Marcus Posted May 9, 2007 Share Posted May 9, 2007 Who will be building the new Eze-Fan? I'm going to build one, but as I've only just started power, can anyone help me with all the electric terms? Quote Link to comment Share on other sites More sharing options...

Marcus Posted May 10, 2007 Author Share Posted May 10, 2007 Im only considering, but I do not understand the speed 400/500/480 and speed controller/battery setups. Its all very confusing!And thanks for offering to help!Marcus Quote Link to comment Share on other sites More sharing options...
David Ashby - Moderator Posted May 10, 2007 Share Posted May 10, 2007 Marcus Nigel told me that BRC Hobbies will be doing a package of bits for the model, you know - motor, fan unit, esc and li-po for (don't quote me) £60. More in the next issue of course but give BRC a call in the meantime. David. Quote Link to comment Share on other sites More sharing options...
nasa_steve Posted May 11, 2007 Share Posted May 11, 2007 marcus speed 400/480/500 are designations given to the old brushed can motors and refer to their size 400 being the smaller of the three. brushless motors whilst still having a size equivilant to the fore said motors are much more powerfull but the sizes are still used as a benchmark figure. the esc (speed controller) basically has to be able to handle the current demanded by a said motor as does a battery need to be able to deliver that current. most stockists are able to supply a package suitable for the job in hand so most of the hard work has already been done in these cases.look in the next issue and a lot more will be revealedregardsnasa Quote Link to comment Share on other sites More sharing options...
Jonathan Lewzey Posted May 11, 2007 Share Posted May 11, 2007 For my electric flight equipment, i tend to buy through RCM Direct (www.rcmdirect.co.uk) who do good brushless motors and ESCs at amazingly low prices. Take a look at their EDF fan and brushless motor combos. About £20 for fan and motor! I don't know the weight of the Eze-fan, but the smallest one produces 720grams of thrust at 13.5v. If you used a 3s Lipo, this would probably be fine for the Eze-fan. To see what ESC you should use, look at the max current draw on the motor spec. Remember, always use an ESC that handles more current than the motor. For which size flightpack to use, look at your target weight.Jonathan Quote Link to comment Share on other sites More sharing options...

vicman Posted June 30, 2007 Share Posted June 30, 2007 I love the looks of it. It reminds me of the "Fan Trainer" pusher for 1/2a. I have it set aside and most likely will include it in this winter's building schedule. Quote Link to comment Share on other sites More sharing options...
leigh hodson Posted July 1, 2007 Share Posted July 1, 2007 think il give it a go, got enough gear lying around. ive never built solid wings tho, will be fun to see how light they come out. maybe get the hotwire out and cut a couple of foam wings for comparison. Has anyone got one flying yet? Quote Link to comment Share on other sites More sharing options...
Chumbawumba Posted July 1, 2007 Share Posted July 1, 2007 I've just got the planks and am going to start building one this month. This is my first own build after learning to fly with ARTFs. I've got a multiplex space scooter, which I love, that is quite a similar plan form to this, so hopefully I should be to hard to get the hang of flying it...I was just hoping someone could help me out with a little query. As I understand it from my space scooter, the arelons have different up/down deflections to avoid inducing yaw. I have not had a plane with seperate elevator servos before, and was wondering if there is any special way to set them up or anything? do I need a computer type transmiter to control the deflections or is my old fashioned Futaba OK? Cheers... Quote Link to comment Share on other sites More sharing options...
Salvador Grau Posted July 1, 2007 Share Posted July 1, 2007 It depends on wich one is your old fashioned Futaba. But most probably yo own one wich would be able to program flaperons and then you must connect first aileron(right one) in channel one, and the second aileron connected to the channel 5,6 or 7 (it depends in your transmiter and the way you programmed it).If you want link my email in the messenger and I would help you in all you need and I could. :DAnd now, could anyone please help me in how to get the eze-fan plans?, please :)Nice flights!!!

leigh hodson Posted July 2, 2007 Share Posted July 2, 2007 You can ofset surface movement the old fashioned way, mechanically. If you set your servo arms slightly forward then there is more movement when they push back. if you follow? So if your servos are mounted as per plan set the arms slightly forward to get more down movement. Would be so muchg easier to show with a drawing. Slightly back and there will be more up throw. I think and i may be wrong but its better to have more down deflection as this creates less drag. Glider pilots should know this!! i can se it helping with edfs a lot since you want to make every bit of power you have count and really minimise drag.

