel each, throttle, rudder and elevator as normal. Then, in my case, you set the models wing type to flaperon in the radio, and how much flaps you want in the radio. I only did this as I already had a six channel receiver, so might as well use the extra features of my radio instead of running a Y lead to the ailerons.

Right... so you have separate ailerons and flaps, but the ailerons work as they normally would, and the flaps deploy to give extra lift but move in relation to the ailerons?

And would you call it setting up a 'mix' to get the working in the required fashion? Is that right?

This is where it starts to get complicated. :o

EDIT: Ah no, seems like the ailerons only are used by extending downwards further to act as flaps, whilst retaining movement to act as ailerons. That's why they need a channel each.

Can you set it up so the flaps also move with the ailerons?

Wish I had found GiantCod before I went on my HobbyKing spendathon. The prices there are pretty damn good when you factor in the costs of getting stuff imported from China.

Would you recommend that transmitter over the FlySky? Is it just plain better because you don't need to faff around flashing it?
 
It's going in an FPV Raptor.

I have bought a whole bunch of props, from 6x4 to 8x6 3-blade, so I am going to see how it fares. Like I said, it might be a bit much for such a tiddly motor. :p

I didn't even figure they might kill the battery. I've only got 2200mAh 3s 20C batteries coming, so 23A is the maximum judging by Google. So about 250watts?

If I run two batteries in parallel presumably I can double the amp draw? Probably end up cooking my ESC at any rate.
 
Thanks. I don't remember how I stumbled upon that motor but it was a copy of a Suppo (?) motor that was available over here on the cheap, so just went and bought it.

Where would I get a thin prop from? Is that what they're sold as - thin propellers?

As for speed - don't really know what I want or what to expect! I'll just be happy if it arrives and I can fly the thing! Like I say I've been running around buying upgrades without even knowing what the stock stuff is like, so will see how it runs on stock then whack it on 10 minutes later to see how fast it goes. :D

I did see this Alishanmao on youtube running a 'screamer' motor on his FPVRaptor and on full tilt this thing really flies fast...

Went to http://www.sloughrc.com/ earlier today... Have to say I didn'nt learn a lot there. I always try to "buy local" even if it can be more expensive, but clearly there it's not just a "little" more expensive, and I didn't feel that being local would be if any help.

Oh well, back to the internets :-)

The hobby shop where I live were selling the Spektrum DX5 that arknor recommended for £95... online at the Kings Lynn store it was £45. :o

I know they have extra costs but it did feel like they were chancing at that for the money, when I asked about it he did seem particularly interested in me...
 
That is an excellent video. Nicely done and epic scenery. :eek:

Must resist the urge to splurge more money. :o I think I'll get a cheap 720p camera just to stick on my plane when it comes so I can get some aerial footage whilst flying normally.

My plane has finally been shipped though... finally. No batteries though, that's in another order, so will no doubt have to wait another 3 weeks for that to be delivered. :p

I was also thinking last night that I could get another couple of those motors and rig up my plane to be a Tristar. Pooweeerrrr. :cool:

Haha yeah. I am sure it will be plenty fast enough for numbnuts here. ;) I might see if I can find a motor that I can bodge onto it that will be able to hack the 3x8x6 prop to get some proper speed out of it though... just for a laugh though. :cool:

BusError are you looking at UK available planes?

There's a 2m version of the FPVRaptor that I've bought - are you still intending to shove cameras and the like on it? Looking at that SkyClimber there really doesn't appear to be any space to mount anything in it.

They have GPS, aye, but I think unless you want to make something yourself that works via the mobile network, then it won't be available. I don't think you'd want to anyway.

They have RTTH functionality that means if they lose contact with the transmitter, the plane will automatically head home and either circle in the sky or just land at a given set of co-ordinates.

Lots of people have managed roundtrips into tens of miles, so with the right kit you can do an awful lot. Lots of £££ though. The transmitter/receiver for a long range one (25+ miles) seems to be about £250, then you've got the video tx/rx, on screen displays, GPS, batteries, the plane... plus you need a 'base station' where you have all the receivers set up and a TV/goggles to get the first person view from the plane.

Even then there seems to be a knack in setting it up, so even if you spend £1k on this stuff you're not guaranteed the best results.

Like I say the live feed back isn't HD, just the recordings from the plane. Everything that comes back is rough looking to a certain extent, due to interference etc.
