We want rotors , we want rotors :angry:!
It has rotors........but not the sort you are thinking of. It has instructions which are completely worthless. The only vital piece of information that is essential for safe flight is not mentioned but wastes 4 pages on telling you what should happen to control surfaces if you move a stick on the transmitter.

It really does look good.
It would be a smooth enough runway for those little wheels but at 1.8kg and 1.5m wingspan I might have to ask others to move out of the way. Xavier, can you test fly it? Do you think you can hover it?

I understand the link did not work for Albert. So go to the HobbyKing site, Planes, Foam planes, now on first page and there are 33 in stock.
I have checked out all the supplied ESCs and EDF units and was pleased to find all work just fine but not a lot of thrust from one, I hope four together do the business. So I have taken the plunge, reached for the 30min epoxy and glued the horizontal stabilisers in. Enough excitement for today. Must spread this project out as there are not many pieces to it, it is meant to be a winter build. Perhaps the fin tomorrow......

Of course they are They fly at Yellowknife and Juno Alaska all the time...lol
Too cold to fly so will try to make some more progress on the A380. Removed and re-installed the aileron and elevator servos properly, connected them to the control surfaces. Sorted out the slop in the wing joiners, installed the nose gear then trial fitted the wing to body join for the first time, all fits really good. Checked out the wheels, all 18 of them.
Started to sort out the spaghetti and where it all should go. After lunch I will try to install the EDF units in the right place. Keeping the hanger rash under control is quite hard with such large, soft parts. I will have to think about transportation damage and how to stop it.

:D:D:Dgood one Albert. Great job Mick. Did you buy one more pico tigre moth or did you keep the box as a souvenir... just kiding Mick
I forgot to give the box to Ionel, it is full of the offcuts, good for repairs.
Took the plunge and fitted the EDF units, all glued OK with UHU POR contact adhesive, just need to get them in the right place, first time. Then sorted out most of the spaghetti - 4 speed controllers. I have wired it so that the inboard engines are ganged together to use one battery with the outboard engines using the other, a bit if redundancy. The two batteries are 3S 3000mAh. I will use a UBEC to avoid all the speed controllers being wired to the receiver. I have yet to decide where the receiver is going, probably above the wing located on the fuselage wall. Put the wing on to take some photos but it was already dark so not very good pictures, I need to take it to somewhere with some small grain ashfelt to look more realistic than my apartment floor.
Time for a Caesar and chill for a while, enough excitement for one day.

Twin ESC, just like my ARF P-38, but only for this spring. Tell me Mick , did you use a Y for or you hope to use the aux slot for the second ESC
It has 4 ESCs in two pairs with all leads connected together via 3 Y leads. I thought of trying to use differential thrust as it has no rudder but decided not to as I preferred to have the inner and outer EDFs running from different batteries but they all get identical signal from the receiver. I removed the red wire from each ESC to the receiver, so will use the UBEC to power the receiver from one of the batteries.
Burning Head
2010-01-30, 11:21 PM
With the two fuselage in the lightning and for weight factor, lest wire. I choice the Y option for now... and two lipo 4 cell 1000mAh. If you go the other way, think about the battery wire setup for twin engine for two lipo runing in parallel ... I got the pic from a RC site, imagine the weight for 2... I will post pic of my P-38 whit out hyjacking the threat

Xavier
2010-01-31, 01:17 AM
I like the double Y harness for a twin on 2 batteries. I suppose that it's not as much neccessary on the 4 motors if the 2 inboard are on one battery and the two outboard on the other one. It's like 2 twins on one battery each.
Why would you not use the differentiel because of your batterie arrangement. The ESC don't really care were the power is coming from I think. You should be able to do it anyway. Maybe you could do it on the ontboard motors only as it will have more effect. Am I missing something ?

and don't forget the strobes,,, worth it on such a flying ladie ...
Can anybody recommend a lighting kit for this? It would be good.
Xavier, I agree, it should be possible but I only have a 6 channel radio and want aileron differential, so not sure how to do it.
PaulG-rc
2010-01-31, 07:24 AM
Hi Mick
I thought you wanted to have power differential but you mean aileron differential.
Most radios have it and if not it can be done on the servo arms.
You just need to place the servo arms so that the travel is less for the aileron downward and more upward preventing drag on the down aileron and more efficient in the turns.
For the lights well I oredered those but didn't recive them yet, should get them sometime this week as he told me he posted them last wed.

Denis has those here so he could answer you on how they are

2010-01-31, 10:40 AM
The one I use are fine. Connect on a separate switch to be activated remotely or with a Y harness on any Chanel of the radio, on a separate battery or the same one finally they can be activated manually by a switch provided. All possibility is there for 30$

I will bring next indoor.
Burning Head
2010-01-31, 04:31 PM
Buy at the 1 $ store, just have to remouve the aligator plastic sh... even the aerodinamic cut look like real beam:cool:
Thanks for the info, I like the lights you have got Denis, all set up for the right size aircraft. I will order them, thanks.
Just to clarify, I will set up aileron differential, as I do on a number of models but I am hoping to have power differential as well. I have worked out how to do it with two mixes: Ch3 to Ch5 to get the left and right output then CH4 to CH5 to modulate CH5 thrust.
I am not happy with this as the total thrust will go up and down with rudder, anybody got a better idea? I think I need another mix to say reduce power on CH3 on left rudder but then if CH3 reduces then CH5 will as well so I go round in circles, or my plane will, help, I am confused. Has anybody done this before, if so how?
I have just found the answer to my own question on differential thrust in RCGroups:
http://www.rcgroups.com/forums/showthread.php?t=489099
All explained very well but it needs three mixes and my Futaba 6EX only has two, so I will have to save up some more $. This is the first time its limitations have restricted my fun.