leigh hodson Posted July 13, 2007 Share Posted July 13, 2007 Been flying my eze fan and its been fun. a little too much fun. my battery hit lvc and i had to make a forced downwind landing. came in fast but steady the grass was wet and slid out across a patch of cow poo and rough ground where the cows had been digging. lost the skid and the boom came off. Bugger!!! Quote Link to comment Share on other sites More sharing options...
matthew andrews Posted July 30, 2007 Share Posted July 30, 2007 hi,does anyone sell any pre-made eze-fan's at all as i cant build,many thanks all Quote Link to comment Share on other sites More sharing options...
David Ashby - Moderator Posted July 30, 2007 Share Posted July 30, 2007 In a word 'No' Matthew I'm afraid, plan build only. Can't build? no such word as can't! You've got to start somewhere and as long as you're a competent flyer (ie. able to fly what you build) then the Eze-fan is as good a plaxe as any to start, get stuck in and you may surprise yourself.

Chad Mofford Posted July 31, 2007 Share Posted July 31, 2007 Hi Chaps, Can anyone suggest an enlargement size/percentage for the eze-fan jet. My EDF unit is 84mm internal dia, motor is 2570Kv, 45a, on 3c Lipo with 1.85lbs of thrust (flying weight. At least I'll be able to see it!ThanksChad Quote Link to comment Share on other sites More sharing options...

GREGORY WILLIAMS Posted August 12, 2007 Share Posted August 12, 2007 Hi Guy's Here in Aust we still havn't got the August issue, and i'm hanging out to have a go at building the EZY-FAN. Can anyone give me in plain English the size of the fan in inches, the of the motor in K/v. I intend to bring in the fan and motor in from Hong Kong from United Hobbies. They have a site thats worth looking at.So, I need the above info. Quote Link to comment Share on other sites More sharing options...
David Ashby - Moderator Posted August 19, 2007 Share Posted August 19, 2007 GregoryThe model was designed for a 68mm unit and a 3300Kv motor and 3s 2100mAh Li-Po. You'll need to enlarge the design for larger units. David. Quote Link to comment Share on other sites More sharing options...
Chad Mofford Posted August 19, 2007 Share Posted August 19, 2007 Hi GuysFlew my Eze-Fan for the first time today. It got about 50 yards away and b ecame un controleable. Did'nt do a range check with motor running, wally!! No damage was done but I get VERY bad interference between motor and ESC and dare not fly it again as controle serfaces flaps about wildly at 50 yard range with motor running.For info, I scaled up the plans by 12% as I am using 74mm internal dia fan insted of 68mm with a 30A ESC.Can anyone give any idears on how to rectify my dilemma.ThanksChad Quote Link to comment Share on other sites More sharing options...
Dave Hickman Posted August 20, 2007 Share Posted August 20, 2007 Hi guys, Im new to electric flight, flown IC for about 18 months Bought a very well built Eze-fan at a show last week for a cracking price (£30) with fan and brushless, couldnt believe my luck. Fitted all the other bits but would be greatful if someone could give me a clue as to balancing it as i have no plans which show me the centre of gravity. And any tips for balancing electric planes.I have always flown ic with a bit of "nose heavy". Is it the same for electric and does having the fan fitted in the centre of the plane make a diferance. Much appreciatedDave Quote Link to comment Share on other sites More sharing options...
David Ashby - Moderator Posted August 20, 2007 Share Posted August 20, 2007 DaveBargain ! Just a tad under 9.5cm bach from the leading edge on the plan. A little nose heavy never goes amiss for the first few flights. There isn't a rule of thumb for electric models Dave although getting the C of G correct is normally easier as all you have to do is move the battery around. The build article was in the July issue. Back issues available of course. David. Quote Link to comment Share on other sites More sharing options...
Dave Hickman Posted August 20, 2007 Share Posted August 20, 2007 Hi David,many thanks for the advice, could do with the plan how do i obtain a back copy of July's issue.Dave Quote Link to comment Share on other sites More sharing options...