You need a Futaba 12FG... the number of combinations and mixes will keep you busy two winters....

2010-02-02, 05:24 PM
Why stop at the 12FG ? Go for the 14MZ :-) It could even play music while you fly ...
Jeremy Cartlidge
2010-02-03, 03:24 PM
Mick,
If you have saved enough money for the 14MX, you could get 70 6 channel Hobby King radios for the same price. That would give you 210 mixes.
The cheap way (1 radio) would give you 3 mixes for $32.95 (plus $3 for the PC USB cable).
I have taken the plunge and ordered a Hitec Aurora 9 from Great Hobbies. Not in stock anywhere in the US or Canada that I could find but most suppliers are expecting deliveries in late February or early March.
Did some more work on it today. I have set up the ESCs, control surfaces and installed the UBEC and a receiver. Also fitting Deans plugs to six batteries (without shorting them out in the process!)
Tested the whole set-up, awesome noise when all 4 EDFs are running. Cleared some furniture out the way and taxied in the apartment a few metres, fantastic. Checked the CofG and it comes out quite nose heavy as I am using 2 3S 3000mAh batteries rather than the 1 suggested in the instructions. Other people who have flown this aircraft have used two 3000mAh batteries or one 5000mAh and their CofG comes out about 230-250mm from the leading edge, mine is 210 with both batteries and 230 with just the one. However the fuselage is huge so plenty of room to move the batteries back. The flying weight in the instructions was 1.8kg, mine is 2.15kg, the additional battery weighs in at 233g so I don't know where the remaining excess weight comes from as everything else is standard or supplied in the kit.
Need to do some slow speed taxi trials, now where can I do that in winter??

Sure Mick you can bring it to the indoor and taxi. As long as you don't get airborn I thinck will be fine. I'll bring my cam.
Cheers
I know some people took some video, so where is it?
Talk at the indoor about thrust prompted me to fetch the small digital kitchen scales. With 2 fresh 3000mAh batteries rigged with one to the inner EDFs and the other to the outers, I measured 1.33kg static thrust. With the all up weight of 2.14kg producing a thrust to weight ratio of 0.62. This compares very favourably to the real aircraft thrust to weight ratio of 0.23 (4x 70,000lb thrust/ 1,240,000lb MTOW). So scale performance should be good, not grossly over-powered.
Roll-on spring so we can see it in the air.

I should sound really cool with the 4 EDF's
It flies!!!!!
The wind eventually died down, so I had no more excuses so with help from Gilbert as official helper/trimmer and Albert as official photographer it took to the skies. Thanks guys. It only needed 4 clicks of up elevator to get it trimmed straight and level. It flew for about 4min, plenty for a first flight, then an approach and a reasonable landing. Only then could I stop shaking and taxi it back in. PHEW. Any pictures or video of it would be greatly appreciated. I will post my own, once I find the USB lead for the camera.

Nice looking plane, Mick. I had noticed it on the Hobby King website and thought it would make people sit up and take notice. How is it as a sport flyer? Is it a plane that you would fly regularly?
It is not a sport flyer that zooms round the sky doing aerobatics. It flies like a good scale aircraft should with a power to weight ratio of about 0.5, this compares to real thing at 0.3. Smooth take-off but good climb-out, very stable and great in low passes. I did not try to fly slowly on the first flight, will try that later. The approach was easy to set up and the landing was probably the best I have done in a long time as it was straight with a decent roll before stopping. Can I do it again?? However, do I want to fly it regularly? Absolutely, it was a real thrill and looked fantastic.
If you look on the H-K forum at the A380 posts you will see the main draw-back is the small scale-like wheels which need a smooth surface. I am concerned that on some parts of our runway where there are overlaps in the fabric they will rip the nose gear off. I was careful to avoid these yesterday.
briankizner
2010-05-02, 03:14 PM
Thanks for the informative reply, Mick. I guess I will not order it as my first electric- the runway I am flying off is coarse gravel. I don't think I'll be able to reach a good takeoff speed with those wheels.
Brian, two more great flights today. One good landing and one not so excellent landing as I ran just off the runway onto the grass which caused the nose wheel to be released from its magnets, it acts as the battery hatch and one main gear became detached but just needed gluing back on. All repaired at the field.
I can recommend the E-Flite Pulse XT25e as a great electric sport plane. I had one until yesterday when a momentary lapse of concentration caused by two pilots calling landing at the same time and not sorting it out caused me to look away from the model for a second and the rest is history, just like the Pulse.

Congratulation Mick Nice flight nice landing. I hope to see it next time am out.Nice aircraft.
Thanks for the comments guys. Great video Bill, well done.
Albert, that first one was meant to be a low pass, not a landing but it did get lower than I expected as the glide angle is pretty steep with all that undercarriage. I have yet to explore just how slow it will go. The batteries needed 1380mAh after the first flight of 4min. So the second and third were 7min each on fresh 3000mAh batteries. I think 6min is about right as I could tell that the power had fallen off towards the end.
